Answer:
x= -8
Step-by-step explanation:
1/2x + 13=9
- move 13 to the other side
1/2x= 9-13
-simply 9-13
1/2x= -4
-multiply 2 on both sides
1x=-8
x=-8

Answer:
10 quarters
x=10
Step-by-step explanation:
25 pennies equals to .25 ⊄
6 nickels equals to .30⊄
2 dimes equals to .20⊄
Add it up: 25+30+20=75⊄
You will then subtract .75 from our total:
3.25-.75=2.50
You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.
Eight quarters will equal 2.00
and two quarters equals 50.
Add it up, 10 for 2.50.
You will have 10 quarters.
X=10
You find circumference w the diameter given
equation
