Answer: 15
Step-by-step explanation:
Each side of the smaller triangle is scaled up by 2.5.
4x2.5=10
8x2.5=20
6x2.5=15
Answer:
Option C is the correct answer.
Step-by-step explanation:
Per week earning = $8
Amount in savings = $12
y = Total amount
x = Number of weeks
y = 8x + 12
Where we can put x=4 to calculate earning of 4 weeks.
y = 8(4) + 12
y = 32 + 12 = $44
Therefore,
Option C is the correct answer.
Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.
The answer is (1/5=0.2) (4/20=0.2)
