Answer:
Step-by-step explanation:
-4=9y+13-4y
combine like terms
9y-4y=5y
-4=5y+13
subtract 13 on both sides
-4-13=-17
-17=5y
divide both sides by 5
-17/5=y
since it cant reduce lower than that it stays like that.
hope this helps....
Answer:
B = 115
Step-by-step explanation:
Since A and B are supplementary, they add up to 180 degrees.
Thus, 65 + B = 180, and B = 115
AREA OF TRIANGLE = BxH/2
(4+6) x 8/2
(10) x 8/2
80/2
40cm^2
A) A=500(1+0.015)^t
b)800=500(1.015)^t
800/500=1.015^t
t=log(800/500)/log(1.015)
t=31.6 years
