Answer:
x+ 8
Step-by-step explanation:
X squared+y=18
x+y=6. use elimination method.(+y and +y cancels
x squared -x=x
18-6=12
x=12
for y take one of the above equations
x+y=6(replace x with 12
12+y=6(collect the like terms
y=6-12
y=-6
so x=12 and y=-6
In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:
Let x = be the total length
X = 4(112)
X = 448
Therefore,
34m + 1m + 212m = 247m
448m - 247m = 201 length of the fourth jump rope
A number that stands out and isn't close to any other number
