To get X by itself you first bring -7 over and get X/5=-1 then multiply both sides by 5 to get X=-5
Answer:
Step-by-step explanation:
Add the -5.57 to both sides then divide it by 2 which is -0.91
Step-by-step explanation:
Suppose AB is the 3- foot high access ramp that ends at point C 20 feet along the ground and
theta is the angle of depression from the start of 3 foot high ramp at point A
Now, in ∆ ABC
m<ACB= theta ( alternate interior angle)
Therefore,
(theta) = tan⁻¹(3/20)
= 8.5°
Answer:
Constant of proportionality:
Equation:
Step-by-step explanation:
By definition, Direct proportion equations have the following form:
Where "k" is the Constant of proportionality.
In this case, let be "c" the the amount of caffeine consumed (in mg) from a glass of Diet Pepsi and "d" the number of ounces that was drank.
So, the equation that represents this relationship will have this form:
Then, the first step is to find the Constant of proportionality "k".
Knowing that:
We can substitute values into the equation:
Now, solving for "k", we get:
Therefore, we can write the following equation that represents that proportional relationship:
