Step-by-step explanation:
it is 12 because 12 - 7 is 5 the number 4 is the number multiplied by 3
I must assume that you meant the following:
10(Q-3R)
P = ----------------
R
Multiplying both sides by R, we get PR = 10R(Q-3R), or PR = 10RQ - 30R^2.
Rearranging these terms so that powers of R are in descending order:
30R^2 - 10RQ + PR = 0
Factoring out R, we get
R(30R - 10Q + P) = 0. This has two solutions:
R = 0, and 10Q - P
30R = 10Q - P, so that R = --------------
30
Answer:
The answer is B. $11.50 each
Step-by-step explanation:
2 pizzas @ $11 each is $22
3 garlic bread orders @ $4 each is $12
2 pitchers of soda @ $6 each is $12
$22+$12+$12 = $46
4 friends are splitting it evenly.
$46 divided by 4 = $11.50
