Find the sum.

−57+90

Answer:

Let the number be x.

[tex]3*x+4=12*x-14[/tex]

[tex]3x+4=12x-14[/tex]

Subtract 4 from both sides:

[tex]3x+4-4=12x-14-4[/tex]

[tex]3x=12x-18[/tex]

Subtract 12x from both sides:

[tex]3x-12x=12x-18-12x[/tex]

[tex]-9x=-18[/tex]

Divide both sides by -9:

[tex]\frac{-9x}{-9} =\frac{-18}{-9}[/tex]

[tex]x=2[/tex]

The number is 2.

The Number is 2

A Number is an arithmetic value used for representing the quantity and used in making calculations.

Given that the product of a number and 3 is equal to the 14 less than product of twelve and that number.

Let the number be x

3x + 4 = 12x - 14

12x - 3x = 14 + 4

9x = 18

x = 2

Hence, the required number is 2.

Answer:

B is the correct answer

Step-by-step explanation:

Answer:

x=52 and y=39

Step-by-step explanation:

52 + 39 = 91

52 - 13 = 39

What you would do is make the equation:

91=X+(X-13)

Then, you would solve for X and once you find X, you would subtract 13 from it.

The answers should be 52 and 39.

Answer:

Twice the sum of 11.5 and 11 is 34.

Step-by-step explanation:

Twice the sum of a number and 11 is 34.

This implies the equation:

2x+11=34 -> Solve for X.

34-11=23.

23/2=11.5

X=11.5

Could also use Desmos calculator for this, in which it would look like:

(Brainliest?) ^^

Twice the sum of a number and 11 is 34 is 2(n + 11) = 34 and the value of n

is  6.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Twice the sum of a number and 11 is 34.

Assuming the number to be 'n', so the statement can be numerically expressed as,

2(n + 11) = 34.

2n + 22 = 34.

2n = 12. n = 6.

Answer:

$17.55

Step-by-step explanation:

simply multiply the price by the amount of the product so: 2.6*6.75= 17.55

Discount=35%

Sale price

The sale price of the bat will be;

⇒ $225.71

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

                                          = $121.54

Thus, The sale price = $347.25 - $121.54

                                = $225.71

Answer:

The positive integers between -7/3 and 5/2 are 1 and 2.

Step-by-step explanation:

"How many positive integers are between - 7/3 and 5/2?" can be written as "How many positive integers are between - 2 1/3 and 2 1/2?"  This rewriting makes it easier to identify the positive integers in question.  They are 1 and 2.

The number of positive integers between -7/3 and 5/2 is 3 (option H).

To determine the number of positive integers between -7/3 and 5/2, we need to find the positive integers greater than -7/3 and less than 5/2.

Converting -7/3 to a decimal, we have:

-7/3 ≈ -2.333

Converting 5/2 to a decimal, we have:

5/2 = 2.5

Now, let's check which positive integers lie between -2.333 and 2.5.

The positive integers greater than -2.333 and less than 2.5 are 0, 1, and 2.

Therefore, there are three positive integers between -7/3 and 5/2. The correct answer is option H. 3.

Step-by-step explanation:

The value after one year will be $535.

Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.

Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan. For example, a bank will pay you interest when you deposit your money in a high-yield savings account.

given:

amount= $500

interest rate = 7% on 3-year certificates of deposit.

So, after one year  the value will be

=500 x 7% + 500

=500 x 0.07 + 500

= 35 + 500

= $535

Hence, the value will be $535.
