Andres works 20 hours per week at a part-time job. His original pay rate was $10.00 per hour, but he recently received a pay raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y=20(10+x). If Andres earned $210 last week, what was the amount of Andres' raise per hour?

i need work shown pls

10 + 10 so y would equal 10

Step-by-step explanation:

.

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
