Answer:

x = 8

Step-by-step explanation:

40 + 6x + 2 = 90° because these angles are complementary

6x = 90 - 42

6x = 48 divide both sides by 6

x = 8

Answer:

Step-by-step explanation:

Well they add up to a straight line which would be 180 degrees. That means 40, 6x+2 and 90 all add up to 180

40 + 90 + 6x + 2 = 180

Evaluate.<br> 21 + } + (-)) -<br> Enter your answer as a mixed number in simplest form in the box.
andrew-mc [135]

Evaluate: 2(1/4) + 2/5 ÷ (-1/2) - 1/4

⇛9/4 + 2/5 ÷ (-1/2) - 1/4

Take the LCM of the 4 and 5 is 20.

Again, 2 and 4 is 4.

⇛[(54+8)/20] ÷ [(-2 - 1)/4]

⇛62/20 ÷ (-3/4)

⇛62/20 × 4/-3

⇛62/{5*(-3)}

⇛62/-15.
