Which pair of equations could not be used to solve the following equations for x and y?
4 + 2 = 22
−2 + 2 = −8

A.4 + 2 = 22 B. 12 + 6 = 66 C. 4 + 2 = 22 D. 8 + 4 = 44
2 − 2 = 8 6 − 6 = 24 -4x + 4y =-16 -8x + 8y = -8

Answers

Answer 1

Answer: 4

Step-by-step explanation:

I was looking for the answer for this question for my own homework, and the answer is four on mine, however this post wasn't clearly formatted so I can't tell the difference between answers...

For those of you who are here from a g00gle search:

THE ANSWER IS:

8x + 4y = 44

-8x + 8y = -8

BECAUSE ONLY ONE SIDE OF THE SECOND EQUATION WAS MULTIPLIED BY FOUR

Compare the ratios. Is Celeste using the correct ratio of apples to oranges?

Answers

No, she is incorrect. The first set of ratios is a 5:6 ratio, where as the second set is a 2:3 ratio.

The ratio for the first table is 5/6.

The ratio for the second table is 2/3.

Yes, Celeste is using the correct ratio of apples to oranges.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

From the first table,

The ratios of apples and oranges.

- 5/6

- 10/12 = 2x5/2x6 = 5/6

- 15/18 = 3x5/3x6 = 5/6

- 20/24 = 4x5/4x6 = 5/6

From the second table,

The ratios of apples and oranges.

- 2/3

- 4/6 = 2x2/2x3 = 2/3

- 6/9 = 3x2/3x3 = 2/3

- 8/12 = 2x4/3x4 = 2/3

Thus,

The ratio for the first table is 5/6.

The ratio for the second table is 2/3.

Answers

This is the actual answer:

The missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.

What is congruence in the triangles?

The measurements of the sides and angles of two or more triangles determine their congruence. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of corresponding sides and angles of two triangles are equal, they are said to be congruent.

We have:


As we can see in the diagram,

First, we will draw PU

PU is the common side for both the triangles

PU ≅ PU (reflexive property)

UO ≅ UR (given)

PO ≅ PR (given)

By the property of SIde-Side-Side

The triangle OUP  ≅ Triangle RUP

By Corresponding parts of congruent triangles are congruent:

Angle O ≅ Angle R (proved)

Thus, the missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.

2. The difference between 3 and 7 cans of red bull are $10. 4 cans are $10. Each can is 2.50.

Step-by-step explanation:

Answer:

a. The relationship is NOT proportional

b. The constant of proportionality is 0.4

Step-by-step explanation:

a. The numbers in the table are not proportional. We can tell that by dividing the top numbers by the bottom numbers they're matched with to find and compare ratios. 2/72=0.0277, but 8/296=0.0270, so since they're not equal, they're not proportional.

b. We find the constant of proportionality by doing the same thing as we did to find the ratios above. So 3/7.50= 0.4. To make sure the rate is the same, we'll also check that 7/17.50=0.4. Since it does, we know that that's the answer.
