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
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:

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:

Let's solve for x by isolating it on one side.
Combine like terms:

Subtract 11 from both sides:

Subtract 5x from both sides:

Divide both sides by 13:

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

m∠EFG:
