Answer:
What triangles?
Step-by-step explanation:
Answer:
12.94 gallons/week
Step-by-step explanation:
44x5=220
220/17=12.94
225 inches squared
half of the base: 20/2=10
10x30=300
AREA of the whole triangle=300
3/4 of 300=225
The answer to the first one is:
x=-5/4y+-1/2. Why?
In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer
The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.
Hope this helps :^)
