A water truck is filling a swimming pool. The equation that represents this relationship is y = 19.75x where y is the number of gallons of water in the pool and x is the number of minutes the truck has been filling the pool. Choose True or False for each statement.

If x is the first integer, then the fourth integer is x + 3. The sum of these is 33, so

x + (x + 3) = 33

2x + 3 = 33

2x = 30

x = 15

Answer:

Step-by-step explanation:

x=15

Answer:

112

Step-by-step explanation:

Supplementary angles means that angle A and angle B added together equal 180˚. This mean we can re-write the angle measures into an algebra problem

A(3x+16) + B(2x + 4 ) = 180

Or

5x + 20 = 180

5x + 20 - 20 = 180 - 20

5x = 160

5x/5 = 160/5

x = 32

Now that we know that X = 32, we can plug 32 into the measure of angle A.

A(3x+16)

A(3(32)+16)

A(96+16)

A(112)

Angle A equals 112˚ and Angle B equals 68˚.

Answer: x^2+x-12 = 0 ⇒ x = -4 or x = 3 and x^2-6x+9 = 0 ⇒ x= 3

x^2+x-12 = 0 (Find two numbers that add to 1 and multiply to -12)

x^2-3x+4x-12 = 0 (Factor out like terms)

x(x-3)+4(x-3) = 0 (Group common terms)

(x-3)(x+4) = 0 (Set each term to equal 0 and solve for x)

∴ x = -4 or x = 3

x^2-6x+9 = 0 (It's a perfect square trinomial)

(x-3)^2 = 0

∴ x = 3

Answer: x = -4 and x = 3 for the first one. x- 3 for the second one.

Answer:

He would walk 20 miles in 5 hours.

Step-by-step explanation:

Mo walked 20 miles in 5 hours.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Mo walked 12 miles in 3 hours.

In 1 hour Mo walked= 12/3

                               = 4 miles

and, in 5 hours Mo walked

= 5 x 4

= 20 miles.

Hence, Mo walked 20 miles in 5 hours.

Answer:[tex](-7-2)=-3(-3-0)[/tex]

Step-by-step explanation:

First use slope intercept form to find the value of b (the y intercept). The slope intercept formula is

[tex]y=mx+b[/tex]

Since we are given the point (-3,2), we can say that y=2 and x=-3. m=-3. Then we get

[tex]2=-3(-3)+b[/tex]

[tex]2=9+b[/tex]

[tex]b=-7[/tex]

Since we now have the y intercept, we can convert it to a point: (0,-7). Plug this into the point slope equation:

[tex](y_{1}-y_{2})=m(x_{1}-x_{2})[/tex]

Our first point is (-3,2). Our second point is (0,-7). Therefore:

[tex]x_{1}=-3\\y_{1}=2\\x_{2}=0\\y_{2}=-7\\m=-3[/tex]

Plugging into the equation, we get

[tex](-7-2)=-3(-3-0)[/tex]

Answer:

x=0.1

Step-by-step explanation:

2x+1+=19

19-1=18

2x=18

2/18=0.1

x=0.1

Answer:

x= 9

Step-by-step explanation:

First I would subtract the 1 from 19 which leaves me with 18 then divide both sides by 2 so 2x/2 = 18/2 which gives me 9 now to check. 2 multiplied by 9 =18 plus 1 =1 9. and thats how I get the answ.r

Answer: C, B, A, D

Step-by-step explanation:

1. option C

f(x) = 2x² - 1

f(-1) = 2(-1)² - 1

     = 2(1) - 1

     = 2  - 1

     =   1

2. option B

f(x) = 2x - 5

11  = 2x - 5

16 = 2x

8 = x

3. option A

f(x) = 2x - 5

f(3) = 2(3) - 5

     = 6 - 5

     =   1

4. option D

f(x) = x² + 7

f(-2) = (-2)² + 7

      =   4 + 7

Answer:

what is the question

Step-by-step explanation:

Answer:

15 ounces per box

Step-by-step explanation:

What is the weight, in ounces, of one box?

165ounces/ 11 boxes

This means

165ounces per 11 boxes

Hence:

11 boxes = 165ounces

1 boxes = x ounces

Cross Multiply

11x = 165 × 1

x = 165/11

x = 15 ounces

Therefore, the weight, in ounces, of one box is 15 ounces per box.

Answer:

15 ounces per box

Even when the answer is not complete, most likely yes, she was cheated.

Step-by-step explanation:

The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.

So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.

Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:

If 6 eggs per packet:

46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.

If 12 eggs per packet:

46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.

That's why it is safe to assume some packets had less eggs than expected.
