Answer:

Step-by-step explanation:
3x-2y=24......eqi
x+2y=48........eqii
now solving eq i&ii
4x=72
x=72/4
x=18
now putting the value of x in eqii
18+2y=48
2y=48-18
y=30/2
y=15
Let p = the number of pennies
let q = the number of quarters
p + q = 23
0.01p + 0.25q = 3.11
0.0000009
.9 times 10 is 9, so then you have to move it back -6 times behind the decimal.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
If the figure ABCD and the figure RSPQ are congruent
then
The corresponding sides and corresponding angles are equal
so








Hi there!
The correct answer is 6.25 times.
This is how you get there:
1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm
2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25
If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.
I hope that I have been able to simplify this problem for you!
