Andy is not correct because when adding the 2 fractions, he needs to create fractional parts with the same denominator. NOTHING can be added unless the units are the same. The denominator of a fraction are the units. He needed to make 3/5 = 12/20 and 1/4 = 5/20. Adding these together would be 17/20, making 3/20 of them NOT action or comedy. 17/20 + 3/20 = 20/20 or the total.
Answer:
Step-by-step explanation:
Let x be the number of quaters and y be the number of dimes Roberta has.
1. Quater is equal to 25 cents, then x quaters is equal to 25x cents. Dime is equal to 10 cents, then y dimes is equal to 10y cents. $4.00=400 cents, then
25x+10y=400.
2. Roberta has 5 more dimes than quarters, then
y=x+5.
3. The system of equations is
Substitute second equation into the first one:
10 quaters and 15 dimes
Answer:
(2,-2)
Step-by-step explanation:
since the solution area is the shaded and dotted area, just plot the coordinates listed and see if they land in that space. by doing that, your answer should be the only one in that area: (2,-2)
Answer:
the slope is -3/4
Step-by-step explanation:
this is because you need to do rise/run not run/rise, you set it up as a table
<u>x l y</u> Then, you would just find the difference between the two x coordinates and the two y coordinates, and find whether they increase or decrease
-3,5 you can see that from -3 to postive 1 there
1,2 is an increase of 4. you can also see that from 5 to 2 there is a decrease of 3. The y and x point have to flop places to become rise/run and it shows that the slope is -3/4 :) i hope this helps
