Answer:

x = -7

Step-by-step explanation:

This is a multi-step equation in algebra. We are expected to isolate the given variable and find the constant value that it is equal to. In order to do this, we can follow some steps:

1x - 15 = 5x + 13 Subtract 5x on both sides of the equation.

-4x - 15 = 13 Add 15 to both sides of the equation.

-4x = 28 Divide by -4 on both sides of the equation.

x = -7

You can input this value and make sure that the answer is correct.

1(-7) - 15 = 5(-7) + 13

-7 - 15 = -35 + 13

-22 = -22

-22 equals -22, so x = -7 is the solution to the equation.

Answer:

x= -7

Step-by-step explanation:

We are given the equation:

1x-15=5x+13

We want to solve for x. Therefore, we must isolate x on one side of the equation.

First, let’s move all the terms with variables to one side. Subtract 1x from both sides.

1x-1x-15=5x-1x+13

-15= (5x-1x)+13

-15=4x+13

Next, move all the constants, or terms without variables to one side. Subtract 13 from both sides.

-15-13=4x+13-13

-15-13=4x

-28=4x

Finally, divide both sides by 4. We should divide because x is being multiplied by 4 and the inverse of multiplication is division.

-28/4=4x/4

-28/4=x

-7=x

Let’s check our solution. Plug -7 in for x and solve.

1x - 15 = 5x + 13

1(-7) - 15 = 5(-7) + 13

-7-15=5(-7)+13

-22= 5(-7)+13

-22= -35+13

-22=-22

This checks out, so we know our solution is correct.

The solution to 1x - 15 = 5x + 13 is x= -7

Answer:

Below

Step-by-step explanation:

● (3/4)×(z+7) = y

Divide both sides by (3/4)

● (3/4)÷(3/4)×(z+7) = y÷(3/4)

● 1×(z+7) = y ÷(3/4)

● (z+7) = y ×(4/3)

● z+7 = 4y/3

Substract 7 from both sides

● z+7-7 = (4y/3)-7

● z = (4y/3)-7

This equation has infinite solutions. Every time you input a value you get a different solution.

Step-by-step explanation:

The mean is 27 and the standard deviation is 4.

23 is 1 standard deviation below the mean, and 31 is 1 standard deviation above the mean.  According to the empirical rule, 68% of the population is between -1 and +1 standard deviations.

68% of 1200 is 816.

19 is 2 standard deviations below the mean, and 35 is 2 standard deviations above the mean.  According to the empirical rule, 95% of the population is between -2 and +2 standard deviations.

95% of 1200 is 1140.

Answer:

60 dollars

Step-by-step explanation:

We can write a ratio to solve

4 tickets          5 tickets

--------------  = ----------------

48 dollars      x dollars

4x = 5*48

Divide each side by 4

x = 5*48/4

x = 60

Answer:

[See Below]

Step-by-step explanation:

4 tickets equals 48 so to get the price for each ticket divide:

* 48 / 4 = 12

So then just add now:

* 48 + 12 = 60.

So the cost of 5 tickets is 60$.

Answer:

B. Dependent Events

Step-by-step explanation:

Two events are dependent if the outcome of the first event affects the outcome of the second event, so that the probability is changed.

Answer:

B. 1-third

Step-by-step explanation:

The formula for probability = Number of favorable outcomes/ Total number of outcomes

From the question, we are told that:

Owen knows he only has three pencils in his backpack, and they are all yellow. Hence, total number of outcomes = 3

He reaches into his backpack without looking and takes out a pencil.

Hence, total number of favorable outcomes = 1

What is the probability that the pencil was yellow?

Probability ( That the pencil is yellow) =

Number of favorable outcomes/ Total number of outcomes

= 1/3

Therefore, the probability that the pencil was yellow is 1/3 or one - thirds

Answer: [tex]M = 50 + 7.50 h[/tex]

Step-by-step explanation:

As per the given scenario,

Total money Christina made = (Money she made in tips) + (Per hour wage ) x (Number of hours she work in one night)   (i)

Let M is the total money she makes and h is the number of hours she works in one night.

Here, Money she made in tips = $ 50

Per hour wage = $7.50

So substitute all the values in (i), we get

[tex]M = 50 + 7.50 h[/tex]

Hence, the required function is [tex]M = 50 + 7.50 h[/tex].

Answer:

=-6x^7

Answer:

[tex]-6x^7[/tex]

Step-by-step explanation:

So when doing this equation, you multiply the numbers, which is 2 × -3, and add the exponents, which is 3 + 4, so then you get the answer, and that is [tex]-6x^7[/tex].

Answer:

[tex] x = 2.5 [/tex]

Step-by-step explanation:

Surface area of cylinder = 2πr(h + r)

Volume of cylinder = πr²h

Given that S.A = Volume of the cylinder, therefore, we have:

2πr(h + r) = πr²h

Radius (r) is given as 2.5 cm

height (h) = x cm

Input the values and solve for x

2πr(h + r) = πr²h

2πr(h + r) = πr(rh)

2(h + r) = rh (πr cancels πr)

[tex] 2(x + 2.5) = 2.5*x [/tex]

[tex] 2x + 5 = 2.5x [/tex]

Subtract 2x from both sides

[tex] 2x + 5 - 2x = 2.5x - 2x [/tex]

[tex] 5 = 0.5x [/tex]

Divide both sides by 0.5

[tex] \frac{5}{0.5} = \frac{0.5x}{0.5} [/tex]

[tex] 2.5 = x [/tex]

[tex] x = 2.5 [/tex]

The question asks us to find the a graph which represents the width of the rectangle increasing by 1 unit while the area remains constant. The best graph to model this, would be answer choice C

The graph in option 3 models the length of the new rectangle.

According to the problem,

Now if width becomes (x+1) units

∴ Length will be represented as 10/(x+1)

Now from the given options we need to find the exact graph of              f(x) = 10/(x +1)

Here if x = 4 , y =2

So the point (4 , 2) is satisfied which is only happening in the graph of option 3

Option 3 represents the correct graph

Answer:

C. [tex] (4, 0) [/tex] and [tex] (-5, 0) [/tex]

Step-by-step explanation:

Given the expression, [tex] (x - 4)(x + 5) [/tex], the x-intercepts would be the values at which the expression = 0.

Rewrite the expression as:

[tex] (x - 4)(x + 5) = 0 [/tex],

Set the first and the second factors equal to 0

[tex] (x - 4) = 0 [/tex]

[tex] x = 4 [/tex]

[tex] (x + 5) = 0 [/tex]

[tex] x = -5 [/tex]

All the values that make [tex] (x - 4)(x + 5) = 0 [/tex] are the x-intercepts of the expression.

x = 4, -5

The point form of the x-intercepts are:

[tex] (4, 0) [/tex] and [tex] (-5, 0) [/tex]

Answer:

Step-by-step explanation:

The base number is 13 dollars since you must pay it before adding hourly expenses.

Every hour, you have to pay 5.50.

So, the total cost would equal:

29.50 - (13 + 5.5h) < 29.50

Think: you have 29.50. you must pay 13 dollars before using it. it costs 5.50 for each hour. your money must be less than your total.

Hope this helped :)
