An equation and the steps to solve it are shown below:2x − one over four (12x + 4) = 3 Step 1: 2x + 3x + 1 = 3 Step 2: 5x + 1 = 3 Step 3: 5x + 1 − 1 = 3 − 1 Step 4: 5x = 2 In which step was the error made and why? Step 1, because incorrect signs have been used Step 2, because the terms have been added incorrectly Step 3, because a number has been subtracted from both sides of the equation No error was made

Answers

3 x 3 3/4 =

3 x 15/4 = 45/4 = 11 1/4 milliliters
She would use 11 and 1/4 milliliters to make the perfume. 3+3+3=9. 3/4+3/4+3/4= 2 and 1/4. 9+2 and 1/4= 11 and 1/4 milliliters:) 

Tom,Scott and dawn sold cookies at the school fair.Tom had 90 cookies and sold 60% of them.
Scott had 150 cookies and sold 2/3 of them.
Dawn sold 46 cookies.
What percentage of the cookies sold were sold by Dawn?

Answers

first of all work out how many tom and scott sold.
tom sold 60% of 90 cookies which is 54.
scott sold 2/3 of 150 cookies which is 100.
altogether the three of them sold 54+100+46 cookies which is 200.
Dawn sold 46 of these 200 cookies. To work out the percentage we have both the numbers to get 23 out of 100. We halved those numbers because a percentage is out of 100 we halved it to get it out of 100.
so 23 out of 100 is 23% so dawn sold 23%of the cookies.

Hope this helps :)

Imagine each letter of the word “Mathematical” is written on individual pieces of paper and placed in a bag. Should you pick a random letter from that bag, what is the probability that you pick a vowel?

Answers

Answer:

The probability to pick a vowel is   (5)/(12) }

Step-by-step explanation:

Probability = Required outcome / All possible outcome

From the question;

the word “Mathematical” is written on individual pieces of paper

We have to count the total numbers of letter present in the word

When we count properly, we have 12 total numbers of letters

The we proceed to count the numbers of vowel

Here are the vowel in the word  “Mathematical” :

a, e, a, i, a

The vowels are 5 letters

Probability = Required outcome / All possible outcome

Required outcome = 5

All possible outcome = 12

Probability =  (5)/(12) }

The probability that you pick a vowel  is  (5)/(12) }

In the word "Mathematical"

Vowels are "a", "e", "a", "i", "a" from left to right

Consonants are "m", "t", "h", "m", "t", "c", "l"

5 vowels and 7 consonants of total 12 letters

So the probability of picking a vowel is

(5)/(12)
