- 15 chocolates = $9.10
- => 1 chocolate = $9.10/15
- => 1 chocolate = $0.61 (Rounded to nearest hundredth)
Hence, the cost of 1 chocolate is $0.61.
Answer:
62/78*( 1 6/8)
= 31/39*( 1 6/8)
= 31/29*( 1 3/4 )
= 31/39* 7/4
Multiply the numerator together and the denominator together
= 217/156

Answer:
Y = 3/5x + 10...slope here is 3/5. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So we need a slope of -5/3
Step-by-step explanation:
y = mx + b
slope(m) = -5/3
(15,-5)...x = 15 and y = -5
now we sub for b, the y int
-5 = -5/3(15) + b
-5 = -25 + b
-5 + 25 = b
20 = b
so ur perpendicular equation is : y = -5/3x + 20
