Simplify 5x - 3(x – 2) – x

Answers

Answer:

x - 2

Step-by-step explanation:

distributive property first since you stick with parentheses first (PEMDAS)

so 3x - 6 is what it would be.. then you would want to think of the equation as 5x - 3x - 2 - x. seems somewhat complicated but to others not so much.

Next you’re gonna just want to subtract, but you should probably make the problem easier so you can just subtract across right? it’d be 5x - 3x - x - 2. that way all the x variables are together and anything else is separate.

5x - 3x is 2x - x or - 1x is x or 1x.

i think just using the variable x for it being 1 is easier so now we have the problem x - 2.

anything else? nope! that’s the simplified equation.

hope that i was able to help :)

3x = 165

x = 55

Answer: B. 55

Step-by-step explanation:

You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.

---------------------------------------------------------------------------------------

Given

(2x+15)+x=180

Expand parenthesis

2x+15+x=180

Combine like terms

3x+15=180

Subtract 15 on both sides

3x+15-15=180-15

3x=165

Divide 3 on both sides

3x/3=165/3

x=55

Match the term with the definition.
Triangle A) perpendicular cross section of a cylinder
Rectangle B) shape created when a right triangle is rotated about the y-axis
Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid

Answers

Answer:

Step-by-step explanation:

Perpendicular cross section of a pyramid -------   triangle.  

Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.

Perpendicular cross section of a cylinder -------  rectangle

diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)

parallel cross section of a sphere ------ circle

when you cut sphere a side would appear with shape of circle.

shape create....    -----    cylinder.  

one side of rectangle would be high of cylinder and other would be radius of it.

last one is cone.  If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.

Which statement correctly describes the relationship between the lengths of the sides of the triangle shown below?
