Answer:

3a - 2ab if a= 4 and b= 6 = -36

-7x + 5 = 8x -25 solve for x = 2

Step-by-step explanation:

Evaluate 3 a - 2 a b where a = 4 and b = 6:

3 a - 2 a b = 3×4 - 2×4×6

3×4 = 12:

12 - 2×4×6

-2×4 = -8:

-8×6 + 12

-8×6 = -48:

-48 + 12

12 - 48 = -(48 - 12):

-(48 - 12)

| 4 | 8

- | 1 | 2

| 3 | 6:

Answer: -36

_________________________________________

Solve for x:

5 - 7 x = 8 x - 25

Subtract 8 x from both sides:

5 + (-7 x - 8 x) = (8 x - 8 x) - 25

-7 x - 8 x = -15 x:

-15 x + 5 = (8 x - 8 x) - 25

8 x - 8 x = 0:

5 - 15 x = -25

Subtract 5 from both sides:

(5 - 5) - 15 x = -5 - 25

5 - 5 = 0:

-15 x = -5 - 25

-5 - 25 = -30:

-15 x = -30

Divide both sides of -15 x = -30 by -15:

(-15 x)/(-15) = (-30)/(-15)

(-15)/(-15) = 1:

x = (-30)/(-15)

The gcd of -30 and -15 is -15, so (-30)/(-15) = (-15×2)/(-15×1) = (-15)/(-15)×2 = 2:

the following equation represents the total distance (d) that the Benson family has traveled from their home, after traveling 10
Pani-rosa [81]

Answer:

The distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents  292.5 miles

Step-by-step explanation:

The given equation for the distance the Benson family traveled from their home can be presented as follows;

d = 55·t + 100

Where;

d = The total distance that the Benson family has traveled from their home after traveling 100 miles to pick up their grandparents

t = The time duration the Benson family have been traveled from their grandparents home on the way to their vacation

To find how far from their home the Bensons will be after 3 1/2 hours of driving with their grand parents, we substitute t with 3 1/2 hours or 3.5 hours as follows;

d = 55·t + 100

When t = 3\frac{1}{2} hours, we get;

d = 55 \times 3\frac{1}{2} + 100 = 292.5  \ miles

Therefore, the distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents = 292.5 miles.
