Find the value of x need help

amm1812

Answer:

x=-10

Step-by-step explanation:

since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.

angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180

x+190=180

x=-10.

Which equation represents a proportional relationship?

Verizon [17]

y = 3 x equation represents a proportional relationship.

Answer: Option B

<u>Step-by-step explanation:</u>

A proportional variation represents a relationship between two variables x and y. It can be expressed in the form y=k x. Here, the ‘k’, the proportionality constant is equal to the slope m and the line goes through the origin

case A) $y=2\left(x+\frac{1}{3}\right)$

A linear equation that not passes through the origin and so not proportional variation

case B) y= 3 x

Is a linear equation but passes through the origin and so proportional variation

case C) y = - 3x+2

A linear equation that not passes through the origin and so not proportional variation

case D) $\text { D) } y=\frac{1}{2 x}$

An inverse variation equation but not passes through the origin and so not proportional variation.

From these, equation option B is the proportion equation because in these equations, there is no addition and subtraction of any constant number. That’s why both these equations become proportional equations.

Cruz has d $10-bills and 3 fewer $20-bills than he has $10-bills. Write an algebraic expression to represent how much money Cruz

murzikaleks [220]

So Cruz has d amount of 10$ bills.
The value of this money is 10d in dollars.

He has 3 fewer than d amount of 20$ bills.
So he has (d-3) of these 20$ bills.
The value of this money is 20(d-3) in dollars.

The total money that Cruz has is the sum of these values that we've already calculated:
10d + 20(d-3)

From there, you'll need to distribute the 20 to each term in the second set of brackets, and then combine like-terms to simplify.
