A)
Note that there are only two numbers that correspond complete wording of question: 59 and 68
It is easy to verify that the number found number is 68:
Look:
6 + 8 = 14 and
<span>86 - 68 = 18
b)
Now you can solve one system:
x + y = 21
x - y = 5
Add both equations:
2x = 26
x = 13
So: y = 8

Answer:
x ≤3
Step-by-step explanation:
4x+6 ≤ 18
Subtract 6 from each side
4x+6-6 ≤ 18-6
4x ≤12
Divide each side by 4
4x/4 ≤12/4
x ≤3
Answer:
this whole sentence confused me a lot
Step-by-step explanation:
yes there is, but it depends on how you want to do it
Both of your answers are correct!
so yes youre doing it right
0.28 is the same thing as 28/100.
We can divide 4 to the top and the bottom.
28 / 4 = 7
100 / 4 = 25
Therefore our answer in simplest form is 7/25.
