Step-by-step explanation:
I did the math
X=7
Step 1: add nine to both sides it becomes
-2x=-23+9 —> -2x=-14
Step 2: divide by -2 on both sides it becomes
X=-14/-2 —> x=7
She has 2 $20 and 1 $10 bills.
Since it says that she has 1 more 20 dollar bill, we should subtract 50 by 20.
That gives us 30.
Then we should subtract it AGAIN, 30 by 20.
That gives us ten.
Finally, well subtract that, 10 by 10.
Equation:
[50-(20x2)]-10

Answer:
43.25 feet.
Step-by-step explanation:
We have been given that school club needs 300 feet of rope for a project.
First of we will change given lengths of ropes in feet.

1 yard =3 feet
32 yards= 3*32 feet = 96 feet.
12.5 yards = 3*12.5 feet = 37.5 feet.
Let us find the amount of rope school already have by adding all the given amounts.


Now let us subtract 256.75 feet from 300 feet to find the amount of rope that school club needs to complete the project.


Therefore, the school club needs 43.25 feet of additional rope to complete their project.
