Answer:

$x=2$

Step-by-step explanation:

We have been given an equation $4x+8=16$ . we are asked to find the value of x that makes our given equation true.

Let us solve our given equation for x using opposite operations.

Subtract 8 from both sides:

$4x+8-8=16-8$

$4x=8$

Divide both sides by 4:

$\frac{4x}{4}=\frac{8}{4}$

$x=2$

Therefore, $x=2$ is the solution for our given equation.

Let us verify our answer:

$4x+8=16$

$4(2)+8=16$

$8+8=16$

$16=16$

Both sides are equal. Hence proven $x=2$ is solution for our given equation.

horsena [70]

Answer:

Deal A) 90% Profit ; Deal B) 60% Profit

Step-by-step explanation:

Multiple ways of solving this problem here is one way:

100k-10k = 90k(Revenue) : Then you make this as a percent by 100k then multiply it by 100.

100*((100,000-10,000)/100,000) = 90%

The same is true for the other equation:

100*((50,000-20,000)/50,000) = 60%

Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and

scoundrel [369]

Answer:

The correct answer is the last option, that is, $112 + 25m + 45 = 50 + 60m$

Step-by-step explanation:

We have been given that the first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. Therefore, amount of money in the account of first running after m months will be: $112+45+25m$

We have been given that the second runner has $50 in savings and will save $60 each month. Therefore, amount of money in the account of second running after m months will be: $50 + 60m$

In order for amount of money to be equal in accounts of both the runners, we set up:

$112+45+25m=50+60m$

Upon rewriting the left hand side using commutative law, we get:

$112+25m+45=50+60m$

Therefore, we can see that the last option is the correct answer.

At smith’s Mountain Lake Boat Rentals, it cost $25 per hour to rent a pontoon boat, plus a one-time

sergey [27]

Answer:

Jones family paid a total of $139

Step-by-step explanation:

Smith's Mountain Lake Boat provides Rental services that can be expressed as follows;

Total cost=cost per hour×number of hours rented+one time cleaning deal

For Benael's family;

Benael family total cost=Cost per hour×number of hours rented+one-time cleaning deal

where;

Benael family total cost=$226.50

Cost per hour=$25

Number of hours rented=11 am-6:30 pm=7 hours 30 minutes=7.5 hours

One time cleaning deal=x

Replacing;

226.50=(25×7.5)+x

187.5+x=226.50

x=226.50-187.5

x=39

One time cleaning deal=$39

For Jones family;

Jones family total cost=Cost per hour×number of hours rented+one-time cleaning deal

where;

Cost per hour=$25

Number of hours rented=9 am-1 pm=4 hours

One time cleaning deal=$39

Replacing;

Jones family total cost=(25×4)+39

Jones family total cost=$139

Jones family paid a total of $139
