When you add the numbers together you get 665. Then you divide them by 7 you get 95. I think the answer is 95.

Solve for k 4.5+1.5k=18−3k

sertanlavr [38]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}$

Step-by-step explanation:

$\sf{4.5 + 1.5k = 18 - 3k}$

Move 3k to left hand side and change it's sign

Similarly, move 4.5 to right hand side and change it's sign

$\longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}$

Collect like terms

$\longrightarrow{ \sf{4.5k = 18 - 4.5}}$

Subtract 4.5 from 18

$\longrightarrow{ \sf{4.5k = 13.5}}$

Divide both sides by 4.5

$\longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}$

Calculate

$\longrightarrow{ \sf{k = 3}}$

Hope I helped!

Best regards! :D

Three years after paying $2800 in a startup company, you sell for $2200. The total percent return is what?

masha68 [24]

Answer:

The total percentage return is 26.19

Step-by-step explanation:

Given as :

The amount paid for three years = $ 2800

So, Total amount paid for three years = $ 2800 × 3 = $ 8400

The return amount after three years = $ 2200

The time period = 3 years

Let the percentage return = x %

So, According to question

x % of $ 8400 = $ 2200

Or, x % = $\frac{2200}{8400}$

Or, $\frac{x}{100}$ = $\frac{11}{42}$

∴ x = $\frac{11}{42}$ × 100

I.e x = 26.19

Hence The total percentage return is 26.19 Answer

A rectangular garden has a walk around it of width x. The garden is 20 ft by 15 ft. Write a function representing the combined w

kodGreya [7K]

Answer: A(x) = 15 ft + 2x

EXPLANATION

Given,

The dimension of the rectangular garden is 20 ft by 15 ft.

Dimension of a rectangle is written as Length by Width

This implies that,

Length of the garden = 20 ft

Width of the garden = 15 ft

The garden has a walk around it of width x.

The combined width of the garden = Width of garden + 2x

[we are adding twice the width of the walk because it is around the garden (this means it will add to the width of the garden on both the left and right sides)]

Combined width of the garden, A(x) = Width of garden + 2x

Since width of the garden = 15 ft

A(x) = 15 ft + 2x
