Question

Please help me with this ​

Answer 1

7. 5
`(5)/(8)` pizza

8. B

9. 11
`(1)/(5)` inches

10. -12

11.
`(3)/(20)`

12. 4

Explanation:

7. 3
`(1)/(2) \\` + 2
`(1)/(8)`

make them mixed fractions:
`(7)/(2)` +
`(17)/(8)`

get a common denominator by multiplying
`(7)/(2)` by 4:
`(28)/(8)` +
`(17)/(8)`

add the numerators:
`(45)/(8)`

simplify the fraction by dividing 45 by 8: 5
`(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
`(3)/(5)`

multiply 7 by 1
`(3)/(5)`: 11
`(1)/(5)`

L = 11
`(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:
`(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.
