Answer:

28

Step-by-step explanation:

Answer:

D ≈ 28 or D = [tex]\frac{88}{\pi }[/tex]

Step-by-step explanation:

D = C / [tex]\pi[/tex]

D = 88 / [tex]\pi[/tex]

OR

D = 88 / 3.14

D ≈ 28

He needs 1 and 1/3 cups of pinapple juice when he uses 3 cups of orange juice.

Step-by-step explanation:

Orange Juice:

3 cups / 3/4 cups = 12/3 = 4

Pineapple Juice:

1/3 × 4 = 4/3 cups= 1  1/3 cups

Answer:

5x+y=28

..................................

Answer:

Step-by-step explanation:

y = -5x + 8

y - 3 = -5(x - 5)

y - 3 = -5x + 25

y = -5x  + 28

Answer:

y= -12/5

Decimal form: -2.4

Step-by-step explanation:

Distribute the negative 3 on the left side

-3y-9=2y+3

Add 3y to both sides

-9=5y+3

Subtract 3 from both sides

-12=5y

Divide by 5 on both sides

y=-12/5 or -2.4

The variable x is a placeholder for a number

Let's say we replace x with 0

y = 2x+3

y = 2(0)+3

y = 0+3

y = 3

This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.

--------------

Let's repeat for x = 1

y = 2x+3

y = 2(1)+3 ... replace x with 1

y = 2+3

y = 5

So (1,5) is another point on the line

---------------

We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.

Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.

Answer:

10 minutes

Step-by-step explanation:

50 divided by 5= 10

Answer:

10 minutes

Step-by-step explanation:

You are dividing in this equation 50 by 5

50 divided by 5 is 10 since 10x5 is 50

Answer:

i  need free points, thank you

Step-by-step explanation:

Step-by-step explanation:

y varies x

y=kx

when y=5;x=6

5=6k

5/6=k

Now, when y=?;x=5

y=5\6(5)

y=25\6

y=4.17

T–4, 6(x, y) could be used to describe a horizontal translation to the right by 4 units, and a vertical translation up by 6 units

The rule is given as:

T–4, 6(x, y)

This can be rewritten as:

(x - 4, y + 6)

The above means that:

A horizontal translation to the right by 4 units, and a vertical translation up by 6 units

Answer:

632.6

Step-by-step explanation:

Z = .3 right? It looks weird on my screen

Anyway, if z is .3 than this is how to solve

First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)

622 + 2(0.3) + 10.

622 + 0.6 + 10.

622 + 10 + 0.6

632 + 0.6

632.6

Step-by-step explanation:

Answer:

y = -1/7x -6/7

Step-by-step explanation:

y = mx +b

m = -1/7

y = -1/7x +b

-4 = -1/7(-2)

-4 = -2/7

-4 + -2/7 = b

b = -6/7

y = -1/7x -6/7

Answer:2 pieces or 1 1/3

Step-by-step explanation:

cause if 2/3 was 1 piece and you divide by 1/2 you have double what you had making you have 2 pieces

Answer:

x^2 - 6x + 25

Step-by-step explanation:

( x + 1 ) ^2 -8( x - 1 ) + 16

undo the square

x^2 + 2x + 1 -8(x - 1) + 16

distribute

x^2 + 2x + 1 -8x + 8 + 16

simplify

x^2 - 6x + 25

Answer:

[tex] length = 12 ft [/tex]

[tex] width = 8 ft [/tex]

Step-by-step explanation:

Earl's garden:

[tex] length = (x + 6) ft [/tex]

[tex] width = (x + 2) ft [/tex]

[tex] perimeter = 2(length) + 2(width) [/tex]

[tex] perimeter = 2(x + 6) + 2(x + 2) [/tex]

[tex] perimeter = 2x + 12 + 2x + 4 = (4x + 16) ft [/tex]

Dylan's garden:

[tex] length = (2x - 2) ft [/tex]

[tex] width = (x + 4) ft [/tex]

[tex] perimeter = 2(length) + 2(width) [/tex]

[tex] perimeter = 2(2x - 2) + 2(x + 4) [/tex]

[tex] perimeter = 4x - 4 + 2x + 8 = (6x + 4) ft [/tex]

Generate an equation to solve for the value of x.

Since the perimeters of both gardens are the same, therefore:

[tex] 6x + 4 = 4x + 16 [/tex]

Collect like terms

[tex] 6x - 4x = - 4 + 16 [/tex]

[tex] 2x = 12 [/tex]

Divide both sides by 2

[tex] x = 6 [/tex]

Earl's garden:

[tex] length = (x + 6) ft [/tex]

Plug in the value of x

[tex] length = 6 + 6 = 12 ft [/tex]

[tex] width = (x + 2) ft = 6 + 2 = 8 ft [/tex]

Step-by-step explanation:

Was gonna brute force every question with a calculator but luckily A was correct. Substituted 25 for x and found all the angles. 5x was 125, which I subtracted from 180 to find the interior angle, 55°. 3x was 75.
