Well first you round to the nearest whole number so 15.92 is rounded to 16 and 0.85 is rounded to 1 and then you add or subtract. So if u add you get 17 if u subtract you get 15
The question gives you 3.5 hours for the first one, $14 for rental(which you solved in the previous problem) for the second one, + $7(also solved in previous problem) for the third one. Solving the equation will give you 56 for the fourth blank. Solving and dividing by 2, you get 28 for the fifth blank.
Answer:
4 is C
I'm still figuring out 3 sorry
Step-by-step explanation:
Assuming that both triangles are an exact copy of one another, it is safe to assume that 3y-7 is equal to 41. Set up an equation
3y-7=41
Add 7 to both sides
3y=48
Divide both sides by 3
y=16
Now to find PN.
Based on what we know, we can assume that MP = PN. Let's make some equations!
MP = 17x-8 PN = 11x+4
17x-8 = 11x+4
Subtract 11x from both sides
6x-8 = 4
Add 8 to both sides
6x = 12
Divide by 2
x=2
Substitute 2 in for x in the equation for PN
11(2)+4
Multiply 11 by 2
22+4 = 26
PN = 26
Since they both have 3x terms subtract the second from the first to get rid of the x terms...
3x+2y=10
-3x+y=-13
__________
3y=-3
y=-1, which makes 3x+2y=10 become: 3x-2=10 so
x=4
So the solution is the point (4, -1)
