Answer:
7.7
Step-by-step explanation:
we basically follow the BEDMAS rule
1st we workout the bracket (7-2)=5
2nd the exponent 3^2=9
3rd the multiplication (7-2) . 4 = 5 . 4 = 20
4th addition 9+20=29
5th step is subtraction 29-6=23
the final step is dividing 23 by 3, which will become 7.7
6y + 12 = 3y - 3
Subtract 3y on both sides
3y + 12 = -3
Subtract 12 on both sides
3y = -15
Divide by 3 on both sides
y = -5
Put the equation in Photo math
Answer:
24 hours
Step-by-step explanation:
If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.
By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall
