what is the percent change from 50 to 22

Answer:

- 20

Step-by-step explanation:

Step 1:

10 - 2v = - 5v - 50      Equation

Step 2:

10 + 3v = - 50    Add 5v on boh sides

Step 3:

3v = - 60      Subtract 10 on both sides

Step 4:

- 60 ÷ 3      Divide

Answer:

v = - 20

Step-by-step explanation:

The larger the denominator the smaller the fraction.

Answer:

x = -6

Step-by-step explanation:

Answer: x=-6

Step-by-step explanation:

Given

2x+5=x-1

Subtract 5 on both sides

2x+5-5=x-1-5

2x=x-6

Subtract x on both sides

2x-x=x-6-x

x=-6

Answer:

(−8,0)∪(0,∞)

Step-by-step explanation:

This is composition, which I'm going to assume you've covered (sorry if I use any weird terms because of that).

So, anyway, (f/g)(x) is basically [tex]\frac{f(x)}{g(x)}[/tex].

In this case, the answer would be [tex]\frac{\frac{1}{x} }{\sqrt{x+8} }[/tex]

I'm going to assume we're using the real number system.

In that case, x can't be less than 0 (can't even be equal to because divide by zero error

So, [tex]\sqrt{x+8} > 0[/tex]

Solve for x by squaring.

[tex]\sqrt{x+8} > 0[/tex]

[tex]x > -8[/tex]

However, in the numerator, there is 1/x. A number divided by 0 is undefined. So, x has to be greater than -8, and it can't be 0.

So, with that, the interval notation is like this.

(−8,0)∪(0,∞)

Answer:

1332.04

Step-by-step explanation:

C=2πr=2·π·212≈1332.03529

Answer:

1332.035 millimeters

Step-by-step explanation:

If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π.  π is roughly equal to 3.14.  You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Answer: B

Step-by-step explanation:

The question asks for [n≥-5] to be true, which means any value that is greater or equal to -5 will be considered.

A. {-5, -5.5, -6}

-5 TRUE

-5.5 FALSE

-6 FALSE

B. {-5, -4.5, -3}

-5 TRUE

-4.5 TRUE

-3 TRUE

C. {-6, 0, 5}

-6 FALSE

0 TRUE

5 TRUE

D. {-6, -7, -8}

-6 FALSE

-7 FALSE

-8 FALSE

As shown above, we can clearly see that Set B is the set that makes the inequality true.

Answer:

The variable, g, represents

✔ the number of grapes Graciella had

.

The equation that correctly models the problem is

✔ g/6 = 16

.

To undo what has been done to the variable,

✔ multiply by 6

on both sides of the equation.

The solution of the equation is

✔ g = 96

.

Check the solution by substituting

✔ 96

in for g and simplifying.

The solution of the equation will be g = 96.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

The variable, g, represents the total number of grapes that Graciella had.

The equation that correctly models the problem is:

g/6 = 16

To undo what has been done to the variable, we can multiply both sides of the equation by 6:

g = 6 x 16

g = 96

Therefore, Graciella had 96 grapes.

To check the solution, we substitute 96 for g in the original equation:

g/6 = 16

96/6 = 16

16 = 16

The equation is true, so our solution of g = 96 is correct.

Answer:

22 and 46

Step-by-step explanation:

let

one number is x

another is 2x+2

now 2x+2+x=68

or, 3x+2=68

3x=66

or x=66/3=22

so one number is 22 and another is (22X2+2)=46

Answer:

This means we need 3 chocolate chips and 4 peanut butter in each bag for a total of 7 cookies in each bag

Step-by-step explanation:

Find the prime factors of each number

Chocolate chips 18 = 3*6 = 3 * 2*3

Peanut butter  24 = 4*6 = 2*2*2*3

We want to fill the greatest number of bags so cancel the like factors

Chocolate chips 18 = 3*6 = 3

Peanut butter  24 = 4*6 = 2*2 =4

This means we need 3 chocolate chips and 4 peanut butter in each bag for a total of 7 cookies in each bag
