1. describe two ways the numbers in each proportion are related.
a) 5: 20 = 125: 500 b) 10: 1 = 120: 12 c) 75: 25 = 300: 100
d) 1: 3 = 16: 48
2. multiply between ratios to determine each value of n.
a) 2: 5 = 8: n b) 2: n = 6: 9 c) n: 5 = 12: 20
d) 8: n = 4: 15

3. multiply within ratios to determine each value of z.
a) 4: 8 = 3: 2 b) 5: 2 = 6: 18 c) z: 14 = 10: 20
d) 3: 21 = z: 56

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

no i do not : ( what is it?

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
