$20.50 x .3 = 6.15
20.50 - 6.15 = $14.35
The book is now $14.35
Answer:
n = 12
Step-by-step explanation:
By applying geometric mean theorem in the given right angle triangle,
BD² = AD × DC
Now substitute the values of each side given,
n² = 6 × 24
n² = 144
n = 12
Answer:
XXL = $19.75
Box of Breadstick = $3.5
Step-by-step explanation:
Given that:
Let :
cost per XXL pizza = x
Cost per box of bread stick = y
4x + 2y = 86 - - - (1)
6x + 4y = 132.50 - - - (2)
From (1): Divide (1) by (2)
2x + y = 43 - - - (3)
y = 43 - 2x
Substitute y = 43 - 2x into (2)
6x + 4(43 - 2x) = 132.50
6x + 172 - 8x = 132.50
-2x + 172 = 132.50
-2x = 132.50 - 172
-2x = - 39.50
x = $19.75
y = 43 - 2x
y = 43 - 2(19.75)
y = $3.5
No, answer would be 2 because -9/3 is -3 and -3 plus 2 is -1
