Q: What is the least they could weigh together?
A: 0.62 kg
=================================================
Work Shown:
x = weight of first ball
y = weight of second ball
each ball has a weight range of 0.31 kg to 0.37 kg, so,

add straight down to get

which simplifies to

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.
--------
Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
-x+4y= -17
-x= -17-4y multiply everything by -1
x=17+4y
-6X-2y=2
-6(17+4y) - 2y=2
-102-24y-2y=2
-26y=2+102
-26y=104
y= -104/26
y= -4
x=17+4y
x=17+4•4
x=17+16
x=33
Answer:
The answer would be the second one is a function.
Step-by-step explanation:
Answer:
The square root of 8.3, and -8.3
Step-by-step explanation:
There is a 99.3 chance that neither occur cause you would add 0.3 and 0.4 together and get 0.7 then you would subtract 100 and 0.7 and get 99.3. So your answer is 99.3. Hope this helped :D
