Answer:
432 people on Friday and 658 on Saturday
Step-by-step explanation:
Lets use variables for each day
x=Friday and y=Saturday
now write two equations since you were given two different information (money and people)
$6 on Friday and $8 on Saturday with a total amount of $7856
the equation will be 6x+8y=7856
now the second equation will be for people
x amount of people on Friday and y amount of people on saturday for a total of 1090; the equation will be
x+y=1090
put them together
6x+8y=7856
x+y=1090
now you can cancel a variable but manipulating one of the equations. We'll use x, to cancel x you need make it zero so multiply the bottom by -6
6x+8y=7856
-6(x+y=1090)
6x+8y=7856 now subtract downwards, with the x cancelling
-6x-6y=-6540
2y=1316 simplify
(2y/2)=(1316/2)
y=658
insert y into x+y=1090
x+(658)=1090
-658 -658
x=432

Step-by-step explanation:
The solution 92 is how tall the basil plant becomes in two weeks after he starts recording its height.
There's 14 days in two weeks.
There's no equation shown, but I suppose it was like this:
5x+22=92
But once you insert 14 days in the equation, it'll become:
5(14)+22=92
70+22=92
92=92

I worked it out, i'm pretty sure its the answer, let me know if its wrong.
Answer:
17%
Step-by-step explanation: the possibility of rolling any of these numbers is 1/6.. the percentage for that is 16.666% and rounded to the nearest whole number makes the answer 17
