Answer:
$136.50
Step-by-step explanation:
100 - 12 = 88% (How much percentage of money the student left)
88% = 120.12
1% = 120.12 ÷ 88 = 1.365
Before buying the book, the student had 100%
100% = 1.365 x 100 = 136.50
Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
The variable b represents the area of the base of the prism or pyramid. Hope that helps!
