Answer:
a = 10
Step-by-step explanation:
Since the quantities vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the point (2, 5 ) with x = 2 and y = 5
k = = = 2.5
y = 2.5x ← equation of variation
Using the point (4, a) with x = 4, then
y = a = 2.5 × 4 = 10
Answer:
D
Step-by-step explanation:
"The slope of AB is different than the slope of BC" the slope are on the same straight line, so this is incorrect! It doesn't matter which portion of the line you look at, the slope will always be the same.

X=5.1 repeating
this can be found by dividing 230 by 45, and is tested by plugging in the value of x.
6 times -5/12 is -2 1/2.
-2 1/2 minus 3/4's is -3 1/4.
The answer is -3 1/4.
