Look at the explanation.
I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
Multiply 6 by $16.50 to get the total amount = $99
now to get the percentage discount : 99-90 (which is the difference) / 99 (original price of what it should have been )
and then multiply by 100 to get the percentage discount

Step-by-step explanation:
The master chief has three and a half cookies i.e.
numbers of cookies.
Again the arbiter has five and three quarters of a cookie i.e.
number of cookies.
Therefore, in total there are
numbers of cookies.
If we divide the total number of cookies in to equal parts and distribute to then then each of them will get
numbers of cookies. (Answer)
Answer:
242
Step-by-step explanation:
7(6*6)-10
7(36)-10
252-10
=242
The relation between pressure and volume is given as
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²
When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³
Answer: 20 in³
