Step-by-step explanation:
<u>Step 1: Define Equation</u>
2(x + 4) = 4x + 3 - 2x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 2x + 8 = 4x + 3 - 2x + 5
- Combine like terms: 2x + 8 = 2x + 8
- Subtract 8 on both sides: 2x = 2x
- Divide 2 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ x = infinite amount of solutions
Answer:
10.8 centimeters :]
Step-by-step explanation:
1.2 x 9 = 10.8 centi meters
1.2 x 1=1.2
1.2 x 2=2.4
1.2 x 3=3.6
1.2 x 4=4.8
1.2 x 5=6
1.2 x 6=7.2
1.2 x 7=8.4
1.2 x 8=9.6
1.2 x 9=10.8

Answer:
90°
Step-by-step explanation:
It looks slightly obvious, but here's the complicated explanation.
Converse of the Consecutive Interior Angles Theorem. Solve.
x+96+x+96=180
Simplify.
2x+192=180
Subtraction Property of Equality (subtract 192 from both sides to isolate 2x).
2x=-12
Division Property of Equality (divide both sides by 2 to isolate x).
x=-6
Now that you have your x value, plug it in into your bolded equation.
x+96
-6+96
Simplify.
90°
I’m pretty sure it’s the first one! Goodluck :)
