Stan is $50 in his wallet and continues to save $6 each week from chores. Kyle has $34 in his wallet and continues to save $10 each week from chores. Write a linear equation for each person. Then solve it in the space below.

Answers

Answer:

Stan: y=6x+50

Kyle: y=10x+34

Step-by-step explanation:

The y-axis starts at 50 and increases by 6 for Stan's

The y-axis starts at 34 and increases by 10 for Kyle's

hope this helps
Stan: 6w + 50
Kyle: 10w + 34

The 50 and 34 are added in the equations because this is the amount that Stan and Kyle started out with. The w in the equations represents the number of weeks that Stan and Kyle save their different amounts of money.

how do u estimate decimal  like 11.6 and 0.25

Answers

Estimation is about rounding answers to the nearest whole or to a simple fraction.
11.6 is closer to 12 than it is to 11 so we can estimate that
11.6≈12

And .25 is closer to 0 than it is to .5 so we can estimate
.25≈0

It also depends what place we are rounding to, we can say that .25 is close to .3 because we don't want to have a 0 value
.25≈.3
If the number is 0-4 round it down to number that comes before.If the number is 5-9 round it up to the number that comes after.
