Answer:
14 ounces of blue paint
Step-by-step explanation:
The ratio of blue to yellow is 2:7
To solve this problem we can make a proportion:
2/7=x/49
the numerator represents the blue paint, the denominator represents the yellow paint
To solve the proportion you have to cross multiply:
2*49=7*x
x=14

Answer:
10
Step-by-step explanation:
"three times r" = 3r
"three times r minus ten" = 3r - 10
"product of 5 and the difference of three times r minus ten"
= 5 (3r - 10)
given that r = 4,
the expression becomes
5 (3r - 10)
= 5 [3(4) - 10]
= 5 [12 - 10]
= 5 (2)
= 10
