X+x+1=-29
x+x=-29-1
2x=-28
2x/2=-28/2
x=-14
Answer x=-14, x+1=-15
X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
Answer:
126 apples
Step-by-step explanation:
Let the number of apples picked by Mary=m
Cindy picks 6 times as many as Mary= 6Xm=6m
John picks 8 times as many as Mary= 8Xm=8m
Altogether they picked a total of 135 apples.
m+6m+8m=135
15m=135
m=135/15
m=9
We want to determine how many apples John and Cindy Picked.
John Picked 6m apples
Cindy Picked 8m apples
Their combined total= 6m+8m =14m
Since m=9
14m =14 X9 =126 apples
John and Cindy picked a total of 126 apples
The radical parts are gonna be easiest. You plug the radicals into your calculator and get a decimal. Next, you determine which decimal is greater. For turning fractions into decimals, change the fractions into improper fractions and divide the numerator by the denominator (the top number and the bottom number). You'll get a fraction then compare.
For the graphing area, you do the same thing, turn everything into decimals and place them on the graph.
Good luck!
