It measures the amount of space occupied by an object
Answer:
1/2x +2
Step-by-step explanation:
Let's say there are 2 teams : A & B
A leads with x points, while B score 2 points less than half of B's score (x)
B = 1/2 of B score - 2
The difference of A - B = x - (1/2x - 2) = x - 1/2x + 2 = 1/2x + 2
Answer:
14.5x + 25
Step-by-step explanation:
note that (C + R)(x) = C(x) + R(x), thus
C(x) + R(x) = 2.5x + 25 + 12x = 14.5x + 25
Answer:
x=±3 sqrt(2)
Step-by-step explanation:
3x^2 - 6 = 48
Add 6 to each side
3x^2 - 6+6 = 48+6
3x^2 = 54
Divide each side by 3
3x^2/3 =54/3
x^2 = 18
Take the square root of each side
sqrt(x^2) =sqrt(18)
x =sqrt(18)
We know sqrt(ab) = sqrt(a) sqrt(b)
x =sqrt(9)sqrt(2)
x=±3 sqrt(2)
Answer:
Adult ticket = 38
Student ticket = 17
Step-by-step explanation:
Let :
Adult ticket = x
Student ticket = y
x + y = 55 - - - - (1)
Cost per x = 3.75
Cost per y = 2
3.75x + 2y = 176.50 - - - (2)
From (1):
x = 55 - y
Put in (2)
3.75(55 - y) + 2y = 176.50
206.25 - 3.75y + 2y = 176.50
-1.75y = - 29.75
y = - 29.75 / - 1.75
y = 17
From :
x = 55 - y
x = 55 - 17
x = 38
