Answer:

x = 2

y = 5

1 = 80

2= 10

3 = 100

Step-by-step explanation:

Complementary angles add to 90.

So 5(x+14) + 2(10-y) = 90. Solve for x.

5x + 70 + 20 -2y = 90

5x - 2y = 0

Supplementary angles add to 180.

So 5(x+14) + 121-3x-3y = 180. Solve for x.

5x + 70 + 121 -3x -3y = 180

2x - 3y = -11

This creates a system of equations. Solve using elimination.

5x - 2y = 0 ------> 10x - 4y =0

2x - 3y = -11 ------> 10x -15y = -55

_____________

11y = 55

y = 5

Substitute y=5 into the equation to find x.

2x - 3(5) = -11

2x - 15 = -11

2x = 4

x=2

Find the measure of each angle by substituting x = 2 and y =5 into each angle.

How do you solve -2 = t/3 - 11?

<h2><u>Answer:</u></h2><h2><u></u> $\boxed{t=27}$ <u></u></h2><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Multiply both sides of the equation by 3:</h3>

$\frac{t}{3}$ × $3=t$

$-11$ × $-3=-33$

<em> - We do this because we need to get x alone and separate from fraction from. </em>

<u>Equation at the end of Step 1:</u>

<u /> $-6=t-33$ <u />

<h3>2.) Add 33 to both sides:</h3>

$-33+33=$ Cancels Out

$-6+33=27$

<em> - We do this to cancel out an extra numbers in order to get only x alone with 1 number on the opposite side of the equal. </em>

Five more than the quotient of a number and 3 equals 2.

MakcuM [25]

Answer:

$\large\boxed{\dfrac{n}{3}+5=2\ or\ n:3+5=2}$

Step-by-step explanation:

$\dfrac{n}{3}+5=2\\\\\dfrac{n}{3}-\text{the quotient of a number}\ n\ \text{ and 3}\\\\...+5-\text{five more than}$

If you want a solution:

$\dfrac{n}{3}+5=2$ <em>subtract 5 from both sides</em>

$\dfrac{n}{3}+5-5=2-5$

$\dfrac{n}{3}=-3$ <em>multiply both sides by 3</em>

$3\!\!\!\!\diagup\cdot\dfrac{n}{3\!\!\!\!\diagup}=(3)(-3)\\\\n=-9$
