Answer:
The value of x = 0.41
Step-by-step explanation:
∵ 
Let 
∴ 
∴ 6y² - 5y = 6
∴ 6y² - 5y - 6 = 0 ⇒ factorize
∴ (3y + 2)(2y - 3) = 0
∴ 3y + 2 = 0 ⇒ 3y = -2 ⇒ y = -2/3
∴ 2y - 3 = 0 ⇒ 2y = 3 ⇒ y = 3/2
∵ 
∴
⇒ refused
(
never gives -ve values)
∵
⇒ insert <em>ln</em> in both sides
∵
⇒ <em>ln</em>(e) <em>= 1</em>
∴
∴ x = ln(3/2) = 0.41
Answer:the number of cars that were washed is 50
Step-by-step explanation:
Let x represent the number of cars that members of a senior class.
Let y represent the number of pick-up truck or a sport utility vehicle that members of a senior class.
They charged $3 to wash a car and $5 to wash a pick-up truck or a sport utility vehicle and they earned a total of $275. This means that
3x + 5y = 275 - - - - - - - - -- - -1
They washed a total of 75 vehicles. This means that
x + y = 75
Substituting x = 75 - y into equation 1, it becomes
3(75 - y) + 5y = 275
225 - 3y + 5y = 275
- 3y + 5y = 275 - 225
2y = 50
y = 50/2 = 25
Substituting y = 25 into x = 75 - y, it becomes
x = 75 - 25 = 50
If it takes 2 cups to make 12 muffins, then one cup will make six, half a cup will make 3, 1/4 will make 1 1/2 muffins, and 1/6 cup will make 1 muffin.
If you want 4 muffins, simply multiply 1/6 × 4 to get 2/3 cup.
1. Right
2. Left
