5, 10 ,15
divide each by 5
1,2, 3
so the ratios should be 1,2,3
Metal 1 : divide by 150
1,2,4
Metal 2 divide by 130
1,2,3
Metal 3 divide by 310
1,2,3
Metal 4 divide by 140
1,2,3

Choice A
Answer:
x=3
Step-by-step explanation:
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
Answer:
the other number is 6350
Step-by-step explanation:
given data
difference between two numbers = 2790
smaller number = 3560
to find out
the other number
solution
we consider here larger number = x
smaller number = y
so
so difference between two number is express as
difference between two number = x - y ....................1
put here value and we get another number i.e large number
2790 = x - 3560
solve it we get
x = 6350
so the other number is 6350
