Firstly, add 7 on both sides of the equation:
Next, before you can subtract 3/4x on both sides, you first have to find the LCD, or lowest common denominator, of 2 and 4. To find it, you would list the multiples of both and the lowest multiple they share is their LCD. In this case, the LCD is 4. Multiply 5/2 by 2/2 and 3/4 by 1/1:
Now subtract 3/4x on both sides of the equation:
Lastly, multiply both sides by 4/7 and <u>your answer will be x = 12.</u>
Answer:
1 in 41,539,806.
Step-by-step explanation:
The number of ways to pick 5 numbers from 45 = 45C5
= (45*44*43*42*41) / (5*4*3*2*1)
= 1,221,759.
There are 34 ways to pick a gold ball so total number of ways to get 6 matching numbers is
1221759*34
= 41,539,806.
The answer to your problem is 10 oz
The employee discount is 30% off. Here's the process to find this answer:
Calculate the difference between the original price and the discounted price. We're trying to find the percentage of the discount, not the percentage 38.50 is of 55.
55 - 38.5 = 16.5
Multiply the difference by 100 as part of the percentage formula. (is over of is equal to the percentage over one hundred)
16.5 * 100 = 1,650
Divide your result by 55 as the final part of the percentage formula.
1,650 / 55 = 30
Answer: B = 64
Step-by-step explanation:
To find B, we need to perform reverse operations. First, add 1 back to 15, which gives us 16. 16*4=64, which means that B must be equal to 64.
