Answer:
80 buckets of red paint
Step-by-step explanation:
Given
The ratio of buckets of yellow paint to buckets of red paint in the store to be 3:4
Total ratio = 3 + 4 = 7
Amount of yellow paint = 60
Required
Amount of red paint.
First get the total amount of paint used.
3/7 * x = 60
x is the total paint used
3x/7 = 60
3x = 7*60
x = 420/3
x = 140 buckets of paint
Amount of red paint = Total - Amount of yellow paint
Amount of red paint = 140 - 60
Amount of red paint = 80
Hence there are 80 buckets of red paint in the store
X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
Answer:
60 hours
Step-by-step explanation:
300 + 5x = 10x
subtract 5x from both sides to cancel 5x on the left
300 = 5x
divide both by 5
60 = x
