Because you would multiply 5 by 4 NOt add them
Answer:
895/53 or 16.887 (rounded)
Step-by-step explanation:
3 + 2 * 7 - 60 / 530
(2x7=14) (-60/530= -6/53)
3 + 14 - 6/53
(3 + 14=17)
17 - 6/53
=895/53 or 16.887 (rounded)
You are finding the area because 6x3=18 if it is a quadrilateral.
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
