Simplify (4x − 6) − (5x + 1).
a. x +7
b. -x+7
c. x- 7
d. -x-7

Answer:

60

Step-by-step explanation:

if 20 = 12%, then x = 100%

20 = 12

x = 100

We can solve this using cross multiplication.

20*100 = 12x

2000 = 12x

166.67 = x

Answer:

x = -2

x = 2

x = ?/2

x = ?(2)

Step-by-step explanation:

For each problem you want to isolate the variable.

For x + 2 you want to move the 2 by subtracting it (since it is being added to the x) from each side. Assuming the other side of the equal sign is 0, the answer is -2.

Same thing for x - 2, isolate by adding the 2 (since it is being subtracted).

For 2x and x ÷ 2 it is a little different. If we assume the opposite side is 0, the answer will be 0 because 0 divided or multiplied by 2 will give you 0. But if the opposite side is a different number, the answer will be that number and then the respected equation for the problem (divide both sides by 2 in 2x because the x is being multiplied by the 2 and multiple both sides by 2 in the x ÷ 2 because the x is being divided by the 2).

Answer:

[tex]2w+2(w+12)=P (104)[/tex] and [tex]w=20[/tex]

Step-by-step explanation:

We know that the following equation represents the problem:

[tex]2w+2(w+12)= P[/tex]

So this means that we can do this:

[tex]4w+24= P[/tex]

We know that [tex]P[/tex] is 104. We need to fix our current equation, giving us:

[tex]4w+24=104[/tex]

We can subtract 24 to give us [tex]w[/tex] as a standalone with a coefficient.

[tex]104-24=80[/tex]

[tex]4w=80[/tex]

Then, simply divide the answer by the coefficient to give us the answer of:

[tex]80/4=20\\[/tex]

[tex]w=20[/tex]

[tex]w[/tex] is 20.

Answer:

y=4.5

Step-by-step explanation:

Student 3 determines the area of the circle correctly.

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

Given, A circle has a circumference of 50.24 feet.

We know the circumference of a circle is 2πr.

Therefore, 2πr = 50.24.

πr = 50.24/2.

πr = 25.12.

r = 25.12/3.14.

r = 8 feet.

We also know the area of a circle is πr².

= π(8)² square feet.

= 200.96 square feet.

Student 3 determines the area correctly.
