when solving an equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10​

Answer:

[tex]Average = 2.073[/tex]

Step-by-step explanation:

Given:

Time: 2.15, 2.05, 2.02

Required

Determine the average

Average is calculated as thus:

[tex]Average = \frac{\sum x}{n}[/tex]

In this case:

[tex]\sum x = 2.15+2.05+2.02[/tex]

and

[tex]n = 3[/tex]

[tex]Average = \frac{\sum x}{n}[/tex] becomes

[tex]Average = \frac{2.15+2.05+2.02}{3}[/tex]

[tex]Average = \frac{6.22}{3}[/tex]

[tex]Average = 2.073[/tex]

Answer:

B

Step-by-step explanation:

Because there's no change in x so it has to be a straight line going through the y-axis.

Also for A and C, they don't even touch y = 2 so you can easily cross those out.

Answer:

a. [tex] \frac{2}{3} [/tex]

Step-by-step explanation:

The fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex] and less than [tex] \frac{3}{4} [/tex].

How do we know this? See below how the fractions are compared together.

First, compare [tex] \frac{2}{3} [/tex] and [tex] \frac{1}{2} [/tex].

Find a common denominator for both fractions:

Common denominator of 2 and 3 would be 6. Therefore, multiply as follows:

[tex] \frac{2 \times 2}{3 \times 2} = \frac{4}{6}[/tex] and

[tex] \frac{1 \times 3}{2 \times 3} = \frac{3}{6} [/tex].

Compare the numerators. Which one is greater?

Form the calculation above:

[tex] \frac{2}{3} = \frac{4}{6} [/tex] has a numerator of 4.

.

[tex] \frac{1}{2} = \frac{3}{6} [/tex] has a numerator of 3.

Since 4 is greater than 3, therefore, the fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex].

✍️Compare [tex] \frac{2}{3} [/tex] and [tex] \frac{3}{4} [/tex].

Find a common denominator for both fractions

[tex] \frac{2 \times 4}{3 \times 4} = \frac{8}{12} [/tex] and

[tex] \frac{3 \times 3}{4 \times 3} = \frac{9}{12} [/tex]

Comparing their numerator, 8 is less than 9, therefore:

[tex] \frac{2}{3} [/tex] is less than [tex] \frac{3}{4} [/tex].

✔️We can conclude that:

[tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex], and less than [tex] \frac{3}{4} [/tex].

Step-by-step explanation:

Answer: C. 2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Begin by removing the brackets

4x + 5(-4x - b) = -16x - 5b

-(x - 2) = -x + 2

Add the two binomials together to get the third one

4x -20x - 5b - x + 2 = -17x - 8                 Combine the like terms on both sides

-17x - 5b +2 = -17x - 8                             Add 17x to both sides

-5b + 2 = - 8                                           Subtract 2 from both sides

-5b +2 -2 =- 8 -2                                     Combine    

-5b =  - 10                                               Divide by -5

b = -10/-5

b = 2

Answer:

Marcus earns 15% commission on his total sales at work.

Suppose Marcus's sales totaled $725 last week. How much did he earn in commission?

A.

$833.75

B.

$616.25

C.

$108.75

D.

$10.88

Step-by-step explanation:

Answer:

D : Obtuse

Step-by-step explanation:

A right angle is 90 degrees.

An acute and obtuse angle are found by looking at the angle between the sides being looked at.

If the angle is GREATER i.e. Angle > 90 , then it is obtuse.

If the angle is LESS THAN i.e. Angle < 90 , then it is acute.

This angle is apparently greater than 90 degrees and therefore is obtuse.

Answer:

8

Step-by-step explanation:

In order you find the answer, you must divide 5 1/3 by 2/3.

In order to do this, you have to convert 5 1/3 into an irregular fraction, by multiplying 5 by 3 and adding it to 1. You'll end up with 16/3

When dividing fractions, you multiply the first number by the reciprocal of the second. 16/3 is the number being divided, so 2/3 will be our second number. The reciprocal of 2/3 is 3/2.

16/3 x 3/2 = 8.

37.5*i

Step-by-step explanation:

4√88*√-1

4*(9.4)*i

37,7*i

Answer:

NO i do not think so because you would end with a -4 not positive because a positive times a negative is a negative so (-3,4) is not a solution.

Answer:

Sound can travel 12 miles per minute.

Step-by-step explanation:

Speed equation is distance divided by time.

So we have 1 mile per 1/12 of a minute.

Let’s write the equation.

Speed of sound = 1 / 1/12

Multiply by the reciprocal.

1 * 12 = 12.

Answer:

72.13

Step-by-step explanation:

If you bought a stock last year for a price of $79, and it has gone down 8.7% since then, how much is the stock worth now, to the nearest cent?​

Answer:

67.55 rounded to the nearest cent.

Step-by-step explanation:

The answer is 67.55 because since 100% minus 8.7% is 85.5% and 85.5% of 67.55 is 67.55 rounded.

Answer:

Option C

Step-by-step explanation:

Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,

P ∝ N

P = kN

Here 'k' is the proportionality constant

To get the value of proportionality constant,

Since, value of 10 cribs is $1320

1320 = k(10)

k = 132

Therefore, equation will be

P = 132N

Option A

If number of cribs = 6

P = 132(6) = $792

False.

Option B

For N = 22

P = 132(22) = $2904

False.

Option C

For N = 40

P = 132(40) = $5280

True

Option D

For N = 55

P = 132(55) = $7260

False

Option E

For N = 80

P = 132(80)

  = $10560

False

Option F

For N = 250

P = 132(250)

  = $33000

False

If the given options have been written correctly only one option, Option (C) is correct.

Answer:

r=144

Step-by-step explanation:

Cross multiply:

12 * 60 = r * 5

Simplifying

12 * 60 = r * 5

Multiply 12 * 60

720 = r * 5

Reorder the terms for easier multiplication:

720 = 5r

Solving

720 = 5r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-5r' to each side of the equation.

720 + -5r = 5r + -5r

Combine like terms: 5r + -5r = 0

720 + -5r = 0

Add '-720' to each side of the equation.

720 + -720 + -5r = 0 + -720

Combine like terms: 720 + -720 = 0

0 + -5r = 0 + -720

-5r = 0 + -720

Combine like terms: 0 + -720 = -720

-5r = -720

Divide each side by '-5'.

r = 144

Simplifying

r = 144

Answer:

r=144

Step-by-step explanation:

We need to find r. To do that me must make the top numbers the same.

We'll multiply

[tex] \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} [/tex]

[tex] \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} [/tex]

Since the top numbers are equal that means the bottoms are too.

So we can create the equation:

[tex]5r = 720[/tex]

Divide each side by 5

r=144
