Misha solves the equation 3x-2(x+3)=4(x-2)-7by applying the distributive property to each side of the equation. The result is 3x

wlad13 [49]

Answer:

Option A

Step-by-step explanation:

we have

$3x-2(x+3)=4(x-2)-7$

Applying the distributive property to each side of the equation

$3x-2x-6=4x-8-7$

Combine like terms

$(3x-2x)-6=4x+(-8-7)$

$x-6=4x-15$

therefore

The terms that Misha should combine are 3x – 2x and –8 – 7

g What is the probability of being dealt exactly three of a kind (like three kings or three 7’s, etc.) in a five card hand from

Elena L [17]

Answer: 0.02257

Step-by-step explanation:

Given : Total cards in a deck = 52

Number of ways to select any 5 cards : $^{52}C_5$

Since , there are total 13 kinds of card (includes Numbers from 2 to 9 and Ace , king, queen and jack).

Of each kind , there are 4 cards.

Number of ways to select three cards in a five card hand of a single kind : $^{4}C_3\times^{48}C_2$

Number of ways to select three cards in a five card hand of a exactly three of a kind : $13\times^{4}C_3\times^{48}C_2$

Now , the required probability = $\dfrac{13\times^{4}C_3\times^{48}C_2}{^{52}C_5}$

$=\dfrac{13\times4\times\dfrac{48!}{2!46!}}{\dfrac{52!}{5!47!}}\\\\\\=\dfrac{58656}{2598960}$

$=0.022569027611\approx0.02257$

∴ The probability of being dealt exactly three of a kind (like three kings or three 7’s, etc.) in a five card hand from a deck of 52 cards= 0.02257

Each week, Arnold earns $92 for every shift he works at the theater and 13$ for every dog- walking job. He uses the expression 9

IRISSAK [1]

Answer:

Part A: Coefficients: 85 and 15

Variables: x = shifts at the theater, y = dog-walking jobs

Part B: 2 terms, the first one represents how much he earns working in the theater and the second how much he earns dog-walking. Each term is separated with a sum or a subtract sign.

Part C: 15y

Step-by-step explanation:

Part A: The variable of an expression is the information we don't know. In this case, we don't know how many shifts he has at the theater and how many dog-walking jobs he has. That's why we have 2 variables, x and y. The coefficient is the number that multiplies the variable. In this case, as we have 2 variables, we have 2 coefficients, 85 and 15.

Part B: In an expression, every term is separated with a sum or a subtract sign. In this case, we have just one sum, so the terms are the numbers and variables that appear before and after the sum sign. That's 85x and 15y. The first one is the amount of money he earns for every shift at the theater multiply by how many shifts he has, so that's how much he earns in total at the theater. The second one is the amount of money he earns for every dog-walking job multiply by how many he does, so that's how much he earns in total from the dog-walking jobs.

Part C: As I said in Part B, the second term is the total earned from the dog-walking jobs, so 15y represents it.
