and 2 blue shoes. If he randomly chooses a pair of pants and shoes, what is the probability that both are black? Give your answer as an exact fraction and reduce the fraction as much as possible.

Answer:

Probability of choosing a black pair of pants and shoes = \frac{6}{91}

Step-by-step explanation:

Given:

Total number of pants Mike has =\textrm{ 3 tan pants + 5 jeans + 2 black pants + 3 gray pants = 13 pair of pants}

Probability of randomly choosing a pair of black pants = \frac{\textrm{Number of Black pants}}{\textrm{Total number of pants}} = \frac{2}{13}

Total number of shoes Mike has = \textrm{ 2 brown shoes + 3 black shoes + 2 blue shoes = 7 pairs of shoes}

Probability of randomly choosing a pair of black shoes = \frac{\textrm{Number of Black shoes}}{\textrm{Total number of shoes}} = \frac{3}{7}

Probability of choosing a black pair of pants and shoes =  \frac{2}{13}\times \frac{3}{7} = \frac{6}{91}

Is x+3=-5y in standard form?
skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is Ax+By=C with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

x+3=-5y

Subtract 3 from both sides.

x=-5y-3

Add 5y.

x+5y=-3

What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) 7x2 + 5x 7x2 + 11x 11x2 + 5x 11x2 + 11x
Anuta_ua [19.1K]

we have

(9x^{2}+8x)-(2x^{2}+3x)

Step 1

Eliminate the parenthesis

(9x^{2}+8x)-(2x^{2}+3x)=9x^{2}+8x-2x^{2}-3x

Step 2

Group terms that contain the same variable

9x^{2}-2x^{2}+8x-3x

Step 3

Combine like terms

7x^{2}+5x

therefore

the answer is

7x^{2}+5x
