Answer:
4 & 7 are the correct answers for this equation.
I'm pretty sure you would multiply the cost amount to the percentage
Answer:
75% may also be expressed as 75/100=3/4 or as 0.75 as needed.
Let x = the number
Translate:
"if 75% of a number is 60" means
(75/100) * x = 60 [the word "of" usually means multiply]
(3/4) x = 60 [reduce or just write it this way]
x = 60(4/3) [multiply both sides by 4/3]
x = 80
Step-by-step explanation:
Answer:
w = 4 1/2
l = 6
Step-by-step explanation:
w = width
2w-3 = length
A = lw
27 = w(2w-3)
27 = 2w² - 3w
subtract 27 from each side:
2w² - 3w - 27 = 0
factor:
(2w-9)(w+3) = 0
solve each for 'w':
w = 9/2
w = -3 (This answer can be discounted because a length cannot be negative)
width = 9/2
length = 2(9/2) - 3 which is 6
67912 rounded to the nearest 10th is 67910
