D is the property used in solving that equation
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:
1/2
Step-by-step explanation:
The formula for the slope given two points is
m = (y2-y1)/(x2-x1)
= (1--2)/(8-2)
= (1+2)/(8-2)
=3/6
1/2
Hey there!
Given rule is 2x-8
Given x = 8
On substituting ,
=> 2(8)-8
=> 16-8
=> 8
8 is the answer mate!
Hope it helps you
