Step-by-step explanation:

first find out how much x can be by using 180 degrees.

(5x+3)°+(5x+3)°+58=180°

(10x+6)°+58°=180°

10x°+64°=180°

10x°=116°

x=11.6°

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.

two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they
Rashid [163]

Answer:

The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.

Step-by-step explanation:

If x is the rate of the first mechanic, and y is the rate of the second mechanic, then:

10x + 5y = 1500

x + y = 195

Solve the system of equations using elimination or substitution.  Using substitution:

10x + 5 (195 − x) = 1500

10x + 975 − 5x = 1500

5x = 525

x = 105

y = 195 − x

y = 90

The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.
