On a map, 1 inch equals 15.4 miles. If two cities are 3.5 inches apart on the map, how far are they actually apart?
Answer:
They are actually 53.9 miles away.
Step-by-step explanation:
1 in = 15.4 mi
Set up an equation:
Variable x = number of miles
1/15.4 = 3.5/x
Cross multiply:
1 × x = 15.4 × 3.5
x = 53.9

Step-by-step explanation:
Together, two pipes can fill a tank in 3 hours.
One pipe alone can fill the tank in 5 hours.
How long does it take for the other pipe to
fill the tank alone?
Answer: 7.5 (h)
Step-by-step explanation:
Let say
a the outflow of the first pipe
b the outflow of the second pipe
T the volume of the tank.
x the time for filling with the second pipe
two pipes can fill a tank in 3 hours: a*3+b*3=T
One pipe alone can fill the tank in 5 hours : a*5=T
3*b=T -3a ==> 3b= 5a*3a=2a
b=2a/3
b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1
x=15/2 = 7.5 (hours)

Which equation is an identity?
A. (9x/15) + 27 = (9x/15) + (27/15)
B. 3((x/2) + 16) - 16 = (3/2)x
C. -4(3 - 2x) = -12 - 8x
D. -5((x/15) - 16) - 30 = 50 - (1/3)x
E. 36((3/4)x- 2) + 72 =-72 + 27x
Answer:
C.
Step-by-step explanation:
An equation is an identity if the equation is always true regardless of what value you replace 'x' with.
This means we need to simplify the equations above to see which one will be true for any value of 'x'.
After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

Answer:
d = 3
Step-by-step explanation:
(7d+3)/4 = 6
Multiply each side by 4
(7d+3)/4*4 = 6*4
(7d+3) = 24
Subtract 3 from each side
7d+3-3 = 24-3
7d = 21
Divide by 7
7d/7 = 21/7
d = 3
the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in
8 x 6 = (4 6) + (
x6)
= 24 +
Answer:
4,24,48
Step-by-step explanation:
For the first equation, they are splitting 8 in half. So 8/2 would be 4. The 4 would go in the first box.
Then 4x6 is 24 in the second box.
Then just add 24 and 24. 24+24=48
And your last answer is 48.

What's -1.55 as a fraction? show work please help
Answer:
hope it's help you dear
Step-by-step explanation:
The decimal part of your number seems to have the repeating digit 5 in it.
Your original number to convert is 1.550000. Let's slide the decimal point in this number to the right 1 place(s) (the same number of digits in the number 5).
If we do this, we'll get a 15.500000 (slide the decimal in the 1.550000 right 1 places, you'll get 15.500000).
So what? Well now, we have two numbers with the same repeating decimal parts, 15.500000 and 1.550000.
Now let's just work a little algebra into all of this. Let's call your original number x. And in this case, x=1.550000. The number with the decimal point slid over can be called 10x, because 10x=15.500000
What if we subtracted these two equations (that is, subtract the items on the left of the equal sign
from the stuff on the right of the equal sign)?
10x = 15.5
- x = 1.55
----------
9x = 13.95.
Now here's the important result of doing all of this: Notice how all of the repeating decimal parts have subtracted away to zero! We are left with a nice, simple 14 on the right side of the equal sign.
Now, solving 9x=14 for x by dividing both sides of it by 9, we'll get that x=14/9. And this is your answer.
How is this your answer? Well remember that above, x was originally set equal to 1.550000 via x=1.550000, and now we have that x is also equal to 14/9, so that means 1.550000=14/9..and there's 1.550000 written as a fraction!
The fraction is an improper fraction (the numerator is greater than the denominator).
While there is nothing incorrect about this, an improper fraction is typically
simplified further into a mixed number.
The whole number part of the mixed number is found by dividing the 14 by the 9.
In this case we get 1.
The fractional part of the mixed number is found by using the remainder of the division,
which in this case is 5 (14 divided by 9 is 1 remainder 5).
So your final answer is: 1.550000 can be written as the fraction
What is the inverse of v(x)= -3/4x - 1/3?
Step-by-step explanation:
v(x) = y = -3/4x - 1/3
y + 1/3 = -3/4x
x = -4/3 × (y + 1/3)
you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).
and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x
y = -4/3 × (x + 1/3) = -4x/3 - 4/9
please help me with this thank you
hi <3
1) as the value ahead of the tenths position is a 5, you would round up.
this gives you the answer of 1.6
2) as the value ahead of the hundredths position is a 4, you would round down.
this gives you the answer of 1.55
3) as the value ahead of the thousandths position is an eight, you would round up.
this gives you the answer of 1.555

Lets verify
[tex]\\ \sf\longmapsto a_2=\dfrac{a_1}{10}\times 4[/tex]
[tex]\\ \sf\longmapsto a_2=\dfrac{500}{10}\times 4=50(4)=200[/tex]
And
[tex]\\ \sf\longmapsto a_3=\dfrac{a_2}{10}\times 4[/tex]
[tex]\\ \sf\longmapsto a_3=\dfrac{200}{10}\times 4=20(4)=80[/tex]
