Answer:
j=1/2k+5/2
Step-by-step explanation:
2j−k=5
Step 1: Add k to both sides.
2j−k+k=5+k
2j=k+5
Step 2: Divide both sides by 2.
2j/2=k+5/2
j=1/2k+5/2
Answer:
$7 for an adult ticket
$6 for a child ticket
Step-by-step explanation:
Add up the total child and adult tickets from both the days.
Adult tickets - 15
Child tickets- 10
Then I divided 165 but 25 and got 6.6.
The child ticket should be less than the adult so I guessed that the adult would be around $7 and the child ticket would be around 6.
I double checked my work by doing...
3*7 giving me 21
and
9*6 giving me 54.
Then I added these up to get $75 which was the total from the first day. This shows that our answer is correct
Answer:
x = 5
Step-by-step explanation:
(2x+2)² - (2x)² = 44
4x^2 + 8x + 4 - 4x^2 = 44
8x + 4 = 44
8x = 44 - 4
8x = 40
x = 40/8
x = 5

Step-by-step explanation:
Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318
