Answer:
55
Step-by-step explanation:
2 + 6m + 7 = 57
pls show your work pls.
i need a full answer
Answer:
m=8
hope this helps
have a good day :)
Step-by-step explanation:
2 + 6m +7=57
9+6m=57 add like terms
6m=48 subtract 9 from each side
m=8 divide by 6 on each side
Answer:
M=8
Step-by-step explanation:
First your going to subtract 2 from 7 and thats 5.
then your going to do:
6m+5=57
Then subtract 5 from 57 and thats 52
and divide 52 from 6 and thats 8.
8.

How many liters of water are in a tank with a volume of 4,500 cm3
1 L = 1,000 cm
04.0L
0 4.5 L

Another statement is, "Volume is directly proportional to the number of moles."
The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.
STP is 0 °C and 1 bar.
One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L
Example Problem
A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Hi I am really bad at math and need to know about fractions I HATE MATH I’m super nervous so ya if you know anything about fractions please help me!!! :)
Answer:
how to add and subtract fractions
Step-by-step explanation:
ok so we can start with adding so when you add fractions you can first start out by making the denominators the same number to make it easier so here is an example
7/9 + 3/10 you could make the denomonatiers the same or just do 9x10 and 7x10 + 3x9 and 10x9 and then if you multiply the numbers and added up all the sums you would get to fractions 70/90 + 27/90 so you add them up and science the denominators are the same you just leave them the same number so it would just be 70+27 so you would get 97/90 and because the denominator is 90 and we have 97 for the numerator 97 fits into 90 1 time with 7 left over so the whole number would be 1 and then 7/90
Step-by-step explanation:
Multiplying Fractions:
example: 2/3·2/3
multiply numerator=top number2·2=4 multiply denominator=bottom number3·3=9combine the terms..4 and 9=4/92/3·2/3=4/9Dividing Fractions:
example: 2/3*2/3
reverse second fraction thats getting divided..2/3=3/2convert into multiply symbol.2/3·3/2multiply the like terms..2/3·3/2=6/6..2/3*2/3=1 whole..Combine Fractions:
example:2/3+2/3
keep denominator and combine numerator only if denominator is the same..2+2=4combine the numerstor and denominator..4 and 3=4/32/3+2/3=1 1/3Subtract Fractions:
example:2/3-2/3
keep denominator if similar..subtract numerator..2-2=0combine numerator and denominator..0 and 3=0/32/3-2/3=0A circle is drawn inside a square so its circumference touches each of the four sides of the
square. If the area of the circle is 125.8cm2 calculate the length of the sides of the square.
Answer:
12.66 cm
Step-by-step explanation:
Area of the circle = 125.8 Sq cm
[tex] \therefore \: \pi {r}^{2} = 125.8 \\ \\ \therefore \: 3.14 \times {r}^{2} = 125.8 \\ \\ {r}^{2} = \frac{125.8}{3.14} \\ \\ {r}^{2} = 40.0636943 \\ \\ {r} = \sqrt{40.0636943} \\ \\ r = 6.32958879 \\ \\ r \approx \: 6.33 \: cm \\ \\ d \: = 2r \\ \\ d = 2 \times 6.33 \\ \\ d = 12.66 \: cm \\ [/tex]
Diameter of the circle = 12.66 cm
Since, circumference of the circle touches each of the four sides of the square.
So, length of the sides of the square
= diameter of the circle.
= 12.66 cm

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then
[tex](x,y)\to (-x,-y)[/tex]
We know that,
[tex]1260^\circ=1080^\circ+180^\circ[/tex]
[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]
After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.
[tex](7,12)\to (-7,-12)[/tex]
The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.
Please help out if you can-!

Milo earns his regular pay of $12.00 per hour for up to
40 hours of work per week. For each hour over
40 hours of work per week, Milo earns 1 times his
regular pay. How much does Milo earn in a week in
which he works 45 hours?
Answer: $540
Step-by-step explanation:
If Milo works 40 hours for the week, he earns $12.00 per hour.
If Milo works anything over $40, he makes 1 times his normal pay which means that he is making the same amount over 40 hours as he is under 40 hours.
If he works 45 hours therefore, his pay is:
= 45 * 12
= $540
A housekeeper had 3/7 of a spray bottle of a cleaning solution. Used 1/9 of the solution in a day . How much of the bottle did she use
Answer:
27/7 or 3 6/7
Step-by-step explanation:
3/7 divided by 1/9 = 27/7
rounded to 3
Have a nice day
The 0.317 spray bottle did she us.
It is required to find how much of the bottle did she use.
What is fraction?A fraction having whole numbers for the numerator and denominator. A fraction is a number of the form: ab where a and b are integers and b≠0. It represents the division of two numbers.
Given:
We know that total =1
For a cleaning solution=3/7 of a spray bottle
Used=1/9
According to given question we have,
Subtract the fractions
3/7 - 1/9
Calculate the difference,
=20/63
=0.317
Therefore, the 0.317 spray bottle did she us.

You have $500 in a savings account. How long will it take to double that
amount at an 8% annual interest rate?
Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000

You have written equation for Main Street and Elm street. Since both equations are start with y=, how can you combine these two equations to write a new equation that involves only x?
Answer:
The two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only
Step-by-step explanation:
If the starting of both the equation is from "Y=" then it means that whatever equation (having x variable) they are representing will be equal to each other as both the equation on one side are ultimately equal to Y
For example
Y = 3X + 5 ---- Eq (1)
Y = 7X +6 ---- Eq (2)
So both are equal
3X + 5 = 7X + 6
4X + 1 = 0
In this way the two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Four basketballs and six baseballs cost $44. Five basketballs and four baseballs costs $48. Determine the cost for one basketball and one baseball.
Answer:cost for basket ball= $8 and
cost of baseball = $2
Step-by-step explanation:
Step 1
Let the cost of basket ball be represented as x
and cost of baseball = y such that
Four basketballs and six baseballs cost $44 will be expressed as
4x+ 6y= 44 --- eqn 1 also
Five basketballs and four baseballs costs $48 will be expressed as
5x+ 4y= 48--- eqn 2
Step 2
Having obtained two expressions we can now sole
4x+ 6y= 44 --- eqn 1
5x+ 4y= 48--- eqn 2
multiplying eqn 1 by 5 and eqn 2 by 4
20x+ 30y =220---- eqn 3
20x+ 16y=192-----eqn 4
subtracting equation 4 from 3 we now have
14y=28
y= 28/14
y=2 = $2
from equation 1
4x+ 6y= 44, putting the value of y=7 to find x
4x+ 6(2)= 44
4x+12= 44
4x= 44-12
4x=32
x= 32/4
x=8=$8
cost for basket ball= $8 and
cost of baseball = $2

What is the value of 6x+7y−5 when x = 2 and y = 3?
Answer:
28
Step-by-step explanation:
6(2) + 7(3) - 5
12 + 21 -5
It's a good idea to get into the habit of using parenthses
when substituting numbers in for variables.
Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.
Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.
