Answer:
a: 300cm
b: 7m
c 450cm
d: 95 m
Step-by-step explanation:
if the given value is in meters multiply by 100
if the given value is in cm divide by 100
8y - 6 = 5y + 12
- 5y - 5y
3y - 6 = 12
+ 6 + 6
3y = 18
3 3
y = 6

Answer:
10, 19 and 57
Step-by-step explanation:
let the first number be a, the second be b and the third be c
a+b+c=86
the second number is 9 less than the first
a=b+9------i
b=a-9
the third number is 3 times the first
c=3a------ii
a=c/3
therefore
b+9=c/3
c=3(b+9)
b+9+b+3(b+9)=86
b+9+b+3b+27=86
collecting like terms
5b=86-(27+9)
5b=86-36
5b=50
therefore
b=10
recall i to solve for a
a=b+9
a=10+9
a=19
recall ii to solve for c
c=3a
c=3*19
c=57
