14-3(5t-12)=1-(20t+1) How am I supposed to do this?

Expand by multiplying out:

14-15t + 36 = 1 -20t -1,
Because of the minus before the bracket, it changes the sign inside the bracket
-15t + 20t  = 1-1-14-36  Rearranging the ts on one side and the numbers on other
                                   side.
5t = -50  Divide both sides by 5.
t =  -50/5
t = -10.

What is the formula for 'percent of change'?
Marina CMI [18]
First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease. ( copy and paste from skillsyouneed.com )

An angle measures 72 degrees more than the measure of its complementary angle what is the measure of each angle
labwork [276]

Good evening

Answer:

<h2>measure of Angle 1 = 81°</h2><h2>Measure of angle 2 = 9°</h2>

Step-by-step explanation:

we need to solve this system

x + y = 90 (1)

x = y + 72 (2)

If we substitute x by y+72 into the equation (1) we will get

(y+72) + y = 90 ⇔ 2y + 72 = 90 ⇔ 2y = 90 - 72 = 18 ⇔ y = 9

then x = 90 - 9 = 81
