solve for x 3(x+2) + 4(x-5)=10
Answers
Answer:
x= 3.43
Step-by-step explanation:
First, use the distributive property and multiply 3 by x and 3 by 2:
3x + 6
next use the distributive property again and multiply 4 by x and -5:
4x - 20
Combine Like terms: 3x + 6 + 4x - 20
3x + 4x = 7x
6 - 20 = -14
Now Add 14 to both sides: 7x - 14 = 10
10 + 14 = 24
Now divide 7 by both sides: 7x = 24
24 / 7 = 3.428571429 = 3.43
Answer:
x=24/7 or 3 3/7
Step-by-step explanation:
3(x+2) + 4(x-5)=10 parenthesis first
3x+6+4x-20=10
7x-14=10 addition on both sides
7x-14+14=10+14
7x=24
x=24/7
check the answer:
3(x+2) + 4(x-5)=10
3(24/7+2)+4(24/7-5)=10
72/7+6+96/7-20=10
168/7-14=10
24-14=10

Sunita bought a 10 kg box of grapes from the market. She gave 3 1/2 kg of her grapes to her friend Reena and 2 1/4 kg to Anita. How many kilograms of grapes were left with her?
Answers
Answer:
17/4 kg
Step-by-step explanation:
Sunita has = 10kg of grapes
Quantity given out :
To Reena =3 1/2
7/2 kg
To Anita =2 1/4
9/4 kg
Total quantity of grape given out
7/2+9/4
(14+9)/4
23/4
Quantity left after giving out = Total quantity of grape before giving out minus quantity of grape given out
10/1 - 23/4
40-23)/4
= 17/4 or 4 1/4
Hence, she has 17/4 kg of grape left with her
On the following number line, two rational numbers are graphed. Represent the two numbers as fractions (or mixed numbers) in lowest terms, and write two different expressions to represent the difference between them. Then, find the difference, showing all of your work.
Answers
Answer:
The answer is below
Step-by-step explanation:
A rational number is a number in the form p/q where p and q are both integer numbers.
From the number line, each one unit is divided into six, therefore each one point is 1/6 unit. For the first number, it is between 0 and 1 and is on the fifth point, therefore the expression of the first number = 0 + 5(1/6) = 0 + 5/6 = 5/6
For the second number, it is between -1 and -2 and is on the third point, therefore the expression of the second number = -1 - 3(1/6) = -1 - 3/6 = -9/6
The difference between the two numbers is:
5/6 - (-9/6) = 5/6 + 9/6 = 14/6

or,12-2x = -2y + 2x
or, 12 = - 2y + 4x
or, 12/2= 2x - y

• 2x -6= y.....eqn_1
-2x=-2y+2x -12
or,4x +2y= -12
or,4x + 2(2x-6)= -12
or, 4x+4x-12=-12
or, 8x= 0
• x= o

PLEASE HELP, WILL GIVE BRAINLIEST IF CORRECT!!!! (08.06 MC) Mike and his friends bought cheese wafers for $2 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $25 to buy a total of 20 packets of wafers of the two varieties. Part A: Write a system of equations that can be solved to find the number of packets of cheese wafers and the number of packets of chocolate wafers that Mike and his friends bought at the carnival. Define the variables used in the equations. (5 points) Part B: How many packets of chocolate wafers and cheese wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer. (5 points)
Answers
Answer:
x = 5 , y = 15
Step-by-step explanation:
You can solve this using substitution.
Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y
2x + 1y = 25
x + y = 20
These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).
For part B I used substitution because it was more applicable to the question then addition or elimination.
ACTUAL WORK
Set 2x + 1y = 25 equal to x
x = 25 - y / 2
Replace x with y in the second equation
(25 - y / 2) + y = 20
And solve for y
y = 15
Since we know what y is we can replace y in the second equation and find what x is
x + 15 = 20
Solve for x
x = 5

HOPE IT HELPS
Answer:
Below
Step-by-step explanation:
We are given that <PMO= (3a+15)° and NMO= (6a-6)°
Notice that the sum of <PMO and <NMO gives a right angle.
● <PMO+<NMO = 90°
● 3a+15+6a-6 = 90
● 9a + 9 = 90
Substruct 9 from both sides
● 9a +9 -9 = 90 -9
● 9a = 81
Divide both sides by 9
● 9a/9 =81/9
● a = 9
So the value of a is 9°
■■■■■■■■■■■■■■■■■■■■■■■■■■
MN and PO are parallel since MNOP is a rectangle.
MO is crossing MN and PO so <POM and < NMO are alternate interior angles wich means that they have the same size.
● <NMO = <POM
● <POM = 6a-6
The value of a is 9°
● <POM = 6*9-6 = 48°
So <POM = 48°

Answers
Answer: The ice sheet's thickness decrease every 6 weeks= 1.5 meters
Step-by-step explanation:
GIven: At the beginning of spring, the ice starts to melt. The variable sss models the ice sheet's thickness (in meters) t weeks after the beginning of spring. [tex]s=-0.25t+4[/tex]
At t=0, [tex]s=4[/tex]
So, Thickness of ice sheet at the beginning = 4 meters
Now at t= 6, we get

To change a 12 hour clock to a 24 hour clock, note that when it hits p.m., anything over 12 p.m. will have the number added to it.
a) 2:30 am
2:30 am is earlier than 12 pm, therefore, 0230 is your answer. Remember, you must place the 0 in the front to not confuse a user that the 2 is in the tens place value.* *Essentially, use military time:
b) 1:15 pm
1:15 pm is later than 12 pm, therefore, add 12 to the 1 in the hours. Use military time:
0115 + 1200 = 1315
1315 hours is your answer.
To change a 24 hour clock to a 12 hour clock, note the time frame in which the time is given. if over 1200, then subtract by 12, and add the p.m.

Nala has 'n' marbles. Paul has three times as many marbles as Nala. Nala loses 5 marbles and Paul buys 10 marbles. Together they now have 105 marbles. Write down and solve an inequality in 'n'
Answers
Answer:
Step-by-step explanation:
Nala's marbles = n
Paul's marbles = 3n
nala loses 5 marbles
so nala's marbles = n - 5
paul buys 10 marbles
so paul's marbles = 3n + 10
Total marbles = 105
so,
n - 5 + 3n + 10 = 105
By transposing,
n + 3n = 105 - 10 + 5
4n = 100
n = 100 / 4
n = 25
