Plzzz Help!!! I really need it

x = 16

y = 140

Step-by-step explanation:

Since angles on a straight line add to 180°,

(8x + 12) + (3x-8) = 180

8x + 3x + 12 - 8 = 180

11x + 4 = 180

11x = 176

x = 16

Due to the Alternate Interior Angles Theorem,

y = 8x + 12

Substituting 'x=16' into 'y=8x+12':

y = 8(16) + 12

= 128 + 12

= 140

Hope this helps and be sure to have a wonderful time ahead at ! :D

step-by-step explanation:

6x9

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
