Answer:
A=B maybe ...
what is that symbols of a and b
C. 40
30x30=900
40x40=1600
total of 2500 take the square root and your left with 50 so everything balances out
12960 seconds equals 3.6 hours.
since its 3.6 hours we need to calculate it so one minute = 60 seconds and 60 minutes = a hour so those are the basics to solve this. now u have add 1 minute of 60 minutes to equal just one hour which gets u 3 if u do it 3 times.
M-(M x 0.16) and M-(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract.
4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9
