87. Juanita started with 40 dollars in her pocket.
Then she bought one CD for 7.99 dollars and 1 DVD for 8.99 dollars.
It has a sales tax of 7% on these items.
Plus she bought a lunch for 4.25 dollars including tax
Solve:
=> 7.99 dollars + 8.99 dollars = 16.98 dollars
=> 16.98 dollars * .07 = 1.2 dollars
=> 16.98 + 1.2 = 18.18 dollars
Plus the lunch
=> 18.18 + 4.25 = 22.43 dollars
=> 40 – 22.43 = 17.57 dollars
Answer:
16 players can be brought to the tournament. The equation is written within my step-by-step explanation.
Step-by-step explanation:
Variable p = number of players
Set up an equation:
974.50 + 60.75p = 1946.50
Isolate variable p:
60.75p = 972
Divide:
p = 16
Check your work:
974.50 + 60.75(16) = 1946.50
974.50 + 972 = 1946.50
1946.50 = 1946.50
Correct!
3 miles per hour. Theres 4 hours between 9 am and 12 and another 6 from 1to 6.so ten hours. then 12.8 plus 17.8 thats 30 then 30 divided by ten is 3 miles per hour. Your welcome :)
The value of 4 in 2,402 is 400(four-hundred) and in 64,513 its 4,000(four-thousand)
Part 1
Answer: -9
---------------------------
Explanation:
Let's focus on evaluating first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5
This means f(5) = 13 and The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.
<em>We can replace all of </em>
<em> </em>
<em> with 5 to go from </em>
<em> to </em>
<em> </em>
<em>Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9.</em>
<em>So f(-9) = 5 and </em>
<em>Overall, </em>
===============================================
Part 2
Answer: -13
---------------------------
Explanation:
Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13
<em>This means f(-13) = 8 and </em>
