-10c+70, just distribute the the -10 to everything in the expression
Make a table graph and go from 0-10 top for weeks and bottom for miles, label one Jeramy and the other one tony. For Jeremy add one mile each week and for timely add to by week 4 they both should have ran 10 miles
Answer:
6.45
Step-by-step explanation:
Every part is 0.01 bigger or smaller
You can find it out by subtraction and then division
6.5 - 6.4 = 0.1
0.1 : 10 = 0.01
There are 10 parts that's why you divide it by 10.
If there will be 2 parts you will divide by 2
Answer:
Step-by-step explanation:
26% is (26-20)/(50-20) = 6/30 = 1/5 of the way between 20% and 50%. That means 1/5 of the solution is 50% acid.
50% acid: 1/5 · 100 mL = 20 mL
20% acid: 100 mL -20 mL = 80 mL
Delbert must mix 80 mL of 20% acid and 20 mL of 50% acid.
_____
Maybe you'd like to see an equation. Let x represent the amount of 50% acid required. Then 100-x is the amount of 20% acid needed. The amount of acid in the mix is ...
0.50(x) +0.20(100 -x) = 0.26(100)
(0.50 -0.20)x = (0.26 -0.20)100 . . . . subtract 0.20(100)
x = (0.26 -0.20)/(0.50 -0.20)×100 = 20
This last expression should look a lot like the one we started with in this answer. It shows you how you can almost write down the answer to mixture problems without a lot of work.
The ending balance after the transactions is; $59.25
<h3>How
to determine ending balance</h3>
To determine the ending balance after a number of transactions;
- Let money inflow and balance be represented as positive.
- Let money outflow be represented as negative.
Therefore; Since starting balance is; $822.67; we have;
- <em>$822.67 + $227.45 - $600.00 + $50 - $100 - $200 - $3.50 - $2.50 - $134.87.</em>
The ending balance on the account is therefore; $59.25
