320-70= 250
250X1/2=125
X=125
$400.72 - This is how it’s done.
Add three to both sides
8=1/5x
multiply by 5 on both sides
40=x
Answer:
63
Step-by-step explanation:
If x units, then 2x tens
Number is: 2x(10)+x = 21x
Reversing digits:
2x units and x tens,
Number is: x(10)+2x = 12x
21x - 12x = 27
9x = 27
x = 27/9 = 3
Original number: 21x = 21(3) = 63
Answer:
1x + 0.5y = $150
Step-by-step explanation:
x = hot dog and each hot dog is sold for $1. We will multiply each hot dog sold by $1.
y = soda and each soda is sold for $0.50. We will multiply each soda sold by $0.50.
