5x -12/x-1

C is the answer hope this helps!

Please mark me as brainliest if you can, I really appreciate it!

Answer 2

Answer:

Answer:

$(5x-12)/(x-1)$

Step-by-step explanation:

$(8x-5)/(x-1)$ - $(3x+7)/(x-1)$

= $(8x-5-3x-7)/(x-1)$

= $(5x-12)/(x-1)$

Can both number be negative? if yes give an example

Answers

yes they can.
for example if you have - 7 + - 8=- 15 the rule for adding/subtracting is that when you have two negative you add and keep the negative sign. When you multiply/divide the two negative makes the answer become positive for example - 5 × - 7 = 35 or when you divide - 6 ÷ - 3 = 2.

Step-by-step explanation:

y = x+.6

Solve for x

Subtract .6 from each side

y-.6 = x+.6 -.6

y-.6 =x

Let y = 3 y-.6 = 3-.6 = 2.4 =x x=2.4

Let y=4.2 y-.6 = 4.2 - .6 = 3.6 =x x=3.6

Let y =2 y-.6 = 2-.6 =1.4 =x x=1.4

rosa wants to use $20 to buy games. The inequality 2.50k+5.50≤20.00 represent the number of games, k, she can buy with her money. What is the greatest number of games Rosa can buy?

Answers

Answer:

The greatest number of games Rosa can buy is 5

Step-by-step explanation:

Let

k ----> the number of games, k, that Rosa can buy with her money

we have

$2.50k+5.50\leq 20.00$

solve for k

subtract 5.50 both sides

$2.50k\leq 20.00-5.50$

$2.50k\leq 14.50$

divide by 2.50 both sides

$k\leq 5.8\ games$

therefore

The greatest number of games Rosa can buy is 5

If a radius of a circle is 12 feet, what is the area and perimeter of the circle?

Answers

Perimeter: 75.4 ft

Step-by-step explanation:

Formula for area: $\pi r^(2)$

Formula for perimeter: $\pi d$ or $2\pi r$

How do you think you could represent the number 2,300 as a number times a multiple of 10? How do you think you could represent the number 2,300 as a number times 10 to some exponent? How would you describe the relationship between the two representations? plzz helppp

Answers

The number 2.3 is the coefficient, the number 10 is the base while the number 3 is the exponent.

In the scientific notation, a number is written followed b an exponent. It is necessary to note that the scientific notation is used to reduce the size of digits to something manageable.

The number 2,300 can best be represented as a number times 10 to some exponent in the manner 2.3 × 10^3. The number 2.3 is the coefficient, the number 10 is the base while the number 3 is the exponent.

In common scientific notation, any nonzero quantity can be expressed in two parts: acoefficient whose absolute value is greater than or equal to 1 but less than 10, and a power of 10 by which the coefficient is multiplied. In some writings, the coefficients are closer to zero by one order of magnitude. In this scheme, any nonzero quantity is expressed in two parts: a coefficient whose absolute value is greater than or equal to 0.1 but less than 1, and a power of 10 by which the coefficient is multiplied. The quantity zero is denoted as 0 unless precision is demanded, in which case the requisite number of significant digits are written out -- for example, 0.00000.
