The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions? ​

Answers

Answer 1

Answer:

Width =15

Length =33

Step-by-step explanation:

Take width as x

And length as 2x+3

Perimeter as 96

Formula of the perimeter of a rectangle is 2l+2w

X+×+2×+3+2×+3=96

6x+6=96

6x=96-6

6×=90

X=15

Width =x and x =15 so width =15 while length =33

m∠AFC = 65º + 45º

m∠AFC = 110º

m∠BFD = m∠BFC + m∠CFD

m∠BFD = 45º + 70º

2(x+4)= -5x+1
Some one please solve

Answers

Let's solve your equation step-by-step.

2(x+4)=−5x+1

Step 1: Simplify both sides of the equation.

2(x+4)=−5x+1

(2)(x)+(2)(4)=−5x+1(Distribute)

2x+8=−5x+1

Step 2: Add 5x to both sides.

2x+8+5x=−5x+1+5x

7x+8=1

Step 3: Subtract 8 from both sides.

7x+8−8=1−8

7x=−7

Step 4: Divide both sides by 7.

Answers

Answer:

C

Step-by-step explanation:

It needs to be an "or" inequality because it is one or the other, not both. The reason C is correct is because the number needs to be between 4 and 6 or 8 and 10, so greater than the former but still less than the latter.

How do you evaluate 3x+8 when x=2?

Answers

Plug the x in :)

3(2) + 8
6 + 8
=14

Answer:

3x + 8 is equal to 14 when x = 2.

Step-by-step explanation:

To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression.  We can write this expression as the function:

f(x) = 3x + 8

And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:

f(x) = 3x + 8

f(2) = 3(2) + 8

f(2) = 6 + 8

f(2) = 14

Hence, the expression 3x + 8 is equal to 14 when x = 2.

what is the measure of W in the figure

Greetings from Brasil...

In angle A we have supplementary angles, that is

From the properties of the angles of a triangle - refer to attached,

W = X + 105

as X = 50 - already calculated above, then

use the properties of equality to show that the equation 6x + 3 = 27 is equivalent to the equation 2x = 8.

Answers

Answer:

Step-by-step explanation:

The equation 6x + 3 = 27 is equivalent to 2x = 8 because you can divide 8 by 2x to get X=4. To solve 6x + 3 = 27, you can subtract 3 to both sides of the equal sign to end up with 6x = 24, and from there you can divide 24 by 6x and also end up with X = 4. Both equations have the same answer.

Write an integer that represents a $3 loss.

Answers

Answer: -3 or -$3.

Step-by-step explanation:

First, the set of integer numbers is the set of all the whole numbers (negatives, zero, and positives).

We want to write a $3 loss, now, the most important part here is that we have a loss, so we must represent this with a negative number.

Then we can write this as:

"An integer that represents a $3 loss"

is -3 or -$3 (if we want to also respect the units)
