Answer:

See below.

Step-by-step explanation:

Substitute the value for the variable and solve.

a.)

⇒ y = -5(3) + 17

⇒ y = -15 + 17

⇒ y = 2

b.)

⇒ y = 3(3) - 22

⇒ y = 9 - 22

⇒ y = -13

c.)

⇒ y = 2(3) - 25

⇒ y = 6 - 25

⇒ y = -19

d.)

⇒ y = 6(3) - 39

⇒ y = 18 - 39

⇒ y = -21

X changes to Multiply symbol

Step-by-step explanation:

-5 X 3 + 17

-5 X 3 = -15

-15 + 17 = 2

3 X 3 - 22

3 X 3 = 9

9 - 22 = 13

2 X 3 -25

2 X 3 = 6

6 - 25 = 19

6 X 3 - 39

6 X 3 = 18

18 - 39 = -21

Solve for w. 8(w+2) = 40

AleksAgata [21]

Answer:

w = 3

Step-by-step explanation:

8 • (w + 2) - 40 = 0

Pulling out like terms :

3.1 Pull out like factors :

8w - 24 = 8 • (w - 3)

Equation at the end of step 3 :

8 • (w - 3) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 8 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : w-3 = 0

Add 3 to both sides of the equation :

w = 3

One solution was found :

w = 3

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day 333 people enter the park, the

liberstina [14]

Answer:

188 children and 145 adults were admitted in the park.

Step-by-step explanation:

Given:

The admission fee at an amusement park is $1.50 for children and $4 for adults.

Total $862 collected on a certain day when 333 people enter the park.

Now, to find the children and adults admitted in the park.

Let the number of children admitted be $x.$

And the the number of adults admitted be $y.$

So, the total people enter the park:

$x+y=333\\\\x=333-y\ \ \ ...(1)$

Thus, the total amount collected of the admission fee:

$1.50(x)+4(y)=862\\\\$

Substituting the value of $x$ from equation (1):

$1.50(333-y)+4(y)=862\\\\499.50-1.50y+4y=862\\\\499.50+2.50y=862\\\\Subtracting\ both\ sides\ by\ 499.50\ we\ get:\\\\2.50y=362.50\\\\Dividing\ both\ sides\ by\ 2.50\ we\ get:\\\\y=145.$

Thus, the number of adults = 145.

Now, to get the number of children by substituting the value of $y$ in equation (1) we get:

$x=333-y\\\\x=333-145\\\\x=188.$

Hence, the number of children = 188.

Therefore, 188 children and 145 adults were admitted in the park.
