Answer:
D. 49.75 months
Step-by-step explanation:
Esme earns a net salary of $2400 per month.
In her saving account she already have a balance of $100.
She saves $100 every month after her monthly expenses.
She plans to buy a car of $20000 using a no interest loan .
She usually make a $300 payment on the loan every month.
The number of months she will save enough money to pay off her loan completely can be calculated below.
let
x = number of months
The amount she saved altogether every month is $300 + $100 = $400.
Recall she already has $100 in her account
Amount of loan to be repaid = 100 + 400x
20000 = 100 + 400x
20000 - 100 = 400x
19900 = 400x
divide both sides by 400
x = 19900/400
x = 49.75 months
Answer:
30cm
Step-by-step explanation:
5+5+12+8
The volume of the cylinder is B. 112units^3
2 ways:
1. solve for x
2. simplify the 10 so it can add to the 4/x
if you use 1. solve for x
8/x=4/x+10
subtract 4/x from both sides
4/x=10
multiply both sides by x
4=10x
divide both side sby 10
0.4=x
proportion is 8/0.4=4/0.4+10
if you use 2. make 10 addable to 4/x
4/x+10/1
multiply 10/1 by x/x
4/x+10x/x=(4+10x)/x
8/x=(4+10x)/x
multiply both sides by x to clear fraciton
8=4+10x
subtract 4
4=10x
divide 10
0.4=x
As it stands, it's none of those. I believe you were going for the distance formula but copied it wrong.
