y = - 25
since x varies directly with y then we can express the relationship as
x = ky ← k is the constant of variation
to find k use the given condition y = - 10 when x = 4
k =
=
= - 
hence x = -
y
when x = 10
10 = -
y
multiply both sides by - 5 and divide both sides by 2 )
- 50 = 2y ⇒ y = - 25
2/5 is equivalent to 6/15
3 ounces is equal to 45/15
she mixes 1/15 green for every 6/15 of blue or 5/15 less than blue so
she should mix 40/15 ounces or 2 10/15 or 2 2/3
Answer:
a. 30 b. 54
Step-by-step explanation:
a. 3(3+5) + 2(3)
24 + 6
30
b. 7(8) + 4 - 8 +2
56 + 4 - 8 + 2
56 - 4 +2
52 + 2
54
22 > 5(2y + 3) - 3y
22 > 10y + 15 - 3y
22 > 7y + 15
22 - 15 > 7y
7 > 7y
7/7 > y
y < 1
