Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of
your work
Part A: 5 + 2 = 232 + 13
Part B:5 + 1 = 23% + 13

Answers

Answer 1

Answer:

Part A: 7 = 245

Part B: 6 = 1323/100

Step-by-step explanation:

Part A: Add the numbers 5 and 2 which you get 7 and then you add 232 and 13 which gives you 245

equation version: 5 + 2 = 7

232 + 13 = 245

7 = 245

Part B: In order to convert a precent to a ratio, divide it by 100

23/100

5 + 1 = 23/100 + 13

5 + 1 = 6

23/100 + 13 = 1323/100

6 = 1323/100

Hope this helps :)

which expression is undefined?

which expression is undefined?

Answers

D. 15/9+(-9) really just means 15/9-9
Hence, 15/0
You cannot divide by 0 so you get an undefined answer

Answer:

D

Step-by-step explanation:

If the denominator ( bottom number ) is 0 then the expression is undefined. This is simply because a number cannot be divided by 0. However 0 can be divided by a number, the quotient would just end up being 0 though. This means that the numerator ( top number ) can be 0 and the expression will be defined

A. 0 / 3 = 0

0 is a defined answer so A cannot be the answer

B. \(\frac{0-8}{-4} =\frac{-8}{-4} =2\)

2 is a defined number so B cannot be the answer.

C \(\frac{7-7}{9} =\frac{0}{9} =0\)

0 is a defined number so C cannot be the answer

D \(\frac{15}{9+(-9)} =\frac{15}{0} =\) undefined

Because 15 is being divided by 0 and no number can truly be divided by 0 the quotient is undefined therefore D is the answer

Mrs. Canter's math class went outside and plucked blades of grass and then measured them. The line plot

Answers

Answer: 1 1/4

Step-by-step explanation: The shortest blade of grass is 2/4 of an inch. The tallest blade of grass is 7/4 inches.  You must subtract 7/4 by 2/4 to get the answer. Subtract the numerator of the tallest blade of grass by the smallest blade of grass. 7/4-2/4=5/4. When you convert that to a mixed number you get 1 1/4.

Answer:

Step-by-step explanation:

Based on the information in the histogram, a reasonable conclusion would be that the exact time it took the students to finish the test is not indicated. Therefore, option B is the correct answer.Mrs. Brim made a chart to see how long it took her students to finish a test. However, the chart or histogram only shows how many students took a certain amount of time to finish the test and not their exact finishing time. Therefore, it's not possible to determine how long each student took to finish the test accurately.

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answer:

-5x+12=-12x-12 and -5+12=5x+12

Step-by-step explanation:

I believe it is that hopefully you don't need work I'm to lazy.

Answer: A and D

Step-by-step explanation:

**REFERENCE**

Variable term: An x term, or a number with an x beside it, like 5x, 3x, 9x, etc.

Constant: A number with no letter beside it, like 5, 3, 10, and 1.

***

________

There are 2 ways to answer this. One is to solve all the equations, but another is to remember 3 simple rules.

1. For an equation to have one solution, they must have different variable terms and different constant terms.

- Example: 2x+12= 3x+15. The variable terms, 2x and 3x are ddifferent, and 12 and 15, the constants, are different as well.

2. For an equation to have no solutions, they must have the same variables on both sides, but different constants.

- Example: 2x+12=2x+9. The variables, 2x, are the same, but the constants, 12 and 9, are obviously different.

3. For an equation to have infinite solutions, both the variable and the constant terms must be the same on both sides.

-  An example of an equation with infinite solutions is 2x+12=2x+12. The variable terms, 2x, are the same, and the constant term, 12, is also the same on both sides,

That being said, let's look at the 4 answer choices and determine how many solutions they have.

A. -5x+12=-12x-12

Rearranged for context: 12-5x= -12-12x

Variable terms: -5x and -12x. The variable terms are different.

Constant terms: 12 and -12. The constant terms are different

In option A, the variable and the constant terms are different. therefore it has 1 solution. A is correct.

B. -5x+12=5x+12

Rearranged for context: 12-5x=12+5x

Variable terms: -5x and 5x. They are different

Constant terms: 12 and 12. They are the same.

In option B, the variable terms are different but the constant terms are the same. This one is very confusing but since they don't have BOTH different variables and constants, I'll just assume that it doesn't have 1 solution.

C. -5x+12=-5x-12

Variable terms: -5x and -5x. SAME VARIABLES

Constant terms: 12 and -12. DIFFERENT CONSTANTS

No solutions

D. -5x+12=5x-5

Variables: -5x and 5x

Constants: 12 and -5

BOTH DIFFERENT

1 SOLUTION

D is correct.

hope this helps!! :D

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?

Answers

5,
3 is 1/3 of 9, meaning the probability of picking up a quarter is 1/3, if he finds 15 more,
15/3 is 5.

5 coins should be quarters

Answer: 5 coins

Step-by-step explanation:

Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.

Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.

If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:

\(\large \frac{1}{3} \times 15 = 5\)

Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.​

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.
