Janice is building a fence around a portion of her rectangular yard. The length of yard she will enclose is x and the width is 2x2 − 99x + 3 where the measurements are in feet.

If the length of the enclosed yard is 50 feet and the cost of fencing is $14 per foot, how much will Janice need to spend on fencing?

Janice will need to spend $_____ on fencing.

Answer:

The answer is x=−2y+4

Step-by-step explanation:

1) Add -4y to both sides.

2x+4y+−4y=8+−4y

2x=−4y+8

Step 2: Divide both sides by 2.

2x/2=−4y+8/2

x=−2y+4

Hope this helps

Answer:

The sum is $10

Step-by-step explanation:

Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.

Answer:

19 because i used a calculatorrrrrrr

Answer:

Number of men= 13.99 = 14

Step-by-step explanation:

Giving the following information:

There are 49 female performers in a dance recital. The ratio of men to women is 2:7.

First, we determine the proportion of men to women:

Proportion men to women= 2/7= 0.2857

Now, we calculate the number of men in the show:

Number of men= 0.2857*49

Number of men= 13.99 = 14

Answer:

B 4.8 inches

Step-by-step explanation:

The scale factors are used to convert a figure into another one with similar characteristics but different lengths, in this example is a triangle, and in order to calculate the measure of the height you just have to multiply the original height by the scale factor:

Given:

The equation is

[tex]2(x+14)=40[/tex]

To find:

The solution of the given equation.

Solution:

We have,

[tex]2(x+14)=40[/tex]

Using distributive property, we get

[tex]2(x)+2(14)=40[/tex]

[tex]2x+28=40[/tex]

Subtracting 28 from both sides.

[tex]2x=40-28[/tex]

[tex]2x=12[/tex]

On dividing both sides by 2, we get

[tex]x=6[/tex]

Therefore, the solution of the given equation is x = 6.

Answer:

45

Step-by-step explanation:

27 DIVIDED BY 3 IS 9

SO 9 MULTIPLIED BY 5 IS 45

SO THE ANSWER IS 45

Answer:

k=8

Step-by-step explanation:

For 2 lines to be parallel, they must have the same slope. First, let's isolate y.

5y=2x+2

y=2/5x+2/5

Now, in our second equation, we must make it so that the slope is 2/5.

5(4)=20

2(4)=k

k=8

y=8/20x+10

If you simplify that, then the slope will be 2/5.

Answer:

590 centimeters

Step-by-step explanation:

Answer:

Answer:

the first third and fourth one

Step-by-step explanation:

16 / 3/4= 16(keep) x (change from dividing to multiplying) 4/3 (flip)

15 / 3/5= 15 (keep) x (change from dividing to multiplying) 5/3 (flip)

12 / 4= 12 (keep) x (change from dividing to multiplying) 1/4 (flip)

so you keep the first number change the sign like for example if its dividing you'll change it to multiplying and if its adding you'll change it to subtracting then flip the fraction

can i pleaseeee get brainliest thanks :))

This is a 2-step equation. We will solve it in 2 steps.

[tex]-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}[/tex]

The solution for this equation is x = [tex]\frac{7}{2}[/tex].

Step-by-step explanation:

The attached figure shows two triangles AOB and MON.

In triangles AOB and MON,

AB = MN (Given )

∠AOB = ∠MON (vertically opposite angles)

∠O = ∠O (common)

∴ ΔAOB ≅ Δ MON (ASA)

Angle-side-angle is the postulate that can be used to prove that two triangles are congruent.

Answer:

Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

Step-by-step explanation:

Total piece of wood bought = 7/8 foot

Piece of wood used for each small box = 3/16 foot

Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

= 7/8 foot ÷ 3/16 foot

= 7/8 × 16/3

= 7×16 / 8×3

= 112 / 24

= 4 16/24

= 4 2/3 small boxes

The equation is:

Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

Answer:

Carl's hourly pay rate is $16

Step-by-step explanation:

Let x is the hourly rate of Carl and y is the hourly rate of Derrick

∵ Carl's hourly rate is $x

∵ Derrick's hourly rate is $y

∵ Carl worked for 15 hours and Derrick worked for 20 hours

∴ Their combined pay was 15x + 20y

∵ Their combined pay was $640

→ Equate the value of the combined pay

∴ 15x + 20y = 640 ⇒ (1)

∵ The next week, Carl worked 20 hours and Derrick worked 25 hours

∴ Their combined pay was 20x + 25 y

∵ Their combined pay was $820

→ Equate the value of the combined pay

∴ 20x + 25y = 820 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by 5 and equation (2) by -4

∵ 5(15x) + 5(20y) = 5(640)

∴ 75x + 100y = 3200 ⇒ (3)

∵ -4(20x) + -4(25y) = -4(820)

∴ -80x - 100y = -3280 ⇒ (4)

→ Add equations (3) and (4)

∵ (75x + -80x) + (100y + -100y) = (3200 + -3280)

∴ -5x + 0 = -80

∴ -5x = -80

→ Divide both sides by -5 to find x

∴ x = 16

∴ Carl's hourly pay rate is $16

Answer:$16 I looked it up

Step-by-step explanation:

Answer:

(6x + 2) feet

Step-by-step explanation:

The formula for the perimeter of a rectangle = 2L + 2 W

Where L = Length

W = Width

Hence, the:

The length of the pool was (2x -3) feet and the width of the pool was (x + 4) feet.

The perimeter of the rectangular pool =

2(2x - 3) + 2(x + 4)

= 4x - 6 + 2x + 8

= 4x + 2x - 6 + 8

= (6x + 2) feet

Therefore, an expression for the perimeter of the pool area to be fenced is (6x + 2) feet

Step-by-step explanation:

A.P.E.X.

Given:

Consider the expression is [tex]\sqrt{-12}[/tex].

To find:

The value of given expression.

Solution:

We have,

[tex]\sqrt{-12}[/tex]

It can be written as

[tex]\sqrt{-12}=\sqrt{-1\times 12}[/tex]

[tex]\sqrt{-12}=\sqrt{-1}\times \sqrt{12}[/tex]      [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]

[tex]\sqrt{-12}=i\times \sqrt{12}[/tex]      [tex][\because \sqrt{-1}=i][/tex]

[tex]\sqrt{-12}=\sqrt{12}i[/tex]

Therefore, the value of given expression is [tex]\sqrt{12}i[/tex].

Note: all options are incorrect.
