195 students went on a field trip, 21 students rode in cars and the rest of the students filled
six buses. How many students were in each bus?
Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
Answer:
29 students in each bus
Step-by-step explanation:
at first, 21 students rode by car. so the remaining students are 195-21=174 students.
Now if we divide the remaining number of students by the number of buses then,
[tex] \frac{174}{6} = 29[/tex]
which is 29 students in each bus.

Jason owns a cabin that he rents to people for a maximum of 21 nights. He uses the function f(x) = 175x + 50 to calculate the rental cost for nightsWhat is the domain for the function in this context?
Answer:
domain: all natural numbers greater than zero and less than or equal to 21

Please help with answer solution clearly shown--thx!
Answer:
Step-by-step explanation:
First you have to multiply both sides by 4
4 (3x - 1) by 4 > 3 x 4
Then simplify it:
3x-1 > 12
Now add one to both sides
3x - 1 + 1 > 12 + 1
Then simplify it again:
3x > 13
Now divide both sides by 3
3x ÷ 3 > 13 ÷ 3
Answer:
x = 13 ÷ 3

Answer:
-8x² - 6
Step-by-step explanation:
-1 + 2 will give us "+1"
+1 - 7 will give us "-6"
The answers given already are correct as they are properly matched, so we are left with the following to complete:
Thus,
-4y³ + 4y³ will give us "0".
We would be left with:
-3x² - 6 - 5x²
Collect like terms again
-3x² - 5x² - 6
-3x² - 5x² will give us "-8x²"
Final result would be:
-8x² - 6

Step-by-step explanation:
3360832553 ____ pass___ wZE2XQ
Answer:
See the attached picture.
Step-by-step explanation:
I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.
See the attached picture.
There are 2 x's on the left and 4 1's on the right.
This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.
Each unit of different size should be in a different shape.
The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.
Hope this helps.

Answer:
the answer is D
Step-by-step explanation:
The values of x and y are directly and one pair of values are given.
write an equation that relates x and y. simplify completely.
x= -4, y =6
Answer:
The relation is [tex]y = -1.5x[/tex]
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:
[tex]y = ax[/tex]
In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So
[tex]y = ax[/tex]
[tex]6 = -4a[/tex]
[tex]a = -frac{6}{4}[/tex]
[tex]a = -1.5[/tex]
So
The relation is [tex]y = -1.5x[/tex]
Write the standard form of each equation.
0=-x+y+3
Answer:
y = x - 3
Step-by-step explanation:
Linear equations are most often written in the form y = mx + b, where m is the slope of the line.
Here, 0=-x+y+3 can be re-written as x - 3 = y, or y = x - 3. Here the slope is 1 and the y-intercept is (0, -3).

Identify the volume of the pyramid.
21 in.
8 in.
7 in.
Answer
392in³
Step-by-step explanation:
Volume=base X height divided by 3 OR length X width X height divided by 3
length=8in
width=7in
height=21in
So, Volume = 8x7x21
1,176in³
Now divide by 392in³
Jeff Lytle can buy mulch for $2.39 a bag at the gas station. He can get six bags of the same mulch at the garden store for $15.00, or nine bags for $19.00. Which is the best buy?
nine bags for $19.00 is the best buy.
Answer:
Step-by-step explanation:
1 bag / $2.39 = $2.39
6 bags / $15.00 = $2.50 best buy is 9 bags
9 bags / $19.00 = $2.11
the perimeter of a triangle is represented by 3x² +8x-9. Two of its sides are represented by (x²+11x+5) and (-2x²-4x+2) What expression would represented the third side
Answer:
The third side has a length of 4x² + x - 16
Step-by-step explanation:
We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:
3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)
= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2
= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)
= 4x² + x - 16
