Hello!</h2>
The answer is:
<h2>
Why?</h2>
To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.
For example, we have:
We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).
So, we are given the expression:
Hence, the answer is:
Have a nice day!
Answer:
18.9
Step-by-step explanation:
361-4 = 357
the root of 357 is 18.9 when rounded
ax+by=20
a represents how many first items you bought
x represents the cost of the first item
b represents how many second items you bought
y represents the cost of the second item
Step-by-step explanation:
Apples cost four times as much as oranges per pound.
If the cost of orange =x
then, cost of apples =4x
But,
the costs of apples =2.80$
So,4x=2.80
⠀
⠀
so,oranges costs for per pound =0.70$
