Hello from MrBillDoesMath!

Answer:

Discussion:

Let the number be "n". Then the question states that

3n - 15 = (n/2) + 5 => multiply both sides by 2

6n - 30 = n + 10 => subtract n from both sides

5n - 30 = 10 => add 30 to both sides

5n = 30 + 10 = 40 => divide both sides by 5

n = 40/5 = 8

Thank you,

MrB

Solving the inverses of these functions and applying the composite we obtain:

(G⁻¹ о F⁻¹) = X

Note that (F⁻¹ о G⁻¹) also results in X (see second annex)

Is 40/1000 equivalent to 40%

No, 40/1000 is equal to 4%. 40/100 or 400/1000 would be 40%

Dakota wants to build 8 birdhouses, he needs to point 6 square feet of plywood, for each birdhouse is the plywood cause $0.56 pe

Westkost [7]

Answer:

$26.88

Step-by-step explanation:

Cost of a ply wood = $0.56 per square foot

If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:

8 * 6

= 48 sq. feet

Hence the area of 8 bird houses is 46sq. feet

Next is to calculate the amount it will cost to make the 8 bird houses.

Since 1 sq. foot = $0.56

48 sq. feet = y

cross multiply

y * 1 = 48 * 0.56

y = 26.88

Hence it will cost Dakota $26.88 to make hid bird houses
