To answer the question, let x be the number of adults going to the zoo and 2x be the number of children. The total amount gained from the ticket sales should be,
                             1650 = 6x + 4(2x)
The values of x is equal to 117.86. Therefore, the school bought approximately 118 tickets for adults and 236 for children.

a submarine is 100 meters below sea level when it begins to ascend at a steady rate of 3.0 miles per minute interpret values wha
Angelina_Jolie [31]

Answer:

y = 3x - 100

Step-by-step explanation:

below signifies that the 100 is negative

so we already know that the submarine is starting at -100 meters, which is going to be the y-intercept

ascend means to rise up signifying that the slope is going to be positive and we already know that the submarine is ascending 3 miles per minute

so the equation would look like this:

y = 3x - 100

10. Jack’s mom gave him 50 chocolates. At Jack’s party, he gave each of his friends 6 chocolates. Unfortunately Jack was 4 piece
ASHA 777 [7]

Answer:

see below

Step-by-step explanation:

Let f = number of friends

all but one friend got 6 pieces   and 1 friend got 2  for a total of 50 pieces

6(f-1) + 2 = 50

Subtract 2 from each side

6(f-1) +2-2 = 50-2

6(f-1) = 48

Divide by 6

6(f-1)/6 = 48/6

f-1 = 8

Add 1 to each side

f-1+1=8+1

f=9

Jack has 9 friends at the party

With Jack and his mom, there are 11 people

The area of circle Z is 64 ft^2.
Nutka1998 [239]

Answer:

The answer is

<h2>r =4 ft</h2>

Step-by-step explanation:

Area of a circle is given by πr²

Where r is the radius

From the question

Area = 64 ft²

So the radius is

64 = πr²

Divide both sides by π

{r}^{2}  =  \frac{64}{\pi}

Find the square root of both sides

r =  \sqrt{ \frac{64}{\pi} }

r = 4 ft

Hope this helps you

Substitute the known value of x​ into y=4x+20​. Then solve for y entering the equation in simplest form
scoray [572]

Answer:

y=24, when x=1.

Step-by-step explanation:

Given: y=4x+20

To find: Value of y, substituting the known value of x

We have,

y=4x+20 ...(i)

Putting x=1 in equation (i), we get

y=4(1)+20

\implies y=4+20

\implies y=24  

Hence, the value of y is 24, when the value of x is 1.
