Answer:

7. 5 $\frac{5}{8}$ pizza

8. B

9. 11 $\frac{1}{5}$ inches

10. -12

11. $\frac{3}{20}$

12. 4

Step-by-step explanation:

7. 3 $\frac{1}{2} \\$ + 2 $\frac{1}{8}$

make them mixed fractions: $\frac{7}{2}$ + $\frac{17}{8}$

get a common denominator by multiplying $\frac{7}{2}$ by 4: $\frac{28}{8}$ + $\frac{17}{8}$

add the numerators: $\frac{45}{8}$

simplify the fraction by dividing 45 by 8: 5 $\frac{5}{8}$

8. 3 x 6 = 18

5 x 6 = 30

7 x 6 = 42

9 x 6 = 54

therefore, y = 6x

9. 5:7 is similar to 8:L

divide 8 by 5: 1 $\frac{3}{5}$

multiply 7 by 1 $\frac{3}{5}$ : 11 $\frac{1}{5}$

L = 11 $\frac{1}{5}$ inches

10. 5 - 2x = 29

subtract 5 from each side: -2x = 24

divide each side by -2: x = -12

11. fruit = 15%

15% = 15/100

simplify by dividing by 5: $\frac{3}{20}$

12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
