Answer:
Step-by-step explanation:
Let's get some organization going here and number the equations:
1. A+B=25.6
2. A+C=41.6
3. B+D=25.6 and
4. C-D=19.2
First I am going to solve equation 1 to get new equation 5:
5. B=25.6-A (hold that for a sec) and then solve equation 2 to get new equation 6:
6. C=41.6-A
Now sub equation 5 into equation 3:
25.6-A+D=25.6 and
A-D=0 so
A=D. That's good. Now we move on:
Sub equation 6 into equation 4 to get
41.6-A-D=19.2. But since A = D:
41.6-D-D=19.2 so
41.6-2D=19.2 and
-2D=-22.4 so
D = 11.2 and so does A.
Now we will fill in to get B and C.
In equation 2, with A = 11.2:
11.2+C=41.6 so
C = 30.4.
For B, use the fact that D = 11.2 in equation 3:
B+11.2=25.6 so
B = 14.4
All in all:
A = 11.2
B = 14.4
C = 30.4
D = 11.2
Yikes!!
The answer is $1242.24
good luck
Answer:
6.05, 6.10, 6.50 6.9
Step-by-step explanation:
Since each digit in the ones place are the same and the tenths place are different, look at the tenths place. If the digit in the tenth is larger than the rest, then it is greater than all numbers.
You would do the exact same steps for each place number (tenths, hundredths, ones, tens, etc.)
