Answer:
x=-5
Step-by-step explanation:
first you subtract the positive 5 from the 20.
second you divide negative 3x into 15
the answer you get should be x=-5
-12 + 9y = -57
add 12 to both sides, 9y = -45
divide 9 from both sides to isolate the y
y = -5

Step-by-step explanation:
The ratio of the large cans to small cans shows the distribution of both cans
The new ratio of large cans of soup to small cans of soup in the grocery store is (b) 5 : 3 and (e) 35: 21
<h3>How to determine the ratio?</h3>
The given parameters are:
Ratio = 12 : 7
Rewrite as:
Large : Small= 12 : 7
The number of cans is given as:
Can = 114
So, the distribution of the cans are:
Large = 12/(12 + 7) * 114
Large = 72
Small = 7/(12 + 7) * 114
Small = 42
When 2 large cans are purchased, the remaining number of cans are:
Small = 42
Large = 70
Express as ratio
Large : Small = 70 : 42
Simplify
Large : Small = 35 : 21
Large : Small = 5 : 3
Hence, the new ratio is (b) 5 : 3 and (e) 35: 21

Volume of a right prism = Area of the base * height
the base is the right triangle.
Area of a right triangle = ab/2
a = 15 inches ; b = 8 inches
Area of a right triangle = (15in * 8in)/2 = 120 in² / 2 = 60 in²
V = B * h
V = 60 in² * 10 in
V = 600 in³ Choice B.
