8 0

Answer:

The 8 should have remained positive.

Step-by-step explanation:

8-(-2)=8+2=10

Two negatives make a positive so 8-(-2) will turn into 8+2.

Laura was wrong because she thought the 8 turned to a negative but that makes no sense.

What the answer for 14+1/7x=28
const2013 [10]

Answer:

98

Step-by-step explanation:

Subtract 14 from both sides (14-14 and 28-14)

The equation is now 1/7x=14

From here you have to get rid of the denominator of 1/7x so to cancel it out you must multiply both sides by 7.

1/7x · 7 = 1x

14 · 7 = 98

You then have the answer which is x = 98

Mr.Johnson purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under
taurus [48]

Answer:

15

Step-by-step explanation:

Let the number of adult tickets be x while children ticket be y. Since the total tickets were 20 then we can form the equation

x+y=20

Making x the subject then x=20-y

Considering the cost of each ticket

15x+10y=225

Substituting x with 20-y then

15(20-y)+10y=225

300-15y+10y=225

Collecting like terms

300-225=15y-10y

75=5y

Y=75/5=15

To find x, we already know that x=20-y hence x=20-15=5

Therefore, children tickets are 15 while adult tickets are 5.

The question only needs us to know the children tickets, y which is 15
