3 x 2 + 2x -5 = x or 1x. or 3x 2 + 2x - 5 = 5x + 3.
-4 + 7x 2 = -2 + 7x
Answer:
whats the question
Step-by-step explanation:
Answer:
Total money Betsy spent on T-shirt = £ 16.5
Total money Betsy spent on Bag = £ 28.5
Step-by-step explanation:
As given, Total money Betsy have = £ 75
Given that Betsy saved 40% of £ 75
⇒Betsy saved = £ 30
So, total money spent on T-shirt and bag = £ 75 - £ 30 = £ 45
Let Betsy spent money on T-shirt = x
Betsy spent money on Bag = y
⇒ x + y = £ 45 ........(1)
As given, She spent £12 more on the bag than she spent on the T-shirt.
⇒ y = £ 12 + x
Put the value of y in equation (1), we get
x + £ 12 + x = £ 45
⇒ 2x + £ 12= £ 45
⇒ 2x = £ 45 - £ 12
⇒ 2x = £ 33
⇒ x = £ = £ 16.5
⇒ x = £ 16.5
⇒ y = £ 12 + £ 16.5 = £ 28.5
∴ we get
Total money Betsy spent on T-shirt = x = £ 16.5
Total money Betsy spent on Bag = y = £ 28.5
Answer:
2/5
Step-by-step explanation:
25% is equal to 1/4
Lets think of this as money
If we take .25 and multiply it by 4 we get 100 or 1.00
Lets take 5/20
5/20 is also equal to 25%
For this one, let's change the fraction to an equivalent fraction. To do this I'm going to multiply both the top and bottom by 5.
5*5/20*5
That gets us 25/100
Back to thinking money-- we know that 25/100 is equal to 25%
25/100
We just determined that 25/100 is 25% using the problem above.
-----------------------------------------------------------------------------------------------------------------
The odd one out-- 2/5
2/5 is equal to 40%
If we think of this fraction as money and we get an equivalent fraction-- 40/100
We can clearly see that that is not 25/100, 1/4, 5/20, or even 25%
Hence making it not equivalent to 25%
