If f(2) = 22 – 5, then what is the value of f(2) + f(5)?
Answer:
67
Step-by-step explanation:
With the information of f(2) = 22-5, you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67
Which expression is equivalent to
Answer:
a
Step-by-step explanation:
(5x+6) over 2 = 3 (4x+12)
x= -66/19
Multiply 2 on both sides:
2*(5x+6)/2=3(4x+12)*2
Simplify:
5x+6=24x+72
Subtract 6 from both sides:
5x+6-6=24x+72-6
Simplify:
5x=24x+66
Subtract 24x from both sides:
5x-24x=24x+66-24x
Simplify:
-19x=66
Divide both sides by -19
-19x/-19=66/-19
Simplify:
x= -66/19
Laurie earns $7.50 per hour at the fruit stand plus an extra $2.00 per hour on Sundays. One week in August, she worked on Sunday, Monday, and Wednesday. She worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, how many hours did Laurie work on Monday? Enter and solve an equation.
Answer:
Hi there!
Your answer is:
She worked for 3 Hours on Monday.
Step-by-step explanation:
7.5$ per hour
7.5+2$ per hour on Sundays.
In August:
Sunday, Monday, Wednesday.
# of hours for Monday =Wednesday
Sunday= 4 hrs (which would mean 9.5$ * 4)
Monday and Wednesday will be modeled by X
X + 38$ (earned sunday)= 83$
-38
X= 45$
Since X represents BOTH monday and wednesday, divide by 2
45/2 = 22.5$
CHECK YOUR WORK
22.5$ (monday) + 22.5$ (wednesday) + 38$ (sunday)= 83???
45=38=83???
83=83 YES
Now, to determine how many hours that is, we divide the earned wages by the wage per hour.
22.5 / 7.5 = 3 HOURS
CHECK YOUR WORK
3 hours * 7.5 per hour = 22.5???
22.5 = 22.5 YES
Hope this helps
If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours
$7.5= 1 hour Other days
$9.50 or ($7.50+$2.00) = 1 hour Sunday
Let Sunday= 4×$9.50 =$38
Let Monday= x × $7.5=$7.5x
Let Wednesday= x × $7.5=$7.5x
Let Total earning=$83
Let x represent the number of hours
Hence:
First step is to formulate
7.5x+7.5x+38=83
Second step is to calculate how many hours did Laurie work on Monday
x =83-38÷ 7.5+7.5
x=83-38÷15
x=45÷15
x=3 hours
Inconclusion If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours

Chris wants to order DVDS over the internet. Each DVD costs $ 15.99 and shipping for the entire order is $ 9.99. How much will Chris spend (s) if he buys x DVDS?
Answer:
There are 3 DVD s that can be bought with under $100.
Step-by-step explanation:
Since we have given that
Cost of DVD = $15.99
Cost of Shipping = $ 9.99
Total cost per DVD would be
$15.99 + $9.99 = $ 25.98
Amount he has to spend no more than $ 100.
So, number of DVDs would be
100 ÷ 25.98 = 3.84
Hence, there are 3 DVD s that can be bought with under $100.

216 divided by 31
Please give me the answer AND the remainder. i DO NOT want the answer in deciamls
And show your work
Answer:
6 r 30
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 31 on the left side and the dividend 216 on the right side like this:
3 1 ⟌ 2 1 6
Step 2:
The divisor (31) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
3 1 ⟌ 2 1 6
Step 3:
Multiply the divisor by the result in the previous step (31 x 0 = 0) and write that answer below the dividend.
0
3 1 ⟌ 2 1 6
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
3 1 ⟌ 2 1 6
- 0
2
Step 5:
Move down the 2nd digit of the dividend (1) like this:
0
3 1 ⟌ 2 1 6
- 0
2 1
Step 6:
The divisor (31) goes into the bottom number (21), 0 time(s). Therefore, put 0 on top:
0 0
3 1 ⟌ 2 1 6
- 0
2 1
Step 7:
Multiply the divisor by the result in the previous step (31 x 0 = 0) and write that answer at the bottom:
0 0
3 1 ⟌ 2 1 6
- 0
2 1
0
Step 8:
Subtract the result in the previous step from the number written above it. (21 - 0 = 21) and write the answer at the bottom.
0 0
3 1 ⟌ 2 1 6
- 0
2 1
- 0
2 1
Step 9:
Move down the last digit of the dividend (6) like this:
0 0
3 1 ⟌ 2 1 6
- 0
2 1
- 0
2 1 6
Step 10:
The divisor (31) goes into the bottom number (216), 6 time(s). Therefore put 6 on top:
0 0 6
3 1 ⟌ 2 1 6
- 0
2 1
- 0
2 1 6
Step 11:
Multiply the divisor by the result in the previous step (31 x 6 = 186) and write the answer at the bottom:
0 0 6
3 1 ⟌ 2 1 6
- 0
2 1
- 0
2 1 6
1 8 6
Step 12:
Subtract the result in the previous step from the number written above it. (216 - 186 = 30) and write the answer at the bottom.
0 0 6
3 1 ⟌ 2 1 6
- 0
2 1
- 0
2 1 6
- 1 8 6
3 0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 216 divided by 31 calculated using Long Division is:

Akiko wants to fence in her [tex]12[/tex] ft by [tex]10[/tex] ft vegetable garden. There will be a path [tex]x[/tex] ft wide between the garden and the fence. The area to be enclosed by the fence will be [tex]360[/tex] sq ft. Write a quadratic function that can be used to determine the value of [tex]x[/tex].
Answer:
see below
Step-by-step explanation:
The length is 12 + 2x and the width is 10 + 2x
A = l*w
360 = ( 12+2x) ( 10+2x)
FOIL
360 = 120 + 24x+20x + 4x^2
Combine like terms
360 = 4x^2 +44x+120
Subtract 360 from each side
0 = 4x^2 +44x +120-360
0 = 4x^2+ 44x -240
For fun, lets solve
0 = 4( x^2 + 11x - 60)
0 = 4( x+15) ( x-4)
Using the zero product property
x= -15 x=4
Since we cannot have negative length
x=4 ft
Answer:
[tex]x^2+11x-60=0[/tex]
Step-by-step explanation:
Refer to the drawing.
We know that the area enclosed by the fence is 360 square feet. Remember that the area for a rectangle is given by the following formula:
[tex]A=bh[/tex]
So, let's substitute 360 for A, (12+2x) for b, and (10+2x) for h. This yields:
[tex]360=(12+2x)(10+2x)[/tex]
We can simplify this. On the right, factor out a 2 from the first term and a 2 from the second. This yields:
[tex]360=2(6+x)\cdot2(5+x)[/tex]
Multiply:
[tex]360=4(x+6)(x+5)[/tex]
Divide both sides by 4:
[tex]90=(x+6)(x+5)[/tex]
Multiply on the right:
[tex]90=x^2+6x+5x+30[/tex]
Add on the right:
[tex]90=x^2+11x+30[/tex]
Subtract 90 from both sides. So, our equation is:
[tex]x^2+11x-60=0[/tex]
And we're done!
