The first thing we must do for this case is to define variables:
x: text messages
Y: pictures
We write the system of equations:
0.05x + 0.10y = 4
x = y + 5
Solving the system we have:
x = 30
y = 25
Answer:
you send:
30 text messages
25 pictures
You first have to turn 4 2/8 and two and 34/8 and then you have to put one over 64 and multiply cross if there is any corrections to make you just have to simplify and do that
The Least Common Measure for 12 and 9 is:
LCM(12, 9) = 36
The smallest total number of hot dogs is 36.
<span> 3x+5y = 15
5y = -3x + 15
y = -3/5(x) + 3
hope it helps
