Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation representing the
budget for the trip is 240 = 12x + 8y. Here is a graph of this equation.

The number of children that will be able to go to the zoo is 18.

"The missing question;

How many children will be able to go to the zoo if 8 adult tickets are purchased ?

The given parameters;

The equation representing the budget for the trip;

12x + 8y = 240

When 8 adult tickets are purchased, the possible number of children to be accommodated within the budget is calculated as follows;

12(8) + 8y = 240

96 + 8y = 240

8y = 240 - 96

8y = 144

Thus, the number of children that will be able to go to the zoo is 18.

Step-by-step explanation:

Given

Required

Plot a graph

First, we need to determine the minimum and maximum values of x and y

For x:

Minimum = 0

For maximum; Let y = 0

Solve for x

For y:

Minimum = 0

For maximum; Let x = 0

Solve for y

See Attachment for graph

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
