Answer:
Grace jumped for 9 minutes and Zoe jumped for 12 minutes
Step-by-step explanation:
Let Grace jumped for x minutes and Zoe jumped for y minutes
Grace jump no. of times in 1 minute = 66
Grace jump no. of times in x minutes = 66x
Zoe jump no. of times in 1 minute = 56
Zoe jump no. of times in x minutes = 56x
We are given that Their jumps today and together they jump 1266 times in the total of 21 minutes
So, x+y=21 ----1
66x+56y=1266 ---2
Substitute the value of x from 1 in 2
66(21-y)+56y=1266
y=12
x+y=21
x+12=21
x=21-12
x=9
Hence Grace jumped for 9 minutes and Zoe jumped for 12 minutes
Answer:
The answer to the question is 16
Step-by-step explanation:
To find out the answer all we need to do is:-
Do addition for the first set of 20's. ( Or Multiply The 20's)
20 + 20 + 20 + 20 + 20 (or) Number of 20's = 5
= 40 + 40 + 20 The number = 20
= 80 + 20 Therefore, 20 × 5 = 100
= 100
-----------------------------------------------------------------------------------------------------------
Number of tens = 2 Therefore, 10 × 2 = 20
The number = 10
Now, we subtract 100 - 20 = 80.
-----------------------------------------------------------------------------------------------------------
We have 80 and now we divide the number by 5
If we do that we get the answer as 16.
I hope this answer helps.
