8 - 2x = 6x - 10x + 18

Answers

Answer 1
Answer:

Answer:

X=5

Step-by-step explanation:

8 - 2x = -4x + 18

+4. +4

8+2x = 18

-8. -8

2x= 10

/. /

2. 2.

Sooo if we're looking for X I'd say X= 5

Having trouble with this one

Answers

Answer:

Yes

Step-by-step explanation:

If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.

The slope of AC is:

m = (3 − 3) / (6 − 0) = 0

The slope of BD is:

m = (0 − 6) / (3 − 3) = undefined

The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.

Specifically, AC is horizontal and BD is vertical.

Sue had $2.70 in dimes and nickels. If she has 12 more dimes than nickels, how many of each coin does she have?

Answers

she has 27 dimes and 15 nickles. there are 10 dimes in a dollar each worth 10 cents. two dollars and 70 cents so that would be 20 dimes in two dollars and 7 dimes is equal to 70 cents.

Mr Thompson wants to cut a 5-ft rope into a 1/4-ft sections how many 1/4 sections will he have

Answers

Answer:

20 pieces of rope

Step-by-step explanation:

Mr. Thompson has a 5-ft rope. If he cuts the rope into 1/4-ft pieces, that means for every foot, there are 4 pieces of rope. There are 5-ft of rope, so we multiply 5 and 4 to get the number of pieces of rope.

5 x 4 = 20 pieces of rope.

I hope that this helps! :)

Kenny worked 6.5 hours on Monday, and 5 hours on Tuesday. If he received a check for $143.75 for working those 2 days, how much does Kenny make per hour?

Answers

Answer:

Kevin makes $12.50 per hour.

Step-by-step explanation:

If Kevin works 6.5 hours on Monday and 5 hours on Tuesday, he works a total of 11.5 hours. Over 11.5 hours he makes $143.75. To find your answer, you have to divide your total earned, 143.765, by the total time worked, 11.5 hours. Your answer should then be 12.5, which is the amount per hour kevin earns.

6.Write the equation in slope-intercept form for the line that passes through the given pointand is perpendicular to the given equation.5x + 3y = -21 and passes through (-5, 1)

Answers

Let us first solve for the slope (m) of the perpendicular line.

\text{ 5x + 3y = -21}\text{ 3y = -5x - 21}\text{ y =}\frac{-5x\text{ -21}}{3}\text{ y = -}(5)/(3)x-7

The slope of the perpendicular line is -5/3.

Thus, for the slope of the line, we get,

\text{ m}_(\perp)\text{ = }(-5)/(3)\text{ m = }(3)/(5)

Let us solve for the value of b with the given value of slope (m) = 3/5 and (x,y) = (-5,1).

\text{ y = mx + b}1\text{ = (}(3)/(5))(-5)+b1\text{ = -1 + b ; b = 1 + 1 = }2

Let's now make the equation of the line using Slope-Intercept Form,

Given, m = 3/5 and b = 2

\text{ y = mx+b}\text{ y = (}(3)/(5))x\text{ + 2}

\text{ y = }(3)/(5)x\text{ +2}
