Let X = number
2X = X/4 + 14
multiply both sides by 4
8X = X + 56
subtract X from both sides
7X = 56
divide both sides by 7
X = 8
Check: 8*2 = 16. 8/4 = 2. 16 is fourteen more than 2. Checking your work ensures that you used the appropriate equation for the problem, as well as catching any errors in arithmetic.
4: whose double is 8 and quarter is 1. If the missing number is x, then: 2x = x/4 + 7 Multiply throughout by 4: 8x = x + 28 Subtract x from both sides: 7x = 28 Divide throughout by 7: x = 4
A quarter of 180 is 45. To find a quarter of a number, you divide the number by 4. In this case, 180 divided by 4 equals 45. So, a quarter of 180 is 45.
Well, isn't that a happy little math problem! To find a quarter of 26, you can simply divide 26 by 4. When you do that, you'll find that a quarter of 26 is 6.5. Just imagine that quarter sitting there, all peaceful and content.
60
50. First you have to find out what a quarter of 400 is before you can take half of that number. So one quarter of 400 is the same as dividing by 4, so the answer is 100. Then you'll need to take half of that number, which is 50.
-4
fourteen less than three fourths of a number is negative eight find the number
A quarter of 400 pounds is 100 pounds. To find a quarter of a number, you divide the number by 4.
4: whose double is 8 and quarter is 1. If the missing number is x, then: 2x = x/4 + 7 Multiply throughout by 4: 8x = x + 28 Subtract x from both sides: 7x = 28 Divide throughout by 7: x = 4
You multiply the number by .25 or divide the number by 4, they will both give the correct answer.
A quarter of 180 is 45. To find a quarter of a number, you divide the number by 4. In this case, 180 divided by 4 equals 45. So, a quarter of 180 is 45.
There are fourteen multiples of seven that are under 100.
double it
50. First you have to find out what a quarter of 400 is before you can take half of that number. So one quarter of 400 is the same as dividing by 4, so the answer is 100. Then you'll need to take half of that number, which is 50.
A quarter is huge compared to an atom. To put them in perspective let's calculate how many atoms are in a US quarter: -The current US quarter has a mass of 5.67g and is 8.33% nickel and 91.67% copper. -From the mass and percentages of each element we can find that there are 5.20g of copper and 0.472g of nickel in each quarter. -Dividing the mass of each element by its molar mass we find that there are 0.0818 moles of copper and 0.00805 moles of nickel in each quarter. -Multiplying the number of moles of each element by Avogadro's number we find that there are 4.93x1022 atoms of copper and 4.85x1021 atoms of nickel in each quarter. This means there is a total of 5.41x1022 atoms in a US quarter. Let's write that number out to get a little more perspective: 54,100,000,000,000,000,000,000 That certainly is a huge number!
Simply reverse the conditions. Add 14 to 154, which is 168 and then half it, which is 84.
Three quarters of a number less one quarter of a number = two quartres, or a half of the number. A half of 76 = 76/2 = 38
