Answer:

If the two numbers are x and y, then:

x + y = 8

18 - 2x = 4y - 2.

When we subtract y from both sides in our first equation we get:

x = 8 - y, so:

18 - 2(8 - y) = 4y - 2

18 - 16 + 2y = 4y - 2

2 + 2y = 4y - 2

2y = 4

y = 2

Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.

Step-by-step explanation:

Let x be the length and y be the width of the rectangular plot.

The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,

x+2y = 1500

x = 1500 - 2y ....(1)

We know that the area of a rectangular plot is given by :

A = xy ....(2)

Put the value of x from equation (1) in (2)

[tex]A=(1500-2y)y\\\\A=1500y-2y^2[/tex] .....(3)

For largest area, differentiate above area equation wrt y.

[tex]\dfrac{dA}{dy}=\dfrac{d}{dy}(1500y-2y^2)\\\\=1500-4y\\\\\text{Put}\ \dfrac{dA}{dy}=0\\\\1500-4y=0\\\\y=\dfrac{1500}{4}\\\\=375[/tex]

Put the value of y in equation (1).

x = 1500-2(375)

= 750 m

Put the value of y in equation (3).

[tex]A =1500(375)-2(375)^2\\A=281250\ m^2[/tex]

Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.

Answer:

D $26

Step-by-step explanation:

1/3(9x+45)-x=6x+4

we can move the numbers on the right and the x's on the left

9x/3+45/3-x=6x+4

3x-x-6x=4-15

-4x=-11

x=11/4

Answer:

x=4

Step-by-step explanation:

I did the edge quiz pretty sure I got it correct

Answer:

x=4

Step-by-step explanation:

Brand A: 32 Diapers, $8.99: about 28 cents per diaper

Brand B: 50 Diapers, $12.49: about 24 cents per diaper

You divide the amount of diapers by the money.

For example, 32 diapers/$8.99 equals about 28 cents per diaper and 50 diapers/$12.49 equals about 24 cents per diaper.

Brand B is the better deal since you save about 4 cents more.

Answer:

(-9x^2-2x)-(-9x^2-3x)

Step-by-step explanation:

Answer:

The slope would be 2

Step-by-step explanation:

All you do is pick two order pairs: (2,6) and (4,10),  then you do y1 - y2, so 10-6 to get 4 then do x1 - x2, so 4 - 2 which is 2, then you divide 4 by 2 to get 2.

Answer:

the answer is 222

Answer:

222

Step-by-step explanation:

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

37/100 = X/600

X/600 = 37/100

X*600/600 = 37*600/100

X = 22200/100

X = 222

Answer:

30

Step-by-step explanation:

(86-32)/1.8 =30

Given:

In ΔHIJ, h = 40 cm, ∠J=20° and ∠H=93°.

To find:

The length of j, to the nearest centimeter.

Solution:

According to Law of sine,

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

In ΔHIJ, using law of sine, we get

[tex]\dfrac{j}{\sin J}=\dfrac{h}{\sin H}[/tex]

[tex]\dfrac{j}{\sin (20^\circ)}=\dfrac{40}{\sin (93^\circ)}}[/tex]

[tex]j=\dfrac{40\times \sin (20^\circ)}{\sin (93^\circ)}}[/tex]

On further simplification, we get

[tex]j=\dfrac{40\times 0.34202}{0.99863}[/tex]

[tex]j=\dfrac{13.6808}{0.99863}[/tex]

[tex]j=13.69958[/tex]

Approximate the value to the nearest centimeter.

[tex]j\approx 14[/tex]

Therefore, the length of j is 14 cm.
