Rearrange the 2nd equation

-36a-24b-16c

divide the whole thing by 4 and you'll get
-9a-6b-4c

you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7

multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28

so the answer you want is -28

<h3><u>Answers in Step-By-Step</u></h3>

Step-by-step explanation:

A; the admission price is $15

For adults its 2x

For students its x

and for children under 3 years old its 1/2x

to find the weekend money replace "x" with 15 as the money.

Adults: 2 * 15

students: 15

infants: 1/2 * 15

Do the math

2 * 15 = 30

15 = 15

1/2 * 15 = 7.5

B; A group of 4 adults, 5 students, and 2 children under the age of 3 visits the theme park on Sunday.

for each adult is $30

each student is $15

and children under 3 is $7.50

Do the math

30 * 4 = 120

15 * 5 = 75

2 * 7.5 = 15

120 + 75 + 15 = $210

C; If a student's weekday cost's $18, find the total admission cost that group B) has to pay.

Adult: 18 * 2

Student: 18

infant: 1/2 * 18

do the math

18 * 2 = 36

18 = 18

1/2 * 18 = 9

each adult is $36

each Student is $18

each infant is $9

4 adults, 5 students, 2 children under 3

4 * 36 = 144

5 * 18 = 90

9 * 2 = 18

144 + 90 + 18 = 252

The total would come out to $252

At the store Janet purchased 1.5 pounds of ham for $4.99 per pound and 0.75 pounds for $2.50 per pound. If she gave the cashier
Citrus2011 [14]

Answer:

She will receive 64 cents in change.

Step-by-step explanation:

Cost per pound of ham = $4.99

Pounds bought = 1.5

Cost of 1.5 pounds = 4.99 * 1.5 = $7.485

Cost per pound of other item = $2.50

Pounds bought = 0.75

Cost of 0.75 pounds = 0.75 * 2.50 = $1.875

Total = 7.485 + 1.875 = $9.36

Amount paid = $10

Change received = 10 - 9.36 = $0.64

Therefore,

She will receive 64 cents in change.
