Answer:
y = - 24
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = - 3
k = 
= 
= - 4
y = - 4x ← equation of variation
When x = 6, then
y = - 4 × 6 = - 24
Do them backwards and you will get the answer
Answer:
Lima bean
Step-by-step explanation:
It sounds weird but a cell is actually the size of a lima bean
In order to find the scale they are using first you must divide 12 by 3.75.
But since we get to estimate, the 3.75 will be made into a 4 because it's the whole number closest to 3.75.
12/4=3
Take your 3 inch scale and multiply it by 3 (we are using 3 instead of 2.8 because it's a whole number) to get the real life fence size.
3x3=9
The fence is about 9 feet.
