To solve for a variable, we simply need to isolate the variable and simplify all other terms. We can do this by performing the opposite operations to both sides.
In this case, we also need to remember that if our fractions have different denominators, we multiply the numerator and the denominator by whatever value makes them have equal denominators. That is 3, here.
z-4/9-1/3=5/9
+4/9 +4/9
z-1/3=9/9
z-3/9=9/9
+3/9+3/9
z=12/9
Using the math above, we can see that z=12/9 or 1 1/3.
Step-by-step explanation:
15/35 = y/84
to find what value of y makes the proportion true, you actually just need to solve for y.
15/35 = y/84 ... first, multiply both sides by 84
(15*84)/35 = y
1260/35 = y
36 = y
so, these values are proportional when y = 36. you can check this by getting the decimal of both and seeing if they're equal:
(15/35) = 0.428
(36/84) = 0.428
Answer:
Part 1) The measure of arc EHL is
Part 2) The measure of angle LVE is
Step-by-step explanation:
step 1
Let
x-----> the measure of arc EHL
y----> the measure of arc EVL
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
so
we have
substitute
------> equation A
Remember that
-----> equation B ( complete circle)
substitute equation A in equation B and solve for x
Find the value of y
therefore
The measure of arc EHL is
The measure of arc EVL is
step 2
Find the measure of angle LVE
we know that
The inscribed angle measures half that of the arc comprising
Let
x-----> the measure of arc EHL
we have
substitute
