Answer:
x <-2
Step-by-step explanation:
-3x+6>12
Subtract 6 from each side
-3x+6-6>12-6
-3x> 6
Divide each side by -3, remembering to flip the inequality
-3x/-3 < 6/-3
x <-2
Answer:
(x-5)*7 = 7x - 3
Step-by-step explanation:
If x is the number, then 5 less is x-5
I believe the answer is B 19.2
You use the pyth.
15^2+12^2=369
Then find the square root of 392 which is 19.2
<span>(1 gallon)/(20 miles) = (x gallons)/(180 miles)
1/20 = x/180
1*180 = 20x
180 = 20x
20x = 180
</span><span>x = 180/20
x = 9
It takes 9 gallons of gas to drive 180 miles
(9 gallons)*(3.98 dollars/1 gallon) = 9*3.98 dollars = 35.82
Round to the nearest dollar: 35.82 ---> 36
It costs $36 to travel 180 miles</span>
