Problem 21 :
The equation y = 1.5x can be used to determine y, the number of cups of water needed to cook x cups of rice. Which table shows the relationship between x and y?
Solution :
y = 1.5x
x = 9, y = 1.5(9) ==> 13.5
x = 11, y = 1.5(11) ==> 16.5
x = 13, y = 1.5(13) ==> 19.5
x = 15, y = 1.5(15) ==> 22.5
So, option A is correct.
Problem 22 :
A temperature in degrees Fahrenheit is shown in expanded notation.
(9 × 10) + (4 × 0.1)

= 90 + 0.4
= 99.4
Problem 23 :
Mark has $5.25 in quarters. He spent all this money on 3 sports drinks. He spent the same amount for each sports drink.
Which equation can be used to find the amount of money Mark spent for each sports drink?
A) 5.25 × 3 = 15.75 B) 5.25 ÷ 7 = 0.75
C) 5.25 ÷ 3 = 1.75 D) 5.25 × 7 = 36.75
Solution :
Total value = 5.25
Number of parts = 3
Value of each part = 5.25/3
= 1.75
5.25 / 3 = 1.75
So, option C is correct.

= (1 + 40)/4
= 41/4
= 10 1/4 cup
So, option A is correct,
Problem 28 :
A hexagon and its side lengths are shown.
What is the perimeter of the hexagon in feet?
