How is the answer 35? How do I get it?

vlabodo [156]

I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.

Triangle m is similar to triangle n. Triangle m has two angles with measures of 32°and 93°. Which two angles measures could be i

inysia [295]

Given that triangle m and n are similar, then the implication is the ratio of the corresponding sides are the same and the corresponding angles are equal. This implies that if the two angles of triangle m measure 32° and 93°, then the possible size for the two angles in triangle n will be 32° and 93°.

Determine whether this situation represents independent or dependent events. "Three green jelly bean, five red jelly beans and t

igor_vitrenko [27]

Answer:

Independent Events

Step-by-step explanation:

Given

$Green = 3\\ Orange = 2\\ Red = 5$

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

<u>Before selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

<u>After selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

Which pairs of variables have a linear relationship? Select

Neko [114]

Answer:

Side length and perimeter of 1 face

Area of 1 face and surface area

Step-by-step explanation:

Suppose you are given cube with side length of x units.

Then

Side length = x units

Perimeter = 4x units

Area of 1 face $=x^2$ square units

Surface area $=6x^2$ square units

Volume $=x^3$ cubic units

A linear relationship is any equation that, when graphed, gives you a straight line.

Consider all options:

A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function $y=kx$ is a straight line.

B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation $y=kx^2$ .

C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation $y=kx^{\frac{3}{2}}$ .

D. Area of 1 face and surface area is a linear relationship, because the graph of the function $y=kx$ is a straight line.

E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation $y=kx^3$ .
