Answer:
The costs will be the same at 21 pounds.
Step-by-step explanation:
Let p be the number of additional pounds. (Total weight would be p+1).
UPS cost = 7 + 0.20p
FedEx cost = 5 + 0.30p
We need these to be equal.
7 + 0.20p = 5 + 0.30p
0.10p = 2
p = 20
The answer is: b) a = 63°
Add both the equations together to eliminate x
x+5y=8
-x+2y=-1
7y=7
y=1
Now fill in y into the original equation
x+5(1)=8
x+5=8
x=3
Now you can check by filling x and y into the second equation.
-(3)+2(1)=-1
-3+2=-1
-1=-1
So your answer will be (3, 1)

Answer:
-1(2+x)
Step-by-step explanation:
in the initial equation the -1 was distributed, this answer creates a product (multiplication). -1(2+x)= -2-x
