Assuming she set up the problem vertically, she began subtracting from the left, instead if the right.
Step-by-step explanation:
this is my answer...sorry if I made any mistake
There is not enough information to give a numerical answer.
Let t=number of ten dollar bills.
"he has twice as many dimes as he has 10 dollar bills", so the amount A is
A=10*t+0.1*(2t)
"he has twice as many pennies as he has dimes"
A=10*t+0.1*(2t)+0.01*4t
"chris has twice as many 1 dollar bills as pennies"
A=10*(t)+0.1*(2t)+0.01*(4t)+1*(8t)
=18.24t
Therefore the total amount Chris has is 18.24 times the number of $10 bills he possesses.
<span>Let x be the speed of the first car, then (x + 10) is the speed of the second car.
We can write the equation by the condition of the problem:
</span>
mph s<span>peed of the first car
</span>
Then 30+10=40 mph speed of the second car
Answer: 30mph and 40 mph.

Answer:
2
Step-by-step explanation:
If you use rise over run, you should get to. From one point to the other, the rise is 2 and the run to the right is 1. So, you do 2 divided by 1, which is 2. So, the slope would be 2.
