The measures of the angles of △ABC are given by the expressions in the table. Angle Measure A (4x−13)° B 15° C (x+18)∘ What is the measure of ∠A and ∠C ? Enter your answers in the boxes. m∠A= º m∠C= º

Answers

Answer:

m∠A = 115°; m∠C = 50°

Step-by-step explanation:

∠A + ∠B + ∠C = 180

4x – 13 + 15 + x + 18 = 180 Combine like terms

5x + 20 = 180 Subtract 20 from each side

5x = 160 Divide each side by 5

x = 32

∠A = 4 × 32 – 13

= 128 – 13

= 115°

∠ C = 32 + 18

= 50°

Check:

115 + 15 + 50 = 180

180 = 180

Answer:

∠A = 115°

∠ C = 50°

The Ramirez family trip took six hours and I drove 330 miles the miles varies directly with the time they traveled write a direct variation equation to represent this situation
how far could they travel in 12 hours?

Answers

In this case you have to multiply to solve. So, you multiply the # of miles TIMES the number of hours. We know that the unit rate is 330 mph. So we multiply that with 12 hours. 12*330=3960.

By checking you must divide 3960 by 12. 3960/12=330

Writing expressions word problems Liam had $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $120 cost among the e of them.
How much money does Liam have left?

=$ 190

The equation is:
250 - (120 ÷ x)
