Answer:
It costs $42.43
Step-by-step explanation:
Lets explain how to solve the problem
- The cost of 
kilogram of candy is $7.5
- We need to find the cost of 
kilogram
We can use the ratio to find the answer
======= Dollar : Kilogram
======= 7.5 :
======= c :
By using cross multiplication
∴ c × = 7.5 ×
∵ = 
∴ = 
∴ c × = 7.5 ×
∴ c × = 
Divide both sides by
∴ c = ÷
Change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∴ c = × 
∴ c = 
= 42.43 dollars
∵ c represents the cost of kg
∴ It costs $42.43
Answer: The slope of the line is m, which is 3.
Step-by-step explanation:
Don’t mind the two parts I scribbled out, I didn’t a few extra steps when I misread the instructions. Just look at the top left corner and the right side of how I solve for the slope.
Answer:
11) c = 16.1
12) c = 11.4
Step-by-step explanation:
11)
a² + b² = c²
8² + 14² = c²
64 + 196 = c²
c² = 260
c = 16.1
12)
a² + b² = c²
7² + 9² = c²
49 + 81 = c²
c² = 130
c = 11.4
Answer: No solution
<u>Step-by-step explanation:</u>
1st number: x
2nd number: x + 2
- reciprocal of the larger is
- 4 times the reciprocal of the smaller is 4
- reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4 -
- the result is 56: 4 - = 56
Solve the equation:
4 - = 56
- 
= 56(x(x + 2))
4x + 8 - x = 56x² + 112x
3x + 8 = 56x² + 112x
0 = 56x² + 109x - 8
Use the quadratic formula to solve:
x = 
The result is NOT AN INTEGER so there is NO SOLUTION
Answer:
67 mph
Step-by-step explanation:
Well the average speed is miles per hour so simply its 301.5 miles and 4.5 hours
which to see how many miles in one hour:
301.5/4.5 = 67
