First you add 8x on both sides and then you get -3y=8x+24 then you divide -3 on both side and you get y=-8/3x-8 so then the y intercept is 8 and the slope is -8/3. Hope this helped.

Answer:
18 miles an hour
Step-by-step explanation:
Divide 432 by 24 to get 18.
Answer:
see explanation
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
=
[ 2a₁ + (n - 1)d ]
where a₁ is the initial value and d the common difference
Given
=
[ 10 + (n - 1)3 ]
Then by comparison
2a₁ = 10 ( divide both sides by 2 )
a₁ = 4 ← initial value
and d = 3 ← common difference
Thus
=
[ 10 + (7 × 3) ]
= 4(10 + 21)
= 4 × 31
= 124
Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
= 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
- Given that Ann used 8 gallons of gas.
Therefore,
Distance covered by Ann's car in 8 gallons = 39 × 8
= 312 miles
Therefore, Ann drove 312 miles in 8 gallons.
