Answer:
£83.70
Step-by-step explanation:
→ First step is to find the amount of hours it takes for one builder
We know it takes 5 builders hours so 1 builder would take 5 ×
which is
hours so it takes one builder 17.5 hours to builder a wall
→ Now we know how long one work takes we need to find out the time for 2 builders
1 builder = 17.5 hours
2 builders = 17.5 ÷ 2 = 8.75 hours
So 2 builders take 8.75 hours
→ We know that each builder is paid £9.30 for each or part hour they work so
9.30 hourly pay rate × 9 hours work of work = £83.70
Each worker will be paid £83.70
Answer:
x=3
Step-by-step explanation:
The approach is not very different from regular fractions.
You have to get to a common denominator to be able to add them.
10 is a good denominator (multiply the denominators).
multiply the first term by 5, and the second one by 2:
7x + 9 = 30
7x = 30 - 9
x = 3
