Hi! I hope you're enjoying your day!
The missing number is 5.
Why 5? You'll see...
So the equation is
5x+15=5x-3
Is this right? We need to check.
Let's plug in 1.
5(1)+15=5(1)-3
5+15=5-3
20=-2
See? We ended up with a false statement.
There's no way 20 is going to equal -2.
Let's try 2:
5(2)+15=5(2)-3
10+15=10-3
25=7
Once again, we have a false statement.
You could try any number. You could try 5, 12, 150, 2710...
No matter which number you choose, you will always have a false statement.
Hence, the missing number is
[tex]\boxed{\boxed{\bold{5}}}[/tex]
But hey!! Why 5?!
Because no matter which number you pick, you will always have a false statement.
There's no number that can satisfy the following equation:
5x+15=5x-3
Basically, you take a number x, multiply it times 5, add 15, and that's supposed to equal the same number times 5 and minus 3?!
Hope everything is clear.
If you have any questions, please ask.

2.50x+3.00y=?
x=8 y=11
Answer:
The cost of popcorn per container = $2.50
The cost of bottle of juice each = $ 3.00
(Now multiple it)
2.50 x 8 = $20.00
3 x 11 = $33
(Now "+" the both answer that we multiple)
$20.00 + $33 = $53
(So we know how much she spend)
Therefore She spend $20 on popcorn per container and $33 on bottle of juice, so total she spend $53 for both popcorn and bottle of juice.

Christopher buys 200 baseball cards to start a collection. He purchases 50 more baseball cards each week. Write an equation to represent the number of baseball cards (b) in Christopher’s collection after w weeks? How many cards does he have after 5 weeks?
Answers
Answer: equation is 200b + (50b · w). He will have 450 cards in 5 weeks.
Explanation: 50 baseball cards (b) times w then you add the cards he already has, which is 200. To answer question b, w becomes 5, so then it’s 50 baseball cards (b) times 5, which is 250b, then you add 200 (the cards he already has) and the answer is 450. Hope this helped!
Answer: 450 cards

Answer:
angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.
angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.
x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32
angle a is 136 described above.
angle b, because it is on the same line as the 46 degree angle is 180-46=134

Which inequality does this graph show?
Answers
Answer:
D
Step-by-step explanation:
We can find two clear points. (2.5, -0.5) and (4, 0). The slope is 1/3. So our equation is y=(1/3)x + ?. We can figure out the y-intercept by inputting a point. For example, if we input (4,0), we have 0=(4/3)x + ?. So our y-intercept is -4/3. Our equation is y=(1/3)x-4/3. Rearrange and we have y-(1/3)x=-4/3. We multiply 3 to get rid of fractions. 3y-x=-4. Therefore the equation of the line is 3y-x=-4. Now for the inequality part: The shading is BELOW and the line is bolded (not dotted) so it would be "less than or equal to". So, the inequality of the graph would be 3y-x≤-4.

Laura started a race at 6:39 PM and finished it at 7:15 PM.
How long did it take her? Give your answer in minutes.
Answers
Answer:
36 mins
Step-by-step explanation:
7:15 - 6:39 = 36 mins
She finished the race in 36 mins.
Have a good day/night
Answer:
36 minutes
Step-by-step explanation:
You subtract the time she started from the time she finished.
So, it would be 7:15 - 6:39.
It would be easier to find the number that, when added to 6:39, results to 7:00.
To do so, you subtract 39 from 60.
60 - 39 = 21 minutes
Now, add 21 to 15.
21 + 15 = 36 minutes
Therefore, it took her 36 minutes to complete the race.
Hope this helps!

Answer:
1
Step-by-step explanation:
Equations to remember:
Length · Width · Height = Volume
LWH = V
---------------------------------------------------
Length = 5/4
Width = 4/3
Height = 3/5
Your equation will look something like this:
[tex]\frac{5}{4} * \frac{4}{3} * \frac{3}{5} = V[/tex]
or
[tex]\frac{5*4*3}{4*3*5} = V[/tex]
----------------------------------------------------
The simple thing about this problem is that, no matter what order they're in, you're multiplying the same numbers on the top and the bottom. Whatever the top is (5*4*3), the bottom will be (4*3*5). If the top and bottom are equal, that means that you'll have a whole number of 1.
----------------------------------------------------
NOMINATORS
[tex]5 * 4 = 20\\20 * 3 = 60[/tex]
So the top will be 60.
----------------------------------------------------
DENOMINATORS
[tex]4 * 3 = 12\\12 * 5 = 60[/tex]
The bottom will also be 60.
-----------------------------------------------------
[tex]\frac{60}{60} = \frac{1}{1} = 1[/tex]
So your answer will be [tex]1cm^{3}[/tex]!

5 1/4 - 2 5/7 = ____
Answers
Answer:
5 1/4 - 2 5/7 = ______
5 - 2 = 3
1/4 = 7/28
5/7 = 20/28
7/28 - 20/28 = -13/28
3 -13/28 = 2 15/28
5 1/4 - 2 5/7 = 2 15/28
Answer: 2 15/28
Step one: Put aside the whole numbers for now. We will be dealing with the fractions. We have to make a common denominator! The smallest common denominator of 4 and 7 is 28. So we need to multiply 1/4 by 7 and 5/7 by 4, which would be 7/28 and 20/28.
Step two: now we can subtract them. Finally!
4 35/28 - 2 20/28 will be 2 and 15/28!!
