What is y+5x=6; x= -1,0,1

1 answer:

3 0

Y + 5x = 6

y + 5(-1) = 6
y + (-5) = 6
y - 5 = 6
y - 5 (+5) = 6 (+5)
y = 11
when x = - 1, y = 11

y + 5(0) = 6
y + 0 = 6
y + 0 (-0) = 6 (-0)
y = 6
when x = 0, y = 6

y + 5(1) = 6
y + 5 = 6
y + 5 (-5) = 6 (-5)
y = 1
when x = 1, y = 1

hope this helps

A sample of students is taken from the school’s A honor roll. The school estimates that there are actually 360 students on the A

zlopas [31]

Answer:

Number of 8th Graders = 360 - X

As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.

As we know:

Total number of students on the A honor roll = 360

We are asked to calculate, number of students from 8th grade on the A honor roll.

So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.

Mathematical Expression:

Number of 8th Graders = Total number of students on the A honor roll - X

Number of 8th Graders = 360 - X

So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

I am not sure if it is wrong I am sorrry.

Alan bought two bikes. He sold one to Beth for $300 taking a 25% loss. He also sold one to Greta for $300 making a 25% profit. D

Mashutka [201]

No Alan did not break even

Alan incured a loss of 6.25 %

Solution:

Given that,

Alan bought two bikes

He sold one to Beth for $300 taking a 25% loss

He also sold one to Greta for $300 making a 25% profit

When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss

Which is given as:

$loss\ \% = (\frac{x}{10})^2$

Here, x = 25

$loss\ \% = (\frac{25}{10})^2\\\\loss\ \% = 2.5^2\\\\loss\ \% = 6.25$

Thus the loss percentage is 6.25 %
