We need to write system of equations for this problem. Reading text we write 1 equation by 1.
first lets name our variables
x - Kiana cards
y - Gary cards
z - Monty cards
m - Willa cards
x = y-3 which we can write as y = x+3
z = x + 7
m = 2z
x + y + z + m = 74
I think easiest way to solve this is to express all variables in last equation and solve for x.
x + x+3 + x + 7+ 2x + 14= 74
5x = 50
x = 10
now we just calculate cards given to each friend
y = 13
z = 17
m = 34
Answer:
<u>The correct answer is D. 53x - 12</u>
Step-by-step explanation:
Let's find P(x), this way:
Profits = Revenue - Cost
Profit function = Revenue function - Cost function
P (x) = R (x) - C (x)
Replacing with the real values we have:
P (x) = 60x - (12 + 7x)
P (x) = 60x - 12 - 7x
P (x) = 53x - 12
<u>The correct answer is D. 53x - 12</u>
Answer:
1. 75% of 10 liters of milk = 0.75 * 10 liters of milk = 7.5 liters of milk
2. To find 75% of a number, multiply the number by 0.75.
Answer: 1.4688 x 10^6
Step-by-step explanation: Number has to be in between 1 and 10. Moved the decimal 6 places so that is your exponent
Answer:
He has to buy 4 packages of hamburgers in packages of 30 and 5 packages of hamburgers in packages of 24
Step-by-step explanation:
First we have to calculate the least common multiple (LCM) of 24 and 30
We will calculate the LCM of 24 and 30 by prime factorization method
24 = 2*2*2*3 = 
30 = 2*3*5 = 
LCM = 
LCM = 120
So number of hamburger buns = 120
Therefore, he must buy 120/24 = 5 packages of hamburgers in packages of 24 and he must also buy 120/30 = 4 packages of hamburgers in packages of 30
