Each kit to build a castle contains 235 parts. How many parts are in 4 of the kits?

Answers

If one kit contains 235 parts, then all we need to do to find out how many are in 4 of those same kits is multiply the amount in one kit by the amount of kits there are.

235 * 4 = 940

There are 940 parts in 4 of the kits.
Hope that helped! =)
The answer to that is 940. Each part contains 235 parts and you need to know how many are in 4 kits, multiply 235 x 4 and you get the sum of 940.

Identity the property used in the first five steps to solve the equation 2(x-5)-6x=-22

Answers

2 ( x - 5 ) - 6 x = - 22

2 * x - 2 * 5 - 6 x  = -22

2 x - 10 - 6 x = -22

2 x - 6 x = - 22 + 10

- 4 x = - 12 * ( - 1 )

x = 12 / 4

x = 3

hope this helps!

PLEASE HELP YOU GUYS

Answers

Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .

Probability of both = (1/6) x (1/2) .
You do the multiplication.

4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .

Probability of both = (1/3) x (6/11) .
You do the multiplication.
