Answer:
38
Step-by-step explanation:
The area is 3/8 yd².
Area = length x width
Given:
length = 3/4 yard
width = 1/2 yard
Area = 3/4 yd * 1/2 yd
Area = 3*1/4*2
Area = 3/8 yd²
In multiplying fractions, multiply the numerators, then, multiply the denominators. lastly, simplify the fraction. 3/8 yd² is already in its simplest form.

Answer:
2.88
Explanation:
If you break down the equation we see that 8 is the number of boxes and 1.44 is the price of each box. So if you wanted to change the equation the formula would be: (1.44)x = cost so if you wanted to figure out how much 2 boxes would be, you just plug in 2 for x and you get (1.44)2 = 2.88
Answer: a burger is $5.25, fries are $1.50
b = burger, f = fries
3b + 3f = 20.25
5b + 8f = 38.25
First, solve for b in terms of f
3b = 20.25 - 3f
b = 6.75 -f
Then substitute that for b in the other equation to solve and get a numerical value for f.
5(6.75 -f) + 8f = 38.25
33.75 -5f +8f = 38.25
33.75 + 3f = 38.25
3f = 4.5
f = 1.5
Now substitute that in to get a numerical value for b
b = 6.75 - 1.5
b = 5.25
Checking the math:
3b + 3f = 20.25
3(5.25) + 3(1.5) = 15.75 + 4.5 = 20.25
