Which value(s) of x makes the following equation true? 2x + 3= 2(x + 5) - 7​

Answer:

X^2 = 0 - 125

X^2 = -125

x = [tex]\sqrt{-125}[/tex]

x = [tex]-5\sqrt{5}[/tex]

Answer:

Part-to-part ratios provide the relationship between two distinct groups. For example, the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol.

Part-to-whole ratios provide the relationship between a particular group and the whole populations (including the particular group). For example, 3/5 of the students in the class are girls, or the mixture is 40% rye grass (40% is equivalent to saying 40 of every 100 parts).

Answer: A

Answer: A

Step-by-step explanation:

Answer:  13

Step-by-step explanation:

10x+8=12x−18

Step 1: Subtract 12x from both sides.

10x+8−12x=12x−18−12x

−2x+8=−18

Step 2: Subtract 8 from both sides.

−2x+8−8=−18−8

−2x=−26

Step 3: Divide both sides by -2.

−2x - 2

=

−26-2

So , x=13

Answer: [tex]x[/tex] = 13

1. 10[tex]x[/tex] + 8 − 12[tex]x[/tex] = 12[tex]x[/tex] − 18 − 12[tex]x[/tex]

  −2[tex]x[/tex] + 8 = −18

2. −2[tex]x[/tex] + 8 − 8 = −18 − 8

   −2[tex]x[/tex] = −26

3. Split both sides by 2.

x = 13

Answer:

The key to solving two-step equations is identifying the inverse operations that you need to perform. Thinking of an equivalent expression may help you in this process. Also, be sure to go back and check your solution for accuracy.

Example:

Solve: -18 - x = 22.

Do you know what you would have to do to the equation to solve for x?

Solution:

If we think, "-18 - x" is the same as "-x - 18," we can see that x has been multiplied by -1, and, then, 18 has been subtracted from it. To solve for x, we must undo each of these operations. We add 18, and then divide by -1. Now, let's look at the solution to this equation.

-18 - x = 22 • Original equation.

-18 - x + 18 = 22 + 18 • Add 18 to both sides.

-x = 40 • Complete the addition.

[tex]\frac{-x}{1}[/tex]= [tex]\frac{40}{1}[/tex] • Divide both sides by -1.

x = -40 • Complete the division.

Let's check the solution of -40.

-18 - (-40) = 22 • Substitute the value into the equation in parentheses!

-18 + 40 = 22 • Subtracting a negative is the same as adding a positive.

22 = 22 • Complete the addition.

hope this helps!

Answer:

Olivia-2.25

Step-by-step explanation:

Olivia runs faster than Maggie.

Olivia runs 2.22 miles/hour faster than Maggie.

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values are given using this formula.

We have,

To compare the speeds of Maggie and Olivia, we can calculate their respective rates using the formula:

rate = distance/time

For Maggie:

distance = 1/4 mile

time = 1.3 minutes

rate = (1/4) / 1.3 = 0.1923 miles/minute

For Olivia:

distance = 2/3 mile

time = 2.9 minutes

rate = (2/3) / 2.9 = 0.2293 miles/minute

Therefore, Olivia runs faster than Maggie.

To find out how much faster Olivia runs per hour, we can convert her rate to miles per hour:

0.2293 miles/minute x 60 minutes/hour x 60 seconds/minute

= 13.758 miles/hour

Similarly, we can convert Maggie's rate to miles per hour:

0.1923 miles/minute x 60 minutes/hour x 60 seconds/minute

= 11.538 miles/hour

The difference in their speeds is:

13.758 - 11.538

= 2.22 miles/hour

So,

Olivia runs 2.22 miles/hour faster than Maggie.

Thus,

Olivia runs faster than Maggie.

Olivia runs 2.22 miles/hour faster than Maggie.

v=5  

Step-by-step explanation:

are u asking to solve for v

well if so

9/3=3

v+3=8

subtract 3 both sides

v=5  

Answer:

V = 15

Step-by-step explanation:

v + 9 / 3 = 8

3(v+9) / 3 = 8 x 3

v + 9 = 24

v + 9 - 9 = 24 - 9

v = 15

Answer:

x : y = 9 : 13

Step-by-step explanation:

Given that

3x - y : x + 2y = 2 : 5

Express the ratio in fractional form, that is

[tex]\frac{3x-y}{x+2y}[/tex] = [tex]\frac{2}{5}[/tex] ( cross- multiply )

5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )

15x - 5y = 2x + 4y ( subtract 2x from both sides )

13x - 5y = 4y ( add 5y to both sides )

13x = 9y ( divide both sides by 13 )

x = [tex]\frac{9}{13}[/tex] y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = [tex]\frac{9}{13}[/tex] , that is

x : y = 9 : 13

Problem 1

-----------------------

Explanation:

The formula we'll use is

P(A or B) = P(A) + P(B)

which only works if A and B are mutually exclusive events.

P(A or B) = P(A) + P(B)

P(A or B) = 7/20 + 7/20

P(A or B) = (7+7)/20

P(A or B) = 14/20

P(A or B) = (7*2)/(10*2)

P(A or B) = 7/10

=========================================================

Problem 2

-----------------------

Explanation:

We'll use the same formula as the previous problem.

P(A or B) = P(A) + P(B)

P(A or B) = 3/10 + 9/20

P(A or B) = 6/20 + 9/20

P(A or B) = (6+9)/20

P(A or B) = 15/20

P(A or B) = (3*5)/(4*5)

P(A or B) = 3/4

=========================================================

Problem 3

-----------------------

Explanation:

We'll use the same formula as the previous problem.

P(A or B) = P(A) + P(B)

P(A or B) = 7/20 + 1/4

P(A or B) = 7/20 + 5/20

P(A or B) = (7+5)/20

P(A or B) = 12/20

P(A or B) = (4*3)/(4*5)

P(A or B) = 3/5

=========================================================

Problem 4

-----------------------

Explanation:

This time we're asked to find P(A and B), but since the two events are mutually exclusive, this means the probability of both occurring is 0.

Mutually exclusive events cannot happen simultaneously.

An example would be flipping heads and tails at the same time on the same coin.

The info about P(A) and P(B) is not relevant.

For example, 0.56565656... is equivalent to 56/99

Any time you have a repeating pattern in the decimal digits, the number can be written as a fraction of two integers. Any repeating decimal is rational.

Step-by-step explanation:

A(-4,2)=A'(-4,-2)

B(4,7)=B'(4,-7)

C(5,1)=C'(5,-1)

The average time for each leg of the race is 58.38 seconds.

Given is the question as shown in the image attached.

We can write the average time as -

t{avg} =  {56.81 + 59.22 + 57.39 + 60.11)/4

t{avg} = 58.38 seconds

Therefore, the average time for each leg of the race is 58.38 seconds.
