Answer:
m=-1
Step-by-step explanation:
Since you no what x is you can subst. it into the second equation so 2m+11-9=0 so 2m+2=0 then subtract 2 from both sides 2m=-2 than divide m=-1
A. 35/100 * 240 = 35 * 240 / 100 = 84
B.125/100 * 80 = 125 * 80 /100 = 100
C. 60/ 75% = 60 * 100 / 75 = 8
D. 45 / 15% = 45 * 100/ 15 = 300
I don't know how to explain but the answer is 2.4.
