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:the third one
Step-by-step explanation:
just time how much months,weeks, and years, for each amount
Drainage started at 12th minute & finished at 15th minute
So, total time taken = 15-12 = 3 minute.
So, your final answer is 3 minute.
Hope this helps!
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3x2 + 2x) - 1) - (x2 - 3x + 4)
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2+5x-5
The first term is, 2x2 its coefficient is 2 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 2 • -5 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is 5 .
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2x2 + 5x - 5
brainliest plz tried rlly hard on this
(8z - 10) ÷ (-2) + 5(z - 1) is equal to "Z"
- - Final answer: Z<span />
