Answer:
D. 18
Step-by-step explanation:
- multiply both sides by 9/2, the reciprocal of 2/9.
4×(9/2)=x
- express 4×(9/2) as a single fraction.
4×9/2=x
- multiply 4 and 9 to get 36.
36/2=x
- divide 36 by 2 to get 18.
18=x
- swap sides so that all variable terms are on the left hand side.
x=18
Answer:
30
Step-by-step explanation:
Answer:
adding the two equations together
(1.5,8)
Step-by-step explanation:
8x=12
x=1.5
y=8
The answer would be the third choice.
Here’s why:
First multiply 6 and 4 to get 24.
The multiply r, r, s, and t to get r^2st.
The answer is 24r^2st.
Let
C-----------------
> charges for the purchases to the credit card
<span>r-------------------
> the interest rate </span>
X------------------
> total cost of the purchase
we know that
C=4120
r= 22.45%=0.2245
X=C*(1+r)
substituting the values in the formula
X=(4120)*(1+0.2245)=
(4120)*(1.2245)=5044.94
the answer is
$5044.94
