The length of a rectangular sign is 5 times its width. If the sign’s perimeter is 24 inches, what is the sign’s area?

Answers

Answer:

A=20

Step-by-step explanation:

Let the width be x

x=width. 5x =L

2(L+W)=p

2(5x+x) =24

10x+2x=24

12x=24

12x/12 =24/22

x=2

A =LxW

A = (5x2)x x

A =10 x2

A=20

Answer:

Therefore, the values of "x" and "y" are -1000/312 and -115/39 respectively.

Step-by-step explanation:

★ Solution :-

[tex] \sf \leadsto 8x - 7y = -5 - - - (i)[/tex]

[tex] \sf \leadsto -x + 4y = -15 - - - (ii)[/tex]

By first equation,

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x = -5 + 7y[/tex]

[tex] \sf \leadsto x = \dfrac{-5 + 7y}{8} [/tex]

Now, we can find the original value of y.

[tex] \sf \leadsto -x + 4y = -15[/tex]

[tex] \sf \leadsto \bigg( \dfrac{-5 + 7y}{8} \bigg) + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y}{8} + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y + 32y}{8} = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 39y}{8} = -15[/tex]

[tex] \sf \leadsto -5 + 39y = -15(8)[/tex]

[tex] \sf \leadsto -5 + 39y = -120[/tex]

[tex] \sf \leadsto 39y = -120 + 5[/tex]

[tex] \sf \leadsto 39y = - 115[/tex]

[tex] \sf \leadsto y = \dfrac{ - 115}{39} [/tex]

Now, we can find the original value of x.

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x -7 \bigg( \dfrac{ - 115}{39} \bigg) = -5[/tex]

[tex] \sf \leadsto 8x + \dfrac{805}{39} = -5[/tex]

[tex] \sf \leadsto \dfrac{312x + 805}{39} = -5[/tex]

[tex] \sf \leadsto 312x + 805 = -5(39)[/tex]

[tex] \sf \leadsto 312x + 805 = -195[/tex]

[tex] \sf \leadsto 312x = -195 - 805[/tex]

[tex] \sf \leadsto 312x = -1000[/tex]

[tex] \sf \leadsto x = \dfrac{-1000}{312} [/tex]

Plot all points that are a distance of 7 units from 4. What are their values?

Answers

Distance is the number of units between points.

The distance that are 7 units from 4 are: 11 and -3

A distance of 7 units from 4 means:

[tex]x - 7 = 4[/tex] or [tex]x + 7 =4[/tex]

Where:

x is the required distance

Solve for x in both equations.

[tex]x - 7 = 4[/tex]

[tex]x = 7 + 4[/tex]

[tex]x = 11[/tex]

[tex]x + 7 =4[/tex]

[tex]x =4 - 7[/tex]

[tex]x =- 3[/tex]

So, the distance that are 7 units from 4 are: 11 and -3

The length of the side CD which is the base of the right triangle CDE is 15 feet which is option D.

We have,

We can use the Pythagorean theorem to solve for the length of the height CD in the right triangle CDE.

Where CE is the hypotenuse and De is the base.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we have:

CD² + DE² = CE²

Plugging in the given lengths:

CD² + 8² = 17²

CD² + 64 = 289

CD² = 289 - 64

CD² = 225

CD = √225

CD = √15²

CD = 15

Thus,

The length of the side CD which is the base of the right triangle CDE is D. 15 feet.

Ben gets $50 per day as wages and $6.00 as commission for every book he sells in a day. His daily earnings goal is $140.
Using the equation constructed in previous question, solve for the

Answers

$140 = $6 per book • x books + $50

Subtract $50 from $140 and you get:
$90 = $6 per book • x books

Divide $90 by $6 per book:
And you get x = 15 books

Answer:

the basic wage is 50$

the extra to get 140$ is 90$(140-50)

can someone explain how to solve the angle A

Answers

I cannot explain but from various examples that I have seen I would say that Angle A is either 30°, 40°, or 45°

An angle measures 64.8° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer: angle 1 = 56 and angle 2 = 124

Step-by-step explanation:

Supplementary angle equal 180 degrees

let X be angle 1 and X +68 be angle 2

x + x + 68 = 180

2x + 68 = 180

- 68 - 68

2x = 112

x = 56

x + 68 = 56 + 68 = 124

Step-by-step explanation:

A parallel line will have the same slope as the given line so we can write the slope-intercept form of the equation as

[tex]y = -3x + b[/tex]

Since the other line goes through the point (9, 0), we can use this to solve for b:
