Answer:

57 °

Step-by-step explanation:

Complementary angles = 90 °

Since, Your angle don't have ∠ [  ] Then Let let "C" and "y"

Thurs, C = 12x- 3  and y = 7x - 2

It is given that angles r and s are complementary  angles. Two angles are complementary  if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,

c + y = 90

12x - 3 + 7x - 2 = 90

19x - 5 = 90

19x = 95

x = 95/19

x = 5

Using the value of x in expression or r, we get:

c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.

So measure of angle c is 57 degrees.

Hence, the ∠ is 57 °

2x + 3 + 4x + 6 + 12x + 18 = 477<br><br> Please answer with solving steps. Thanks guys :)

Answer:

x= 25

Step-by-step explanation:

2x + 3 + 4x + 6 + 12x + 18 = 477

FIRST combine like terms

take all "x"

2+4+12= 18x

take all whole numbers

3+6+18= 27

18x+27= 477

now solve for x

-27 on both sides

18x= 450

÷18 on both sides

x= 25

If 4=3x+16, find the value of x-7 (show work)
viktelen [127]

Answer:

-11

Step-by-step explanation:

First get x alone.

Subtract 16 from both sides: -12 = 3x

Divide both sides by 3: -4 = x

Plug in x: -4 - 7 = -11

PLZZZ CHECK ME<br><br> Is this correct, if not please help me.
Gwar [14]
Hello! For this question, you solve using order of operations, which you probably already have remembered as PEMDAS. Anytime a number is raised to the 0 power, that is equivalent to 1. 0.5^0 is 1. 250 * 1 is 250. x = 0 gives us the answer of 250. Now, let's solve for the number by the second power. 0.5² is 0.25. 250 * 0.25 is 62.5. x² gives us 62.5. Now, let's subtract the two numbers together. 250 - 62.5 is 187.5. Because the number is decreasing, the slope is negative, so the answer is -187.5. Your answer is correct.
