Answer:

It is a solution to the equation

Step-by-step explanation:

We just need to bring the value 9 to the right hand side of the equation

So we have;

x = 17 -9

x = 8

Answer:

9/4 cups or 2 1/4 cups.

Step-by-step explanation:

Since she uses 3/4 for every 2 cups, then we have to find out what she makes per cup. We have to divide 3/4 in half and to do that, we want to scale up 3/4 making it 6/8 which is congruent to 3/4.

Now we divide 6/8 in half which is 3/8.

Then we multiply that by 3, 6 times 3 is 18. So now it is 18/8 cups. We can now scale down and simplify it more.

To do that, we just divide the fraction by 2 to make to denominator into 4. Because of that, our answer is 9/4 cups or 2 cups and 1/4 cup.

Cups of rice uses for every 3 cup of milk is [tex]1\frac{1}{8}[/tex] cups

Given:

Cups of rice uses for every 2 cup of milk = 3/4 cup

Find:

Cups of rice uses for every 3 cup of milk

Computation:

Cups of rice uses for every 1 cup of milk = (3/4) / 2

Cups of rice uses for every 3 cup of milk = [3 / 8]3

Cups of rice uses for every 3 cup of milk = 9 / 8

Cups of rice uses for every 3 cup of milk = [tex]1\frac{1}{8}[/tex] cups

Answer:

Option B.

Step-by-step explanation:

Let 'g' represent the number of gallons of cleaning solutions.

Let 'c' represent the number of cups of bleach.

From the question given above, we were told that:

To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.

This implies that number of gallons (g) of the cleaning solution is directly proportional to the number of cups (c) of the bleach mixed with water i.e

g ∝ c

g = Kc

K is the constant of proportionality.

Next, we shall determine the relationship between g and c as follow

g = 5

c = 3

K =?

g = Kc

5 = K × 3

Divide both side by 3

K = 5/3

g = Kc

K = 5/3

g = 5/3 c

Thus, the relationship between g and c is:

g = 5c / 3

Next, we shall make c the subject of the formula. This is illustrated below:

g = 5c / 3

Cross multiply

3g = 5c

Divide both side by c

c = 3g/5

Next, we shall determine c when g = 10, 15, and 20.

This is illustrated below:

g = 10

c =?

c = 3g/5

c = (3 × 10)/5 = 30/5 = 6

g = 15

c =?

c = 3g/5

c = (3 × 15)/5 = 45/5 = 9

g = 20

c =?

c = 3g/5

c = (3 × 20)/5 = 60/5 = 12

Summary:

Num. of gallon (g) >> Num. of cup (c)

5 >>>>>>>>>>>>>>>> 3

10 >>>>>>>>>>>>>>> 6

15 >>>>>>>>>>>>>>> 9

20 >>>>>>>>>>>>>>> 12

Therefore, option B gives the correct table.

Answer:

The dimensions of the garden are 22.5ft by 27.5ft

Step-by-step explanation:

Here, we want to calculate the dimensions of the garden.

let the length be x ft

we are told that the he wants the length to be 5 feet more than the width;

That means the width will be (x-5) ft

Mathematically;

Since the shape is rectangular, the perimeter will be 2( l + w)

Thus; 2(x + x-5) = 100

2(2x-5) = 100

divide both sides by 2

2x-5 = 50

2x = 50 + 5

2x = 55

x = 55/2

x = 27.5 ft

The width is thus; 27.5ft - 5ft = 22.5ft

the dimensions of the garden are 27.5 ft by 22.5 ft

Answer:

  x = 21

Step-by-step explanation:

The angle T is an exterior angle to the ∆RST, so will be equal to the sum of the remote interior angles:

  T = 4x° +2x° = 6x°

T is also a same-side exterior angle with the one marked 54°, so is supplementary to that:

  T + 54° = 180°

  6x° + 54° = 180°

  x + 9 = 30 . . . . . . . . divide by 6

  x = 21 . . . . . . . . . . . . subtract 9

_____

Check

The triangle angles are ...

  4x = 84°

  2x = 42°

  unmarked = 54°

Their sum is 84° +42° +54° = 180° . . . as it should be.

Answer:

the answer is 144 feet

Step-by-step explanation:

to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12

to find the area of the square you do A= lw which in this case it would look something like this:

A= 12(12) you use 12 twice because square sides are always equal

then you multiply which gives you A= 144

Answer:

Step-by-step explanation:

The system of equation given is a simultaneous equation

7x + 2y = 24 ...... 1

2x + 1 = y ......... 2

Rearrange

7x + 2y = 24  .... *1

| 2x - y = -1 ..... * 2

Use elimination method

7x + 2y = 24

4x - 2y = -2

add

7x+4x = 24-2

11x = 22

x = 22/11

x = 2

Substitute x = 2 into 2

2x+1 = y

y 2(2)+1

y = 4+1

y = 5

Hence x = 2, y = 5

The system of equation is a simultaneous equation

Answer:

D. y=2/3x+4

Step-by-step explanation:

4 is the y-intercept, and the line goes up 2 on the y-axis for every 3 it goes up on the x-axis.

a = 17

b = 18

c = 19

Hi there !

a + b + c = 54

b = a + 1

c = a + 2

replace b ; c

a  + (a + 1) + (a + 2) = 54

3a = 54 - 3

3a = 51

a = 51 : 3

a = 17

b = 18

c = 19

Good luck !

y=2/3x-2

Step-by-step explanation:

A linear equation is in the form of y=mx+b

You need to find the slope and y-intercept.

The slope is 2/3  Up 2, over 3 to the right.

The y-intercept is (0,-2)

So the equation would be, y=2/3x-2
