Answer:
total number of parts of a 2:5 ratio are 7 as 2+5 = 7
let us assume are number to be 49
the first part will be 49/7 × 2 = 14
the second part will be 49/7 × 5 = 35
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
(a) 1/12
(b) 3/12=1/4
(c) 2/12 = 1/6
(d) 3/12 + 3/12 = 6/12 = 1/2
I think it’s right ???
You could wash 75 cars at this rate because 45/3 equals 15. You would multiply 5 by 15 and get 75.
