Actually, it's C multiplication Cutty you can't be giving Wrong answers.

Step-by-step explanation:

It's C Multiplication because Were using the PEMDAS technique and this stands for

P- Parenthesis

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction

So if you see in the Pemdas technique It will be C Multiplication.

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

The easiest way to tell if a relation is a function is to look at the values of the x's. If more than one x is the same, it cannot be a function. In contrast, if more than one y is the same, it is okay. The answers A, B, and D are functions because the x's are all different. Looking at the table for the answer C, you can see that two x's are the same (there are two x's with the value of 1).

Step-by-step explanation:

Answer:

The value of x is 3

Step-by-step explanation:

The stage is rectangular in shape.

The formula for area of a rectangle is:

Length × Width

Length = 24 feet

Width = 4x + 4 feet

Hence:

384 = (4x + 4) × (24)

384 = 96x + 96

Collect like terms

384 - 96 = 96x

288 = 96x

x = 288/96

x = 3

The value of x is 3

Answer:

Subtract 10 from both sides of the equation. The equation in standard form is:

y = [tex]7m^{2}[/tex] + 3m + 1

Step-by-step explanation:

To convert [tex]7m^{2}[/tex] + 3m + 11 = 10 into standard form ( y = ax^2 + bx + c), subtract 10 from both sides of the equation to make the equation equal to zero:

[tex]7m^{2}[/tex] + 3m + 11 = 10

[tex]7m^{2}[/tex] + 3m + 11 - 10 = 10 - 10

[tex]7m^{2}[/tex] + 3m + 1 = 0

Replace the 0 with y and you have your answer :)

Step-by-step explanation:

because if you find oh nvm you know what a common factor is

Answer:

C, 20

Step-by-step explanation:

The answer is 20 because the multiple of a number can not be less than the number itself so we can cross out the option 2 and 4 because they are both less than 10. We can then check if 20 and 40 fit the requirements of being a multiple of both 10 and 4. They both fit but it asks for the LEAST common multiple and because 20 is smaller than 40, we can find our answer to be C, 20.

Answer:

$2.69

Step-by-step explanation:

here is with distribution...

1. add all the original prices together

2.50+4.95+6.00=13.45

2. multiply that sum(13.45) by 0.2(0.2 IS THE 20% OFF)

13.45x0.2=2.69

FINAL ANSWER: $2.69

Answer:

Answer:

x = 13

y = 12

Step-by-step explanation:

4x and 52 have to be equal because they are opposites on the same line. So because of this we can make a simple equation to find x.

4x = 52

divide both sides by 4 and you have x

x = 13

to find y on the other equation, since we know two of the angles, we can add up all three angles and make them equal to 180 (the sum of all angles on a triangle)

90 + 52 + (3y +2) = 180

first subtract 90 and 52 from both sides to leave the equation alone

3y + 2 = 38

second substract 2 to isolate the variable

3y = 36

lastly divide both sides by three

y = 12

Given:

The system of equations is

[tex]x+3y=42[/tex]       ...(i)

[tex]2x-y=14[/tex]        ...(ii)

To find:

The number that must be multiplied with the second equation to eliminate the y-variable.

Solution:

Coefficient of y variable in equation (i) is 3 and in equation (ii) is -1.

To eliminate y-variable the absolute value of coefficients of y-variables should be same.

So, we need to multiply the second equation by 3 to eliminate the y-variable

Multiplying equation (ii) by 3, we get

[tex]6x-3y=42[/tex]      ...(iii)

Adding (i) and (iii), we get

[tex]x+3y+6x-3y=42+42[/tex]

[tex]7x=84[/tex]

Divide both sides by 7.

[tex]x=12[/tex]

Put x=12 in (i).

[tex]12+3y=42[/tex]

[tex]3y=42-12[/tex]

[tex]3y=30[/tex]

Divide both sides by 10.

[tex]y=10[/tex]

Therefore, x=12 and y=10.

Answer:

Multiply the second equation by 3. The solution is x = 12, y = 10.

Answer:

angle 1 =135

Step-by-step explanation:

it is 180 degrees total. We know that there are two angles that have a ratio to 3:1. So, assign x to 2. Since 1 = 3x, we do 3x+x =180

4x=180

x=45 or angle 2

180-45=135 or angle 1

Multiply angle 2 by 3 to check if its correct

Answer:

the measurement of angle 1 is 135 degrees. (i think)

Step-by-step explanation:

so we know that angle 1 and 2 are at a 3:1 ratio

and that 1 and 2 add to 180 degrees

if you plug the number 45 in to angle 1, then multiply that by 3 you get 135

the remaining number to add to 180 would be angle 2

which is 45 degrees.

If the explanation is choppy or hard to read, apologies, its fairly hard for me to explain this.

however i hope this helps.

I think in order to solve this, you would need to add up the fractions that they used. So it would be,

[tex]\frac{1+1}{4} +\frac{3+3+5+5+5+7}{8}[/tex]    Calculate the sum

[tex]\frac{2}{4} +\frac{28}{8}[/tex]    Reduce

[tex]\frac{1}{2}+\frac{7}{2}[/tex]   Transform the Expression

Answer:

Step-by-step explanation:

The number of pennies will be 2 more than a multiple of 10. 2 pennies and 9 dimes is not enough coins. 12 pennies and 8 dimes is exactly enough.

__

This one is easy to figure by "trial and error," as there is only one trial that makes any sense.

If you want to figure it using an equation, it usually works well to let a variable represent the quantity of the higher-value coin. If d is the number of dimes, then 20-d is the number of pennies. The total number of cents is ...

  10d +(20-d) = 92

  9d = 72 . . . . . . . . . subtract 20

  d = 8

  20-d = 12

There are 8 dimes and 12 pennies.

Answer:

The net tax refund of Harry and Helen is $555.

Step-by-step explanation:

The net tax refund of Harry and Helen is $555.

The marginal tax rate is the tax rate imposed on the additional dollar. In general, as a taxpayer's income rises, so does his or her marginal tax rate. It is also known as progressive taxation since the taxpayer with the highest income pays the highest level of income tax.

As, To calculate their due tax liability, the total withheld amount for the year will be subtracted from the overall tax liability.

So, Due Tax Liability

= Total tax Liability - Total withheld Amount

= 9169 - (187 x 52)

= $55.
