Answer:
t+5+x
Step-by-step explanation:
It says Jenny ran 5 more miles than last week so you find the number from last week then add 5. X is the miles she ran this week
There are 12 in. in 1 ft.
So, that means that there are 48 inches in 4 ft.
You multiply 4 ft by 12 in to get 48

Step-by-step explanation:
Answer:
$480
Step-by-step explanation:
Perry makes 15% commission for each TV he sells.
How much would he have to sell a TV to get $72
First of all, let's call the unknown variable x
So 15% of x= $72
Mathematically, this would be represented as 15/100 * x= 72
15/100x= 72
Breaking down further,
15/100 can be broken down to 3/20
3/20x= 72
So to find the value of x, we divide both sides by 3/20
x= 72 ÷ 3/20
x= 72 * 20/3 (using the law of indices)
x= 1440/3
x= $480 dollars.
So, Perry would have to sell a TV for $480 to make a $72 commission.
2250= plastic beads
6750= metal beads
STEP 1:
Find total number of beads on clearance
= 2250 + 6750
= 9000 total beads on clearance
STEP 2:
set a ratio; number of plastic beads on clearance to the total number of beads on clearance is what number out of 100
x= percent out of 100
2250/9000= x/100
cross multiply
(9000*x)= (2250*100)
9000x= 225,000
divide both sides by 9000
x= 25%
CHECK:
multiply total number of beads by 25%
= 9000 * 25%
= 9000 * 0.25
= 2250 number of plastic beads
ANSWER: 2250 beads is 25% out of the total number of beads on clearance.
Hope this helps! :)
