On Monday, 412 students went on a trip to the zoo. All 8 buses were filled and 4
students had to travel in cars. How many students were in each bus?
Let s = number of students on each bus?
Answer:
51
Step-by-step explanation:
Let x be the number of people in a bus. Since we have the total and the people in the car in addition to the number of busses, we can write an equation like this:
total students = (number of people in a bus) * (number of busses) + leftovers
Our equation we come up with is:
412 = s * 8 + 4
Solve
s*8=408
s=51

Answer:
A = 97.5
Step-by-step explanation:
Since A & B are supplementary, the general equation would be:
180 - 82.5 = A
A = 97.5
1) 2x – 3y - z = 7
3x + 5y - 3z = -2
4x – y + 2z = 17
When this system of equations is solved, what is the value of x?
Answer:
x = 3
Step-by-step explanation:
2x - 3y - z = 7 (equation 1)
3x + 5y - 3z = -2 (equation 2)
4x – y + 2z = 17 (equation 3)
(1) * 3 : 6x - 9y - 3z = 21 (1)'
(1)' - (2) : 3x - 14 y = 23 (equation 4)
(1) * 2 : 4x - 6y - 2z = 14 (1)"
(1)" + (3) : 8x - 7y = 31 (equation 5)
(5)*2 : 16x - 14y = 62 (5)'
(5)' - (4) : 13x = 39
x = 3
So thus, x = 3 in this system of equations, you can plug x back into equation 4 or 5 to find y and then plug x and y back into equations 1, 2, or 3 to find z

Help me out please!!!!!!
Step-by-step explanation:
y = 2x + 9
y = -x - 3
there are multiple ways to solve this.
let's follow the approach that both x-expressions must be equal :
2x +9 = -x - 3
3x = -12
x = -4
y = -x - 3 = 4 - 3 = 1

given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=920(1.05)^x
Answer:
Growth
Step-by-step explanation:
since the (1.05) is bigger than 1 it is growth but if it was lower then 1 it would be decay .
The exponential function represents the growth and the percentage rate of increase is 5%
What is an exponential function?The formula for an exponential function is f (x) = aˣ, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Given exponential function y = 920(1.05)ˣ
since the base value of the function is greater than 1 then the function shows growth.
for the rate of increase,
let x = 0 for the initial value
y = 920(1.05)ˣ = 920(1.05)⁰ (a⁰ = 1)
y₀ = 920
now x =1
y = 920(1.05)ˣ = 920(1.05)¹
y₁ = 966
percent increase = 100(y₁ - y₀)/y₀
percent increase = 100(966 - 920)/920
percent increase = 100 x 0.05 = 5%
Hence the growth of function at the rate of 5%.

This is for the real ones- find the missing side x. Giving brainliest.
Answer: The answer is X equals 10 2/3.
Explanation: This is a proportion. We see that the right rectangle when turned to the right is proportional to the left rectangle. On the left rectangle, the smaller side is 6 ft, and the larger side is 16 ft. On the right rectangle, the smaller side is 4 ft. 6 ÷ 1.5 = 4, therefore 16 ÷ 1.5 = 10 2/3.

6. zero
7. -4/5
8. 1
9. 0
10. 3/4
11. undefined
12. -9/4
The required slope for the lines is given below.
Given that,
Pot of line and points on the lines are given, we have to determine the slopes of the lines.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (-1, -11), (-6, -7)
m = -7 + 11 / -6 + 1
m = -4/5
Similarly,
Slopes of the line can be calculated as
1.) 4/2 2.) -3/5 3.) 2/2
4.) not defined because the denominator becomes zero or perpendicular to x-axis.
5.) -5/1
6.) zero because the line is parallel to the x-axis
7.) -4/5 8.) 1 9.) 0 10.) 3/4
11.) not defined because the denominator becomes zero or perpendicular to the x-axis.
12.) -9/4

The discount percentage is 20%.
Given that the competitor is selling an item for $ 150.00, while the price for that item in the store is $ 120.00, the following calculation must be performed to determine the discount percentage:
150 = 100 120 = X 120 x 100/150 = X 80 = X 100 - 80 = X 20 = X

Answer:
[tex]\boxed{\sf x=2}[/tex]Step-by-step explanation:
[tex]\sf 19 =5+7x[/tex]
First, let's swap sides so that all variable terms are on the left hand side.
[tex]\sf 5+7x=19[/tex]
Subtract 5 from both sides:
[tex]\sf 7x=19-5[/tex]
Subtract 5 from 19:
[tex]\sf 7x=14[/tex]
Divide both sides by 7:
[tex]\sf \cfrac{7x}{7} =\cfrac{14}{7}[/tex]
[tex]\sf x=2[/tex]
