Hi!
The table above is showing how to plug in a variable to x. For an example,
5x - 3 =?
when x= 4 would equal 17. How we would get this is substitute x with 4 and use our order of operations.
5(4) - 3 = 20 - 3 =  17
To get 68, we would do this in reverse. We would add 3 to both sides to eliminate the -3 to have a remainder of
5x  =  71
Divide both sides by five to solve for x.
x = \frac{71}{5}
We can also check our math and plug in 17/5 into x
5( \frac{71}{5} ) - 3 =71 - 3 = 68

Answer:

£24,980

Step-by-step explanation:

total pay = monthly salary + percent of annual profit + £250 bonus

monthly salary = £1,850

annual salary = 12 × £1,850 = £22,200

agency income = £356,000

agency costs = £280,000

annual profit = income - costs = £356,000 - £280,000 = £76,000

percent of annual profit = 3% × £76,000 = 0.03 × £76,000 = £2,280

£250 bonus = 2 × £250 = £500

total pay = monthly salary + percent of annual profit + £250 bonus

total pay = £22,200 + £2,280 + £500

total pay = £24,980

Will give brainliest!!! hurry up and solve it plzz​

Answer:

8

Step-by-step explanation:

we can say that AD is congruent to DC

so your equation for x is: 4x - 1 = 2x

solve this to get x = 0.5

plug x into and equation and multiply you answer by 2 to find the hypotenuse of triangle ABC and DEF

4(0.5) - 1 = 1

hypotenuse: 1 x 2 = 2

since we know x is 0.5, plug this into 4x + 1 to find the length of the leg FE,

4(0.5) + 1 = 3

In the diagram, it shows that the legs of triangle are congruent

this means that FE, ED, BA, and BC are all congruent

since we know FE is 3, we know that all the other sides are 3 as well

this means that the perimeter of the triangle is: leg + leg + hypotenuse

so 3 + 3 + 2

the perimeter is 8
