Answer:
c
Step-by-step explanation:
formula l=PRT
bring PT to right side we get
l/PT = R
or
R=l/PT
Green family=15n
n is number of hours
Bryant family= 40x
x is number of hours
15n+40x=1450L
n+x=55
use simultaneous equations
(15n+40x=1450)-(15n+15x=825)
25x=625
x=25hours
n=55-x
n=55-25=30hours
Answer:
find k by putting -3 where there is x than -6 on g(x)
Step-by-step explanation:
g(x)=3k-2x²
-6=3k-2(-3)²
-6=3k-18
-6+18=3k
12=3k
12÷3=3k÷3
4=k
0.70 the 9 is in the hundredth place so you use the 8 in the thousandths place to round it up to 0.70
Could you give the "given" angle measures?
