Step-by-step explanation:

Answer:

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:

[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]

l: 12ft

Answer:

A:25

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.

75+55+50=180°

Answer:

2/3 is equal to .6 repeating

Step-by-step explanation:

also youre not dumb :)

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:

-1/4

Step-by-step explanation:

because its going up one over 4 and the lines negative!

Answer:

-1/4

Step-by-step explanation:

The slope is going down towards the right so it's negative. Rise-1 and you Run-4 so the answer is -1/4. Hope this helps :)

Answer:

3

Step-by-step explanation:

the answer

Answer:

a. 1/5

b. (3, 3/5)

c. 1/5x = y

Step-by-step explanation:

Remember: (x, y)

0.5 = 1/2

(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.

1 2/5 = 7/5

(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.

Step-by-step explanation:

Answer:

$0.1 /lb.

Step-by-step explanation:

First, divide 1.99 by 19. You get 0.1047368421. To round it to the nearest hundred, look to the number 3 points away from the decimal, which is number 4. Since it is not 5 or greater, we round it down, and it would round down to 0.1.

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:

20

Step-by-step explanation:

we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20

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

===============================

Work Shown:

2x+108 = 180

2x+108-108 = 180-108

2x = 72

2x/2 = 72/2

x = 36

-------

Notes:

Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .

To Find : The value of x .

Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;

[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]

⇒ 2x° + 108° = 180° .

⇒ 2x° = 180° - 108° .

⇒2x° = 72°.

⇒ x =[tex]\sf \dfrac{72}{2}[/tex]

⇒ x = 36° .

Hence the value of x is 36° .

Answer:

21 kids have to go on the trip to make the museum a better deal

Step-by-step explanation:

Zoo: y=10x+100

Museum: y=5x+200

10x+100=5x+200

5x=100

x=20

When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

Answer:

-50

Step-by-step explanation:

A negitive number would mean debt or owed. A positive number would be a credit of a number.

Answer:

A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x–2" (pronounced as "ecks to the minus two") just means "x2, but underneath, as in 1 x 2 \frac{1}{x^2} x21 ".
