If itt says 4×3+6 it is 18 and it means you can either multiply first
Step-by-step explanation:
let Rinus age be R
Anu's age is equal to 20+R and 6×R
20+R=6×R
20+R=6R
Collect like terms
20=6R-R
5R=20
Divide both sides by 5
R=20/5
R=4
Therefor Rinu is 4 years while Anu is 20+4 which is 24 years
X=120
2/5-(x/300)=0
Simplify= X/300
2/5-X/300=0
Simplify=2/5
2/5-X/300=0
The left denominater is: 5
The right denominater is: 300
Step-by-step explanation:
11.3x-12 for x=5
=3(5)-12
=15-12
=3
12.45+15(n-1) for n=6
=45+15(6-1)
=45+15(5)
=45+75
=120
