It’s is 82 because you are supposed to do multiply first then add it witch does 82
Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
These r the answers for ur questions
4x+7=-3
4x=-3-7
4x=-10
X=-10/4
X=-2.5
The area is 35. Look at the sketch below for explanation!
