Step-by-step Answer:

There is a total of 10 coins, 5 dimes, 2 quarters and three pennies.

By picking a coin, it could be any that shows up out of the 10, so the probability of picking any coin in particular is 1 / 10.

If there are 5 dimes, the probability of picking ANY one particular dime is 1/10, so with 5, the probability of picking ANY of the five dimes is 5/10 = 1/2.

Going along the same line of thought, the probability of picking any of quarters and pennies would be 2/10+3/10 = 5/10 = 1/2 as well.

-1 (1 + 7x) - 6(-7 -x) = 36

S_A_V [24]

Answer: x = 5

Step-by-step explanation:

If you need to solve for x,

Given:

-1 (1 + 7x) - 6(-7 -x) = 36

Distribute:

-1 - 7x + 42 + 6x = 36

Combine like terms:

- x + 41 = 36

Subtract 41 from both sides of the equation:

- x = -5

Divide both sides by -1:

x = 5

Consider the equation ax+3/2=6

Rufina [12.5K]

1) C and 2)D
ax+3/2=6
ax=6-3/2
ax=9/2
multiple both sides by 1/a
x=9/2a
then plug in 2 for a
x=9/(2•2)
x=9/4
