Answer:
Step-by-step explanation:
we see that y = -3x-3
substitute that into the other equation to get
-3x-3 = 2x+7
-5x = 10
x = -2
so, y = -3(-2)-3 = 3
check to make sure (-2,3) solves both equations.
Im not sure if im correct but I think the answer is 82 hours.
Answer:
first blank 39, second 9/39 i think, and third 351
Step-by-step explanation:
i haven't done something like this in a long time so i dont know if its completely correct or correct at all
Given diameter 2cm
Find the area of a circle
the formula for area of a circle
A = pi r^2
the diameter is the radius times two
so to find the radius given the diameter 2/2 = 1
radius is 1cm
pi is ~3.14
A = (3.14) * (1)^2
A = (3.14) * 1
A = 3.14
Hope this helps :)
Setting it up, we have Dan + Bret + Maria all saving 600.00
Dan = 2B
Bret = B
Maria = B+60
2B + B + B + 60 = 600
4B = 540
B = 135
Dan = 2(135) = 270
Brett = 135
Maria = 135 + 60 = 195
