Answer:
Q1.Let's solve your equation step-by-step.
2(x+3)=5x+6−3x
Step 1: Simplify both sides of the equation.
2(x+3)=5x+6−3x
(2)(x)+(2)(3)=5x+6+−3x(Distribute)
2x+6=5x+6+−3x
2x+6=(5x+−3x)+(6)(Combine Like Terms)
2x+6=2x+6
2x+6=2x+6
Step 2: Subtract 2x from both sides.
2x+6−2x=2x+6−2x
6=6
Step 3: Subtract 6 from both sides.
6−6=6−6
0=0
Answer:
All real numbers are solutions.
Q2.x−3=2x−3−x
Step 1: Simplify both sides of the equation.
x−3=2x−3−x
x+−3=2x+−3+−x
x−3=(2x+−x)+(−3)(Combine Like Terms)
x−3=x+−3
x−3=x−3
Step 2: Subtract x from both sides.
x−3−x=x−3−x
−3=−3
Step 3: Add 3 to both sides.
−3+3=−3+3
0=0
Answer:
All real numbers are solutions.

Step-by-step explanation:
True, when multiplying variables you add the exponents.
88 degrees is the answer. You would start by setting up the equation as (5x+7)+(8x+8)+(3x+5)=180 because all angles of a triangle have a sum of 180 degrees. From there you combine like terms which would leave the answer of being 16x+20=180 then you subtract the 20 from 180 to get x by itself. Then that would leave you with 16x=160 then you divide both sides by 16 to get x=10. From there you plug 16 into the x in the planetarium equation which is 8(10)+8 which equals 88 degrees
14/15 is .93333333333333333 and 7/8 is .875 so 14/15 is
bigger
