3*pie(or p)+20
It is $5 per pie.
We know the answer has to end is 0 or 5 since all multiples of 5 end it those. The first time 3 goes into 0 or 5 is 15. (3*5=15). You substitute to get 3*5+20=35. You sell 7 pies because 7*5=35, which is the cost for the making of the pies and the rolling pins.
Answer:
4) J
5) D
Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7
Answer:
Acute
Step-by-step explanation:
This should be an acute triangle because if this was a right angle, then the three sides should be figured out by the Pythagorean Theorem.
An obtuse angle wouldn't be right either, you need an angle to be over 90.
Answer:
2. is x = -3
Step-by-step explanation:
-3( x - 3) = 12
multiply the things in the () by -3
-3x+9=12
subtract 9 from both sides
-3x+9-9=12-9
-3x=3
divide both sides of the equation by -3
x = -3
Answer:
1 minute and 4 seconds
Step-by-step explanation:
5 hours - 1hour 20mins = 3hours 40 mins
3 hours 40 mins = 220 minutes
236 / 220 = 1.07272... x0.6 x 100 = 64.36... seconds
1 minute and 4 seconds
