Answer: £5000
Step-by-step explanation:
If 12% decrease = £600
Then (100- 12)% = x
100% = x
0.12x = 600 x 0.88
0.12x = 528
Divide both sides by 0.12
£4400
Therefore, original price before 12% decrease was £5000
The smallest of the four numbers is x.
Since the four numbers are consecutive, this means that each number is one more than the previous.
Therefore, the four numbers are:
x
x + 1
x+1 + 1 = x+2
x+2 + 1 = x+3
Now, we are given that the sum (s) of the four numbers is 2174
This means that:
s = x+x+1+x+2+x+3
s = 4x + 6
We are given that s = 2174. Substitute with s in the above equation and solve for x as follows:
2174 = 4x + 6
4x = 2174 - 6
4x = 2168
x = 2168 / 4
x = 542
Based on the above calculations, the four numbers are:
542, 543, 544 and 555
Hi!
We will solve this using proportions, like this:
88 miles in 3 hours
x miles in 4 hours
________________
x = (88*4)/3
x = 352/3
x = 117,33 miles in 4 hours
Hope this helps!
Answer:
2:1 or 2
Step-by-step explanation:
<em>*** </em>(Ratios can be written as " a : b", or can be written as a fraction " a / b".
>> therefore 10/5 can be simplified to 2/1 )<em>***</em>
For every 10 notebooks, there are 5 ballpens.
Therefore, for every 2 notebooks there is 1 ballpen (The simplification).
<u><em>EXTRA: </em></u>
**Also remember that the ratio of notebooks to ballpens cannot be reversed into ballpen to notebook ratio, because this would change the meaning.
2/1 is not the same as 1/2 **
