What is the coefficient in the expression; 21 + 3x

Answer:

(2,[tex]\frac{5}{2}[/tex])

Step-by-step explanation:

Midpoint formula: M=([tex]\frac{x_{1} +x_{2} }{2}[/tex],[tex]\frac{y_{1} +y_{2} }{2}[/tex])

M=([tex]\frac{2+2}{2}[/tex],[tex]\frac{1+4}{2}[/tex])

=([tex]\frac{4}{2}[/tex],[tex]\frac{5}{2}[/tex])

=(2,[tex]\frac{5}{2}[/tex])

Insert parentheses to make the number sentence true will be [1 + (2 × 3)] × 4 = 28.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The equation is given below.

1 + 2 × 3 × 4 = 28

Insert parentheses to make the number sentence true will be

[1 + (2 × 3)] × 4 = 28

[1 + 6] × 4 = 28

7 × 4 = 28

28 = 28

Insert parentheses to make the number sentence true will be [1 + (2 × 3)] × 4 = 28.

Answer:  y = 23        x = 28

Step-by-step explanation:

First find the value of y.

The angle (5y -4)  and 3y forms a straight line which means that if you add them together they will equal 180 degrees.  Add them and set them equation to 180 to solve for y.

5y-4 + 3y = 180  

8y -4 = 180

    +4    +4

  8y = 184

 y= 23  

Since y is equal to 23, then input y into the expression  (5y-4) to find the main angle value and then add it with the angle (2x+13) to equal to 180 degrees because they also form a straight angle.

5(23) - 4

115 - 4 = 111

111 + (2x + 13) = 180  

124 + 2x = 180  

-124           -124

 2x = 56

x = 28  

x is equal to 28 degrees.  

Check.

111 + 2(28) + 13 = 180

 111 + 56 + 13 = 180

     180 = 180

Answer:

2 electrons

Step-by-step explanation:

An atom is neutral if it has no charge. That means the positive and negative charge balance each other out.

There are two protons, so that is a charge of +2. To make the charge 0, there needs to be a charge of -2. -2= 2 electrons.

Hope I can help.

Kiaya can make a $25 withdrawal for 11 weeks without incurring a fee.

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

Kiaya needs to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now, so she can make $376 - $100 = $276 worth of withdrawals before she will be charged a fee.

Each week, she makes a $25 withdrawal.

To determine the number of weeks she can make this withdrawal before being charged a fee, we divide the total amount she can withdraw ($276) by the amount she withdraws each week ($25).

So, Kiaya can make $276 / $25 = 11 withdrawals before she will be charged a fee.

Therefore, she can make a $25 withdrawal for 11 weeks without incurring a fee.

Answer:

19x+8

Step-by-step explanation:

First distribute 2 into the parenthesis which will equal 12x+8+7x

Than add like terms 12x+7x =  19x

Than youre left with 19x+8 and that is the answer :}

Answer:

19x+8

Step-by-step explanation:

You multiply everything in the parenthesis by 2 and then get rid of the parenthesis so then the equation will be 12x+8+7x. Then you add 12x and 7x together because you can't add together a normal number and a variable. Then the equation will be 19x+8. This is the final equation.

Answer:

Step-by-step explanation:

this week sold = $2,760

last week sold = $2,400

the difference from this week to last week = 2700-2400 = 360

that means it increased : 360 / 2400 = 0.15 (100%) = 15%

therefore, the increase of sale is 15%

Step-by-step explanation:

"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...

  24 23/100

_____

Additional comment

You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.

Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.
