Answer:

(The ones underlined are the equation)

1) Let the number be x

<u>x + 16 = 58 </u>

x = 58 - 16

x = 42

2) let the number be x

<u>x * 8 = 80 </u>

x = 80/8

x = 10

3) let the number be x

<u>12/x = 3 </u>

x = 12/3

x = 4

4) let the number be x

<u>x - 8 = 21 </u>

x = 21 + 8

x = 9

Deffense [45]

Answer: Approximately d = 208.72

============================================================

Work Shown:

Make sure your calculator is in radian mode

A quick way to check is to compute cos(pi) and you should get -1

cos(angle) = adjacent/hypotenuse

cos(x) = 200/d

cos(0.29) = 200/d

d*cos(0.29) = 200

d = 200/cos(0.29)

d = 208.715135166392 which is approximate

d = 208.72

I rounded to two decimal places since x is rounded in that manner as well. Round however else you need if your teacher instructs.

An equation is:
2(x+3)-7=9
Distribute the 2
2(x)+2(3) -7=9
2x+6-7=9
Combine like terms
2x-1=9
Add one to both sides
2x-1+1=9+1
2x=10
Divide both sides by two to isolate the variable.
2x/2=10/2
x=m
