Hitman42 [59]

Answer:

a=3, c=-4, x=8

Step-by-step explanation:

5=4a-7

4a-7=5

4a=5+7

=12

a=12÷4

=3

3-8c=35

-8c=35-3

=32

c=-32÷8

=-4

-1/2x-7=-11

-1/2x=-11+7

=-4

x=4÷1/2

=4/1×2/1

=8

Find three consecutive even integers such that six times the sum of the first and the third is twenty - four greater than eleven
dedylja [7]

Answer:

1st = 22

2nd = 24

3rd = 26

Step-by-step explanation:

1st = x

2nd = x +2

3rd = x + 4

6(x + x + 4) = 24 + 11(x + 2)

6(2x + 4) = 24 + 11x + 22

12x + 24 = 46 + 11x

x + 24 = 46

x = 22

x + 2 = 24

x + 4 = 26

Answer:

x = 4

m∠EFH = 21°

m∠EFG = 83°

Step-by-step explanation:

We know that m∠EFH + m∠HFG will be equal to m∠EFG.

Since we know the values of each, we can make the equation:

5x + 1 + 62 = 18x + 11

Let's solve for x by isolating it on one side.

Combine like terms:

5x + 63 = 18x + 11

Subtract 11 from both sides:

5x + 52 = 18x

Subtract 5x from both sides:

52 = 13x

Divide both sides by 13:

x = 4

Now that we know the value of x, we can substitute it inside the formulas for m∠EFH and m∠EFG.

m∠EFH:

5x+1\\\\5(4)+1\\\\20+1\\\\21

m∠EFG:

18x+11\\\\18(4)+11\\\\72+11\\\\83

Hope this helped!
