Answer:
Step-by-step explanation:
Let B be the number of black cars and S the number of silver.
We know that B/S = 7/4
We also know that B - S = 12
Rearrange the first: B = 7S/4
B - S = 12
7S/4 - S = 12
7S - 4S = 48
3S = 48
S = 16
B/S = 7/4
B/16 = 7/4
4B = 112
B = 28
B + S = 44 cars
I can't add the tape diagram here, but show two ribbons (tapes) for each car color and drawn so one can see the relative numbers of each.
Answer:
(x:21,30,39,48)(y:7,10,13,16)
Step-by-step explanation:
For an inverse, the x value becomes the output and the y values becomes the input
(x:21,30,39,48)(y:7,10,13,16)
I think the answer is false✨
We have to find x.
5x + 9 = 7x + 3
6 = 2x
3 = x
Plug 3 for x to find the angle.
7x + 3 -> 7(3) + 3 -> 21 + 3 = 24
One angle is 24, and the other is 90, so to find <C you do this:
<C + 24 + 90 = 180
<C = 66
5*8=40=80%
0.5*4=2=4%
40+2=42
42/50=42:50=21:25
7.5*90=67.5
0.75*6=4.5
67.5+4.5=72
72/75=72:75=24:25
21:25,24:25
b is better
