7/8a=42
a=42*8/7 (times both sides by 8/7 to cancel the fractions)
a=48
Answer:
3/4 = 16/x. Step-by-step explanation: Set up the original ratio: 3:4 (a.k.a. 3/4 or 3 to 4) Because 16 correlates to red paint and 3 correlates to red paint the will be in the same location (as the numerator or denominator).. Also, the amount of blue paint is unknown so that is x.4 also represents blue paint, so 4 and x will also be on the same level (as the numerator of denominator).
Step-by-step explanation:

We're going to change one unit at a time. Let's start with inches to feet. There are 12 inches in 1 foot. Divide 240 by 12 or multiply by 1/12.

Next, let's do the time using the same idea. Remember that there are 60 minutes in 1 hour.

Answer: 1200 feet per hour

Answer:
Step-by-step explanation:
not sure sorry
You can find the slope using the points.
9-18 -9 9
--------- = ------- = -------
-14+10 -4 4
Next, you can find the equation of the line.
y-9=9/4(x+14)
y=9/4x+40.5
Plug in 0 for x.
y=9/4(0)+40.5
y=40.5
So, the y-intercept is (0,40.5)
Plug in 0 for y.
0=9/4x+40.5
-40.5=9/4
x=-18
So, the x intercept is (-18,0)
I hope this helps!
