Answer:
k = 10
Step-by-step explanation:
We first have to get the 3rd angle: 180 - 115 = 65
Sum of angles in a triangle = 180
65 + (4k + 5) + (6k + 10) = 180
Collect like terms
65 + 10k + 15 = 180
80 + 10k = 180
Subtract 80 from both sides
10k = 100
Divide both sides by 10
k = 10
i think this is your answer: 12.0 and 12.5
M = ounces of M&M
r = ounces of raisins
calories = 139m + 85r
calories < 600
139m+85r<600
The answer would be 15 because if 10 is the width after enlarging the photo graph you would do 10 divided by 3 which is 3.3333333. Then you would do 3.3333333 times 4.5 which is 15!
