3x+8=13x-8x. Also it’s asking me to check can you send a check too thanks

Answers

Answer 1

Answer:

x = 4 CAN I HAVE BRAINEST PLZ

Step-by-step explanation:

3x + 8 = 13x - 8x (collect like terms)

3x + 8 = 5x (subtract 3x on both sides)

8 = 2x (divide by 2 on both sides)

4 = x

CHECK

3(4) + 8 = 13(4) - 8(4)

12 + 8 = 52 - 32

20 = 20

Admission to a local aquarium is $10 for
adults and $7 for children. The aquarium
collected $6,549 from the sale of 783
tickets. Find the number of adult tickets and
children tickets that were sold.

Answers

First, let's define variables:

A = adults

C = children

Okay, now that's done, time to set up the two equations required to solve:

10a + 7c = 6549

a + c = 783

One way you can solve this is to set up the second equation to isolate a variable. For example,

a = -c + 783

Using this, we can plug it into the first equation and solve for c.

10(-c+783) + 7c = 6549

-3c = -1281

c = 427

Now, use the value of 427and plug it in either equation to solve for a.

a + 427 = 783

a = 356

356 adult tickets were sold, and 427 children tickets were sold.

Answers

Answer:

Step-by-step explanation:

jus got it right

There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have a linear equation in one-variable:

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

0.75(x + 40) = 0.7(x + 20)

75(x + 40) = 70(x + 20)

75x = 70x - 1600

x = -370

Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

e) Set this equal to the total cost

6p -3p= 38.94

f) Combine like terms

3p = 38.94

Divide each side by p

3p/3 = 38.94/3

p = 12.98

1. Factor the first equation.

7x³−11x²−14x+16

7x³−14x²+3x²−6x−8x+16

7x²(x-2)+3x(x-2)-8(x-2)

(x-2)(7x²+3x-8)

2. So this is as far as we have to go because as we can see x-2 is a factor of the equation.

3. Factor the second equation.

7x⁴+22x³+2x²+11

4. As we can see this equation isn’t factorable, so which means that this equation can’t have an exact root so which means x+3 is not a factor for the second equation.

Solve 6kx = 4kx + 8 for x.
Start by collecting the variable terms on the same side of the equation.

What is the first step?

Answers

Answer:

x = 4k

Step-by-step explanation:

6kx = 4kx + 8

The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.

2kx = 8

Next, move the 2k to the right side of the = by dividing both sides by 2k

x = 8/2k

The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.

x = 4k

Which of the following equations are true about the following parallelogram?

Answers

Answer:

A, B, E

Step-by-step explanation:

A is true since the sum of the measures of two consecutive angles of a parallelogram is 180 deg.

B is true since opposite angles of a parallelogram are congruent.

C is false since that equation gives x = -1, but x cannot equal -1 since that would make angle 3x - 12 have a negative measure.

D is false for the same reason as choice C.

E is true since x = 20 is the solution of the equations in choices A and B.

Tiffany ate 1/4 of a pizza. If there were 16 slices of pizza to begin with, how many slices did Tiffany eat?

" Fraction is a representation of a part of whole object which is divided into equal parts."

According to the question,

Total number of pizza slices = 16

Part of pizza ate by Tiffany = 1 / 4
