Answer:

$15 And $10

Step-by-step explanation:

Let T-shirt’s be x and pants be y.

Firstly 5 T-shirts plus 3 pairs of pants cost $105

That’s

5x + 3y = 105

The next day 4 T-shirts and 2 pairs of pants cost $80.

That’s

4x + 2y = 80

Thus we have

5x + 3y = 105

4x + 2y = 80

Multiply equation one by 4 and equation two by 5

We have

20x + 12y = 420

20x + 10y = 400

Subtract equation 2 from 1

We’re left with

2y = 20

Divide both sides by 2

y = 20/2

y = 10

Now substitute 10 for y into any of the equations to get x.

Using equation one

We have

5x + 3 x 10 = 105

5x + 30 = 105

Subtract 30 from both sides

5x + 30 - 30 = 105 - 30

5x = 75

Divide both sides by 5

x = 75/5

= 15

Therefore each T-shirt cost $15 and each pant costs $10

antiseptic1488 [7]

Option B is correct.

John wants to find the center of a wall so he can hang a picture. He measures the wall and determines it is 65.25" wide.

Here, 65.25" is Quantitative, continuous

There are two types of quantitative data or numeric data: continuous and discrete.

As a general rule, counts are discrete and measurements are continuous. A continuous data can be recorded at many different points (length, size, width, time, temperature, etc.)

So, option B is the answer.

Examine the fraction 3+2i4−2i. Which expression is the first step to simplify the fraction? 3+2i4−2i⋅3−2i3−2i
umka2103 [35]

Answer:

The correct answer is the last option.

Step-by-step explanation:

When you have a fraction with complex numbers, the first step to simplify is to multiply up and down the conjugate of the denominator, this will eliminate the complex part of the denominator, and in this way you can separate the expression in its real and complex part.

For the expression:

\frac{3 + 2i}{4-2i
}

The denominator conjugate is 4 + 2i

When multiplied, the denominator is:

4 ^ 2 -4i ^ 2 = 16 -4 (-1) = 20
