1.8. One way to figure this out is to divide 3 by 5 (the denominator) which is equal to 0.6, then multiplying that by 3 (the numerator) which would be 1.8.

Which describes the first step in solving the equation 4x - 7 = -15?
GalinKa [24]

Answer:

Add 7 to both sides

Step-by-step explanation:

You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.

Then you would get 4x = -8.

Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.

x = -2

Which event has a probability other than 1/2?
Vadim26 [7]

Answer:

Option B.

Step-by-step explanation:

In the given events lets find out the event that has a probability other than 1/2.

A. Flipping a coin gives result of head or tail, so the probability of the result of tails is 1/2.

B. Choosing a vowel from a bag of tiles that contains one of each letter of the alphabet, so the probability of choosing vowel is 5/26.

C. A cube that has numbered from 1 to 6, there are 3 even numbers and 3 odd numbers, so the probability of rolling even number is 3/6 or 1/2.

D. There is 26 red cards in a standard deck of 52 cards, so the probability of choosing red card is 26/52 or 1/2.

Therefore, events A, C and D gives result of 1/2 and B other than 1/2

So Option B is the correct answer.
