What is the value of b in the equation 3b + 2(b - 1) =8
WARRIOR [948]

Answer:

b = 2

Step-by-step explanation:

In order to find the value of b, we have to isolate b on one side of equation first

So,

3b+2(b-1)=8

Multiplying 2 with b-1

3b+2b-2=8\\5b-2=8

Adding 2 on both sides

5b-2+2=8+2\\5b=10

Dividing by 5 on both sides

\frac{5b}{5}=\frac{10}{5} \\b=2

So the value of b is 2 ..

A gas can is filled at the rate of 320 cubic inches per minute. The can is 10 inches long, 8 inches wide, and 12 inches high. Ho
elena-14-01-66 [18.8K]

Solution:

The gas can is filled at the rate of 320 cubic inches per minute.

The can is 10 inches long, 8 inches wide, and 12 inches high.

So volume of the can=10 in*8 in *12 in

\text{Volume of can }=960  \ in^3\\

Time required to fill the can=\frac{960}{320}=3  \ minutes\\

Hence Time required to fill the can =3 minutes.

What is the value of p if the line that passes through (2,-4) and (p,8) has a slope of 1/2? ​
Irina18 [472]

Answer:

Step-by-step explanation:

(2,-4)....x1= 2 and y1 = -4

(p,8).....x2 = p and y2 = 8

slope(m) = 1/2

now use the slope formula (y2 - y1) / (x2 - x1) and sub in what we know...

slope(m) = (y2 - y1) / (x2- x1)

1 / 2 = (8 - (-4) / (p - 2)

1 / 2 = (8 + 4) / (p - 2)

1/2 = 12 / (p - 2) .....now multiply both sides by (p - 2)

1/2(p - 2) = 12

1/2p - 1 = 12

1/2p = 12 + 1

1/2p = 13

p = 13 / (1/2)

p = 13 * 2/1

p = 26

so the value of p is 26
