Answer 1

The answer is:

d = -18

3(d + 5) - 7 = 2(d -5). Plz Have The Work Written Down. I Don't Know How To Do This. It's Hard. Plz Help
Answer 2

Answer:

d=-18

Step-by-step explanation:

3(d + 5) - 7 = 2(d -5)

Distribute the number outside the brackets, inside them

3d+15-7=2d-10

3d+8=2d-10

solve for d with isolating it

3d= -8+2d-10

3d-2d= -8-10

d=-18

a group of friends went to lunch the bill sales tax and tip was 48.60 a sales tax of 7% was added the group then tipped 18% on the amount after the sales tax was added what was the amount in dollars of the sales tax(show the steps pls)

A tower 15m high casts a shadow 30m long. A nearby telephone pole casts a shadow 16m long. Find the height of the telephone pole. Plz show ur work, thx slatttttt

Answers

Answer:

8 feet.

Step-by-step explanation:

If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio

[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.

Hope this helped!

The answer should be 8 feet

divide both sides by -4

-4x/-4 = -20/-4

simplify

x = 5

Creed's brother earns $12.00 per hour. The store offers him a raise -- A 5% increase per hour. After the raise, how much will Creed's brother make per hour?

Answers

Answer:

$12.60

Step-by-step explanation:

Creed's brother originally makes $12.00 an hour. A 5% raise means that:

$12.00 × 1.05 = $12.60

If you raise $12.00 by 5% then you have the formula
12x0.005=0.006
12+0.6=12.6
So after the raise Creeds brother will make $12.60/hour
