Answer:

c=5

Step-by-step explanation:

Sorry I did a problem just like this on my paper so im just gonna copy my work

Simplifying

2x + -5 = 2x + -1c

Reorder the terms:

-5 + 2x = 2x + -1c

Reorder the terms:

-5 + 2x = -1c + 2x

Add '-2x' to each side of the equation.

-5 + 2x + -2x = -1c + 2x + -2x

Combine like terms: 2x + -2x = 0

-5 + 0 = -1c + 2x + -2x

-5 = -1c + 2x + -2x

Combine like terms: 2x + -2x = 0

-5 = -1c + 0

-5 = -1c

Solving

-5 = -1c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add 'c' to each side of the equation.

-5 + c = -1c + c

Combine like terms: -1c + c = 0

-5 + c = 0

Add '5' to each side of the equation.

-5 + 5 + c = 0 + 5

Combine like terms: -5 + 5 = 0

0 + c = 0 + 5

c = 0 + 5

Combine like terms: 0 + 5 = 5

c = 5

Simplifying

c = 5

Answer:

Step-by-step explanation:

5GP= BP

2BNP= GNP

BP+BNP=333

GP+GNP=225

BNP= 333-BP

BNP= 333-5GP

GP= 225-GNP

GP= 225-2BNP

BNP=333-5(225-2BNP)

BNP=333-1125+10BNP

-9BNP=-792

BNP=88

Hope it helps :)

Savatey [412]

Answer:

7.5 miles per hour.

Step-by-step explanation:

We have been given that Mr. Ward runs a lot. He ran 45 minutes each day, 5 days each week, for 16 weeks.

First of all, we will find time for that Mr. Ward ran in 16 weeks.

We will multiply 5 by 16 to find number of days for that Mr. Ward ran and then we will multiply the result by 45 minutes to find the time.

$\text{Time for that Mr. Ward ran in 16 weeks}=16\times 5\times 45\text{ minutes}$

$\text{Time for that Mr. Ward ran in 16 weeks}=3600\text{ minutes}$

Now, we will divide 3600 minutes by 60 minutes to convert time into hours as:

$\text{Hours}=\frac{3600}{60}=60$

Now, we will divide 450 miles by 60 hours to find Mr. Ward's average speed as:

$\text{Mr. Ward's average speed}=\frac{450\text{ miles}}{\text{60 hours}}$

$\text{Mr. Ward's average speed}=\frac{7.5\text{ miles}}{\text{ Hour}}$

Therefore, Mr. Ward's average speed in 7.5 miles per hour.
