Help PleaseeeeGiven The Triangle Below, What Equation Would You Use To Solve For X? Use Your Equation

Answers

Answer 1

Answer:

x=15

Step-by-step explanation:

so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180

subtract 90 from both sides: 6x=90

divide by 6: x=90/6

simplify: x=15

c. y=23x
d. y=115x

Answers

Answer:

Step-by-step explanation:

Answer:c.y=23x

because A student spends the same amount each week for bus fare => in each week, he spents:  115 : 5 = 23 ($)

with x = the number of weeks, the equation shows this relationship is y = 23x

Help please?????? Mean and Median

Answers

Answer:

Mean: 10

Median: 11

Step-by-step explanation:

To find the mean you have to add up all the numbers then divide by how many there are.

E.g in 1,2,3,4 there are four numbers there so you add them all up and divide by 4

To find the median you have to sort out the numbers and put them in order of smallest to largest. Then you find the middle number.

E.g 2,3,1,4,5

You put them in order: 1,2,3,4,5

Then find the middle which is 3.

I hope you found this useful.

Answer: Mean is 9.111 and the Median is 5 I think.

Step-by-step explanation:

Mean= Add all numbers up then divide by how many numbers

Median= Numeric order, then count how many numbers, and then divide by 2 if its odd round up to nearest ones digit.

The equation of line is given by y = ( 4/3 )x + 7/3 , where the slope of the line is m = 4/3

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

3y - 4x = 7   be equation (1)

On simplifying the equation , we get

Adding 4x on both sides of the equation , we get

3y = 4x + 7

Divide by 3 on both sides of the equation , we get

y = ( 4/3 )x + 7/3

Now , it is expressed as y = mx + b where m is the slope and b is the y-intercept

Hence , the equation of line is y = ( 4/3 )x + 7/3
