Step-by-step explanation:
Answer:
Choice D
Step-by-step explanation:
Given division problem is 
Now we need to find about which of the given choices shows the division problem below in synthetic division form.
To convert into synthetic division form, we set denominator =0 so we get
x+2=0 or x=-2
Hence we divide by -2
Now collect coefficients of numerator for the dividend part
Coefficients of
are 5 9 -6
Hence correct choice is D
10x+6y=152
5x+3y=76
7x+12y=200
-20x-12y=-304
-13x=-104
x=8
40+3y=76
3y=36
y=12

Answer How many liters of a 20% acid solution should be mixed with 30 liters of 50% acid solution in order to obtain a 40% solution. ... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That is 18 liters pure acid That is 45 liters solution *0.45 pure acid=18 liters.
Step-by-step explanation:
93 / 12 = 7.75
so Lester earns $7.75 a hour.
if he earns $62 how many hours did he work.
so 62 = 7.75 (h)
62/ 7.75 = 8
so he worked 8 hours.
