What is the solution to the system?

y = 4x + 20
8x - 2y = -20

Answers

Answer 1

Answer:

-no solution-

Step-by-step explanation:

When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.

you plug in that variable to the other equation

8x - 2(4x + 20) = -20

and then you just solve the equation from there.

8x - 8x + 20 = -20

but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.

Which fractions have a LCD of 30? A. 3/4 1/7 16 B.2/3 1/5 1/15 C. 2/15 1/4 1/3 D. 2/3 1/5 1/6

Answers

Answer:

1/5, 1/6 and 1/15

Step-by-step explanation:

Multiples of 15 are 30, 45, 60, 75, 90. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6, and 1/15 is 30.

The fractions with LCD of 30 are D. 2/3, 1/5 and 1/6.

What is LCD?

LCD, which is the abbreviated form for Least Common Denominator, is the lowest of all the common multiples of the denominators for a set of fractions.

We need to find the set of fractions with LCD as 30.

A. 3/4, 1/7 and 1/6

The denominators are 4, 7 and 6.

30 is not a multiple of 4 as well as 7.

So this set is not the answer.

B. 2/3, 1/5 and 1/15

Denominators : 3 and 5

Multiple of 3 = 3, 6, 9, 12, 15, ......

Multiples of 5 = 5, 10, 15, ......

Multiples of 15 = 15, 30, .....

15 is the LCD.

C. 2/15, 1/4 and 1/3

Denominators = 15, 4 and 3

Again 30 is not a multiple of 4.

D. 2/3, 1/5 and 1/6

Denominators = 3, 5 and 6

Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, .......

Multiples of 5 = 5, 10, 15, 20, 25, 30, ......

Multiples of 6 = 6, 12, 18, 24, 30, .......

LCD of three fractions = 30

Hence the set of fraction is D. 2/3, 1/5 and 1/6 has LCD equals 30.

what is 7/12 x 3 as a fraction in simplest form

Answers

Answer:

7/4

Step-by-step explanation:

use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator

The solution to the product of the fractions is 7/4

How to evaluate the product of the fractions

From the question, we have the following parameters that can be used in our computation:

7/12 * 3

Express 3 as 3/1

So, we have

7/12 * 3 = 7/12 * 3/1

Evaluate the products of 7 and 3

So, we have

7/12 * 3 = 21/12

Divide 21 and 12 by 3

7/12 * 3 = 7/4

Hence, the solution is 7/4

Step-by-step explanation:

We have four fractions and are asked to find the next one in the sequence.

So we see that 8/25 and 10/25 are together, which then follows up with 12/25 and 14/25.

Do we see a pattern? Yes indeed, the numerator is going up two values of every sequence, therefore we need to add 2/25 to 14/25 to find the next fraction.

[tex]\frac{14}{25} + \frac{2}{25}[/tex]

Mrs. Carter is preparing materials for a craft project. She needs to cut 5 meters of ribbon into pieces that are 0.5 meter long. How many0.5-meter pieces can she cut from 5 meters of ribbon?

Answers

5 divided by .5 equals 10
So she can cut 10 0.5 meters pieces from 5 meter of ribbon

Mrs. Carter can cut 10 pieces of ribbon that are 0.5 meters long from the 5-meter ribbon.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

For example 4/2 = 2

To amount of 0.5-meter pieces Mrs. Carter can cut from 5 meters of ribbon, we need to divide the total length of the ribbon (5 meters) by the length of each piece (0.5 meters):

⇒ 5 meters / 0.5 meters per piece = 10 pieces

The quotient (10) tells us that the unit rate of 0.5 meters fits into the total length of 5 meters 10 times.

Thus, he cut 10 pieces of ribbon that are 0.5 meters long from the 5-meter ribbon.

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

What is the best estimation of the equation 7/8 − 6/11? Drag the numbers into the boxes. Numbers may be used once, twice, or not at all.

Answers

Answer:

1 - 1/2 = 1/2

Step-by-step explanation:

These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.

The best estimation of the equation ⅞ - 6/11 is; ½

Fractions

To solve this question we need to know that sometimes when we want to get the rough estimate of some mathematical operations, it may be wise to approximate the number involved.

Now, ⅞ is closer to 1 than it is to ½ and so we will say; ⅞ ≈ 1

Similarly, 6/11 is closer to ½ than it is to 1 and so we say; 6/11 ≈ ½

Thus;

The operation ⅞ - 6/11 can be expressed as;

1 - ½ = ½

Vince says that based on the solution, he should save a maximum of $103.55.
Is Vince correct?
Vince is correct because he found the correct solution to the inequality.
Vince is correct because he should save at least $103.55.
Vince is not correct because he wrote the wrong inequality to represent the situation.
Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55.

No, he is not correct.

Step-by-step explanation:

$103.55 is the minimum, not maximum, amount that he should save. If he adds the $103.55 to his current total, he can only by the least expensive model. However, he may want to buy more than that model.
