Answer:
5.5
Step-by-step explanation:
So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.
So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.
Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
Now we have 11-5.5=?
so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
We need to find a number that satisfies the equation and answer
so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
5.5 satisfies the equation, therefore is the answer

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
Answer:
Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
Answer:
Grace is right
Step-by-step explanation:
3(2-x)-2(6x-8)=
so:
3×2 is 6
3×(-x) is -3x
-2×6x is -12x
-2×(-8) is 16 because -×- equals +
3(2-x)-2(6x-8)
=6-3x-12x+16
= -15x+22
Well now she has $4.25 lol. She had $4 then, now she has $4.25.
