Answer:
5q + 5q + 5
2q + 5 + 8q
5(2q + 1)
Step-by-step explanation:
First set up your two equations:
x + y = 90
x = 2y - 30
Then substitute what x equals in the second equation into the first equation:
(2y -30) + y = 90
Now solve for y:
3y -30 = 90
3y = 120
y = 40
Then use y = 40 and substitute the value for y into one of your original equations and solve for x. I'll choose the first one, but either one will work.
x+ 40 = 90
x = 50
So your solution is x = 50 and y = 40

Answer:
1.854826e+134
Step-by-step explanation:
To answer a question like this, you need to know that the factorial of a number is the multiplication of all the posible whole numbers from 0 to the original number. Thus, this problem can be solved calculating 88! (88 factorial) = 88 * 87 * 86 * 85 * 84 * … * 3 * 2 * 1, so the final answer is a very big number, 1.854826 * 10 ^134
