Answer:
3.0233088 x 10 raise to power 7
Answer:
n(x + y + z)
Step-by-step explanation:
The total number of apples bought is x+y+z. The total expense is the product of the cost and the number bought. If each one costs "n", then the cost is ...
n(x +y +z)
21+3x=-15
3x=-15-21
3x=-36
x=-36/3
x=-12
P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50
284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99
