10% of what is 9...
0.10x = 9
x = 9/0.10
x = 90.....he has 90 all together
Answer:
Step-by-step explanation:
Sum a with a-s ;b with b-s so:
0.75a + 10b + a – 2b=0.75a+a+10b-2b=1.75a+8b

78×4000=312000
100×x=100x
312000÷100=3120
3120+4000=7120<----2nd month
7120×0.5=3560<----3rd month
4000<----1st month
4000+3560+7120=14680<----Your answer, this is the total of the three months.
Put x = 2 in f(x) you'll get,f(2) = 2(3) x 2 = 12. so next point could be ( 2,12)
11/8 = x / 3
cross multiply
8x = 11 * 3
8x = 33
x =33/8
x = 4.125
x = 4.1 (round to nearest tenth)
