3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)
Therefore, we know that x is equal to 18, and so the answer is E.
I think it’s either b or c. But I’m leaning more towards c
Answer:
1.0 mph
Step-by-step explanation:
so there are 60 minutes in an hour
you need to find what her speed is per hour
right now it is per minute
so multiply her current speed by 60
88*60=5280
there are 5280 feet in a mile.
Her current speed is 1 mile per minute
rounded to the nearest tenth of a mile is
1.0 mph
Answer:
2x-5= -20
move -5 to the other side
sign changes from -5 to 5
2x-5+5= -20+5
2x= -15
divide by 2 for both sides
2x/2= -15/2
cross out 2 and 2, divide by 2 and 2 and then becomes x
x= -15/2
