The answer is 12,825 kg because if one car equals 1425 kg and a car carrier can hold 9 cars, then you just have to multiply 1425 by 9 to get 12,825
3x - y > -1
3x - 3x - y > -1 - 3x
-y > -1 - 3x
y > 1 + 3x
2x + y > 5
2x - 2x + y > 5 - 2x
y > 5 - 2x
1 + 3x > 5 - 2x
<u> + 2x + 2x</u>
1 + 5x > 5
<u>- 1 - 1</u>
<u>5x</u> > <u>4</u>
5 5
x > 0.8
1 + 3(0.8) > 5 - 2(0.8)
3(0.8) - y > -1
2.4 - y > -1
<u>- 2.4 - 2.4</u>
-y > -3.4
y > 3.4
(x, y) > (0.8, 3.4)
Step-by-step explanation:
have nice day
your answer
2.23 is the cost of each shirt
I did 8.92 / 4 = 2.23
If t/5 = 7/r
and you flipped 7/r to r/7... flip t/5 too.
If t/5 = 7/r, then 7/r = 5/t
5/t should be your answer
hope this helps
