Volgvan

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.

I hope this helped. I am sorry if you get this wrong.

butalik [34]

Answer:

Using 3.14 for pi A = 113.0 ft^2

Using the pi button A = 113.1 ft^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi ( 6)^2

A = 36 pi

Using 3.14 for an approximation for pi

A = 36(3.14) = 113.04

To 1 decimal

113.0

Using the pi button

A = 113.0973355

A = 113.1

Find the distance between (-5 3) and (4 -5)

ruslelena [56]

Answer:

19 or √145 ≈ 12.04

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

Distance = √ ( x ₂ − x ₁ )² + ( y ₂ − y ₁ ) ²

Substitute the actual values of the points into the distance formula.

√ ( 4 − ( − 5 )) ² + ( ( − 5 ) − 3 ) ²

Simplify:

√ 145

The result can be shown in multiple forms.

Exact Form:

√ 145

Decimal Form:

12.04159457 … ≈ 12.04

Solve for g.<br> 3=9/-4 - 5

barxatty [35]

Answer:

g = -32

Step-by-step explanation:

3 = g/-4 - 5

Multiply both sides of the equation by -4

-12 = g + 20

Swap sides so that the variable terms are on the left hand side

g + 20 = -12

Subtract 20 from both sides

g = -12 - 20

Subtract 20 from -12 to get -32

g = -32
