Answer:
$2.85
Step-by-step explanation:
First, we’re going to find the total the Uncle paid:
8.7 + 10.3 = 19
15% is 0.15 (You divide 15/100)
To find how much the tip was, we multiply 19 and 0.15
19(0.15) = 2.85
The uncle left a $2.85 tip
You can use distributive property because 62 and 8 share a greatest common factor, which is 8.
4(2+7)

For equations that model direct variation, they are of the form y = kx, where k is the constant of proportionality.
So, for there to be a constant of proportionality of 1/2, the equation should be y = 1/2 x.
This is the same as y = 3/6 x (since 1/2 = 3/6), so the answer is C.
76.91 = C
cos(77)= (17-3)/ C
Your answer is 4/5, which is 80% or 0.8
If there are 20 marbles in total in the bag, and 4 blue ones, that means that the probability of taking a blue one is 4/20.
This means that the probability of not taking a blue one is 1 - 4/20, or 20/20 - 4/20, which equals 16/20 = 4/5
