Answer:

z=-24

Step-by-step explanation:

(z-24)/8+2

(z-24)/10

((z-24)/10)10 Multiply both sides by 10

10(z-24) Distribute

10z-240 Divide both sides by 10

z=-24

Use order of operations... PEMDAS - the order you should attack all math problems.

Parentheses
exponents
multiplication
division
addition
subtraction

So you have to do the exponent THEN the multiplication

3*8^2 =
3 * 64 =

Answer:

x = 14

$h^2 = p^2 + b^2\\h^2 = 7^2 + 12^2\\x^2 = 49 + 144\\x^2 = 193\\so, x = 13.89\\so, x = 14$

In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. One dark morning you pull two socks from t

pishuonlain [190]

Answer:

D) 0.500

Step-by-step explanation:

Blue Socks = 6

Grey socks = 10

Probabilities to find :

Since there are a total of 16 socks, the probability of both socks being blue is

Probability(blue) = $(\frac{6}{16} ) \frac{5}{15} =\frac{30}{240} =\frac{1}{8}$

The probability of both being grey is

Probability(grey) = $(\frac{10}{16} ) \frac{9}{15} =\frac{90}{240} =\frac{3}{8}$

(Note: After 1 sock is picked , next sock drawn would have a different probability as 1 sock is already picked so it would be 1 minus the total socks available of that color)

The probability two socks match:

Probability(blue) + Probability(grey) = $\frac{1}{8}$ + $\frac{3}{8}$ = $\frac{4}{8}$ = $\frac{1}{2}$ = 0.500
