Answer:
the width is 0.7 feet
Step-by-step explanation:
Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.
7 = 10 * x, or 7 = 10x
Now, solve for the width, or x, by dividing both sides by 10.
7(/10) = 10x(/10)
7/10 = x
Simplify 7/10 = 0.7
So the width of the banner is is 0.7 ft!
15 times 5 = 75 so approx. $75
Answer:

m = slope
b = y-intercept
Step-by-step explanation:
Well if finding X you get 4,-7 when you simplify the whole equation you get that as well.
Answer:
Dakota=20 perry=25 together= 45
Step-by-step explanation:
First step, remember to keep 5
second step, if they are find keep multiplying until they both meet the same number which is 20, but they both have 20. But Perry will have 25 since he started a day before
