Johnny borrows a lemonade stand from Tom for M days at the price of $3 a day. How much would he make in total, if he made $75 a day?
Answer:
radicals or complex numbers
Step-by-step explanation:
A "rationalized" denominator consists entirely of a real number or variable expression with real coefficients. Preferably, any number(s) will be integer(s).
Answer:
49
Step-by-step explanation:
x + 100 + 31 = 180
x + 100 + 31 - 100 - 31 = 180 -100 -31
x = 49
To answer this, write a system of equations and use one to solve the other.
b + 2c = 2000 or b = 2000 - 2c (substitute this in for b in the 2nd equation)
2b + 3c = 3300
2 (2000 - 2c) + 3c = 3300
4000 - 4c + 3c = 3300
4000 -c = 3300
-c = -700
c = 700 calories
He burned 700 calories per hour canoeing and 600 calories per hour playing basketball (2000 - 2 x 700).
