Enter the value of x that makes the equation 5+3x-37=6x+23-8x
Answer:
x=-7
Step-by-step explanation:
Answer:
x=11
Step-by-step explanation:
5+3x-37=6x+23-8x
add like terms
-32+3x=-2x+23
add 2x to both sides
-32+3x+2x=23
add 32 to both sides

The budget for a middle school dance is $750. Food and decorations cost $175. The DJ charges $75 per hour plus a one-time business fee of $125?
What is the maximum number of hours the school can have the DJ play at the dance?
Answer:
The DJ can play at the dance for 6 Hours
Step-by-step explanation:
1. Add the decorations and food plus the additional fee of $12
$175+ $125= $300
2. Subtract the budget and the total so far
750-300= 450
3. Get the amount owed per hour to DJ and divide by the new budget
450/75= 6
The DJ can play at the dance for 6 hours
Have a good day!

5 x 3/5 = 3 (the whole number 5 and the denominator of 5 cancel each other out)

A rectangular chocolate bar is made of equal squares. Irena breaks off two complete strips of squares and eats the 12 squares she obtains. Later, Jack breaks off one complete strip of squares from the same bar and eats the 9 squares he obtains. How many squares of chocolate are left in the bar?
Answer:
There are three more square chocolates left
Step-by-step explanation:
We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)
The number of Squares of chocolate left in the bar is; 15 squares
What is the amount of squares left?
A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.
It means that each of the vertical height must also contain 6 squares as well.
Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.
Now, Jack ate 9 squares and so;
Amount of squares left = 25 - 9 = 15

b-7=12
Answer:
[tex]b = 19[/tex]
Step-by-step explanation:
1) Add 7 to both sides.
[tex]b = 12 + 7[/tex]
2) Simplify 12 + 7 to 19.
[tex]b = 19[/tex]
Therefor the answer is, b = 19.
Answer:
Sample Response
Step-by-step explanation:
Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.

four thousand three hundred twenty-one ten thousandths as a decimal
Answer:
.4321
Step-by-step explanation:
move the decimal to the left four times
We want to write four thousand three hundred twenty-one ten thousandths as a decimal.
The number is:
4321.010
To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.
The first digit at the left of the decimal point represents the units.The second digit at the left of the decimal point represents the tens.The third digit at the left of the decimal point represents the hundreds.The fourth digit at the left of the decimal point represents the thousands.
And for the right we have:
The first digit at the right of the decimal point represents the tenths.The second digit at the right of the decimal point represents the hundredths.The third represents the thousandths.Of course, it continues in both ways, but this is enough to write our number.
We have:
"four thousand..."
Then the fourth digit at the left is a 4.
"... three hundred..."
The third digit is a 3.
"...twenty-one..."
The second digit is a 2, and the first is a 1.
For the right side, we do not have tenths, so the first digit at the right is a zero.
And "...ten thousandths"
We have a "10" in the second and third digits at the right of the decimal point.
Then our number is:
4321.010
