Answer: £ 81.38
Step-by-step explanation:
Given: On Monday,
5 builders took
hours ( i.e.
hours ) to build a wall.
On Tuesday, only 2 builders were available.
As workers are inversely proportional to the time if the job remains constant.
Inverse variation equation : 
Let x be the time taken by 2 builders, then


So, 2 builders will take 8.75 hours.
Each paid £9.30 for each hour.
Then, each builder will be paid for the work completed on Tuesday = £9.30 x 8.75
≈ £ 81.38
Hence, each builder will be paid £ 81.38 for the work completed on Tuesday .

The algebraic expression of the phrase " The sum of square of c and d" is equal to adds the square of number c to the number d

The algebraic expression of the phrase " The sum of square of c and d increased by twice their product" is equal to

Answer:
The number of miles/the number of hours
Step-by-step explanation:
If the number of hours is not equal to 1, multiply the numerator and denominator by the inverse of the number of hours.
For example, 10 (miles)/2 (hours)
The inverse of 2 is 1/2, so --> the new equation is 10/2 * 1/2 / 1/2 or
10* 1/2 and 2 * 1/2
When multiplied out, this leads to 5/1 or 5 miles per hour
