Answer: x = 0
<u>Step-by-step explanation:</u>
4(7 - 3x) = 7(4 - 2x)
28 - 12x = 28 - 14x <em>distributed</em>
28 + 2x = 28 <em>added 14x to both sides</em>
2x = 0 <em>subtracted 28 from both sides</em>
x = 0 <em>divided both sides by 2</em>

Answer:
profit=20%
Step-by-step explanation:
profit%=sp-cp/cp×100%
=1500-1250/1250×100
=250/1250×100
=20%
To solve this you would use the pythagorean theorem since the brace is making the frame look like two right triangles. The theorem states that for a triangle with a right angle, A^2+B^2=C^2. A and B are the sides of the frame and C is the brace which is like the hypotenuse of the triangle. It doesn't matter which side is A or B so you can put 6 or 8 in place of either in the equation. 6^2+8^2=C^2. If you simplify this it equals 36+64=C^2, which then simplifies to 100=C^2. Then you take the square root of both sides (what number multiplied by itself = the number you are trying to get, in this case, 100). So then you get C=10 because 10x10=100. So the length of the diagonal brace is 10ft.
Answer:
Should be D: Area multiplied by 1/3
Step-by-step explanation:
So since your radius is being multiplied by 1/3, so is your area. I think.
