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

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100

Answers

Answer:

yes

Step-by-step explanation:

to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-

81*2/9=18

900*2/9=200

72*2/9=16

450*2/9=100

now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

good luck :)

Step-by-step explanation:

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?

Answers

Answer:

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

Step-by-step explanation:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.

Answer:

a. $450

b. $135

c. 70%

Step-by-step:

[tex]\frac{70}{100} = \frac{315}{450}[/tex] since these two fractions are equal to each other that means the orginal price is $450.

(sale price/original price)x100= % of original price

(315/450)x100=0.7=70%

(-2,3) is one vertex of a square on a coordinate plane. Name three points that could be the other vertices.

Answers

Answer:

(0,7) and (-4,7)

(-2,3) is vertex

Equation is (X+2)2+3

When x = 0, y = 7 and when x = -4, y = 7

(-2,3) is one vertex of a square on a coordinate plane. (0,7) and (-4,7) could be the other vertices.

How can we perceive the cartesian coordinate plane?

The cartesian coordinate plane is an infinite 2-dimensional plane. Any 2-dimensional figure can be drawn on an infinite 2d plane.

Each point of a cartesian plane is tracked by a location.

It is the perpendicular distance of that point from the horizontal axis and vertical axis usually named the x-axis and y-axis.

The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called the x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis and called the y-coordinate of that point.

(-2,3) is one vertex of a square on a coordinate plane.

The equation is [tex](X+2)^2+3[/tex]

When x = 0,

[tex](0+2)^2+3\\\\4+3[/tex]

y = 7

when x = -4,

[tex](-4+2)^2+3\\\\4+3[/tex]

y = 7
