Answer: 10
No matter if you simplify the square roots or not before multiplying, you get 10.
Divide 309 by 3:
309 / 3 = 103
for the lower number subtract 1: 103 -1 = 102
for the higher number add 1: 103+1 = 104
The 3 numbers are 102, 103, 104
The middle number is 103.
The answer is C.
M= movie cost
v= video cost
Create two equations with the given information. Solve for one variable in equation one. Use that answer to substitute into equation two.
2m+12v=$44
5m+3v=$29
Solve for one variable in equation 1:
2m+12v=44
Subtract 12v from both sides
2m=44-12v
Divide both sides by 2
m=(44-12v)/2
Substitute m answer in equation two:
5m+3v=$29
5((44-12v)/2)+3v=29
(220-60v)/2+3v=29
Multiply everything by 2 to eliminate the fraction
(2)(220-60v)/2+(2)(3v)=(2)(29)
220-60v+6v=58
220-54v=58
Subtract both sides by 220
-54v= -162
Divide both sides by -54
v= $3.00 cost per video
Substitute v value to find m value:
2m+12v=$44
2m+12(3.00)=44
2m+36=44
Subtract both sides by 36
2m=8
Divide both sides by 2
m=$4.00 cost per movie
Check:
5m+3v=$29
5(4.00)+3(3.00)=29
20.00+9.00=29
29=29
Hope this helps! Please mark me as brainliest if it does. :)
Answer:
The correct answer is the last one. It is the only equation with a negative slope. The slope in the picture is negative and therefore it is the only possible answer.
