How do I solve 2(6x +4) +7x by simplifying the expressions?

Answers

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.

The average smoker typically pays 15% higher life insurance costs than the average non-smoke. If the monthly cost to a non-smoker is $500 dollars per month, how much would the average smoker pay per month for the same life insurance policy?

Answers

Answer:

$600 for a smoker

Step-by-step explanation:

On average, smokers will typically pay 15-20% higher premiums than non-smokers with equivalent demographics and health conditions. If the monthly premium for a non-smoker is $500 per month, it will be upwards of $600 for a smoker. The health insurance companies face a double-edged sword when it comes to insuring smokers.

I need to find x and I can’t find it someone pls help me
Find X

Answers

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

last week sold = $2,400

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

therefore, the increase of sale is 15%

Kiaya has to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now. Each week, she makes a $25 withdrawal. For how many weeks can she make this withdrawal and avoid a fee?

Answers

Answer:

$500 a week

Step-by-step explanation:

Hope I can help.

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

What is the division operation?

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.

Step-by-step explanation:

9514 1404 393

Answer:

  24 23/100

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.
