Describe the angle relationship and solve for the x.

​

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

answer is (0,4) which means

it is in the middle of the

1st and 4th quadrant.

Step-by-step explanation:

did in class :)

The graph of the line given by the equation will pass through (0, -4) and (16/3, 0) and go from 3rd quadrant to first quadrant.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Equation of a line slope intercept form is y = mx + c.

m : slope

c : intercept along y axis, this is the y coordinate of the point when x coordinate equals zero.

The given equation is y = 3/4 x - 4.

The line has a positive slope.

So as x increases, y also increases, so the graph will be in the positive direction.

Graph will go from quadrant ||| to quadrant |.

Graph touches the Y axis at the point (0, -4).

Graph touches the X axis at point (16/3, 0).

Hence the graph will pass through (0, -4) and (16/3, 0) and go from quadrant 3 to quadrant 1.

Answer:   25 cartons

========================================================

Explanation:

1 liter = 1000 mL

Note how 1000/200 = 5, which means that if one carton is 200 mL, then five cartons gets us 5*200 = 1000 mL = 1 liter. If it takes five cartons to get 1 liter, then we'll need five times as many cartons to get to 5 liters. So 5*5 = 25 cartons is our goal.

---------

We could also solve like this

(1 carton)/(200 mL) = (x cartons)/(5000 mL)

1/200 = x/5000

1*5000 = 200x .... cross multiply

5000 = 200x

200x = 5000

x = 5000/200 ..... divide both sides by 200

x = 25

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( x ) = 3x - 7

Now , substituting the value of f ( x ) = 20 , we get

when x = c

f ( c ) = 3c - 7

The value of the equation f ( c ) = 20

Substituting the value in the equation , we get

3c - 7 = 20

On simplifying the equation , we get

Adding 7 on both sides of the equation , we get

3c = 27

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

c = 9

Therefore , the value of the variable c = 9

Hence , The value of c so that the function f ( c ) = 20 is when c = 9
