Please help out and if you know help me show work ??
Ghella [55]

Answer:  14

<u>Step-by-step explanation:</u>

Consecutive even numbers would be {2, 4, 6, 8, 10, ...}

Let x represent the smallest number, then x + 2 is the middle number and x + 4 is the largest number.

1st number: x

2nd number: x + 2

3rd number: x + 4

1st number + 2nd number + 3rd number = Sum

      (x)        +      (x + 2)       +      (x + 4)      =  48

                                                      3x + 6   =  48

                                                      3x          = 42

                                                        x           = 14

1st number: x           ⇒ x = 14

2nd number: x + 2   ⇒ 14 + 2 = 16

3rd number: x + 4    ⇒ 14 + 4 = 18

<u>Check:</u>

14 + 16 + 18 = 48 \checkmark

andreyandreev [35.5K]

Answer:

<u>Cost = 25 + 50h</u>

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber​.

what will be the cost for 8 hours of work? 10 hours of work?​

=======================================================

A plumber charges $25 for a service call plus $50 per hour

<u>Cost = 25 + 50h</u>

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

<u>Cost = 25 + 50* 8 = $425</u>

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

<u>Cost = 25 + 50 * 10  = $525</u>
