4a + 2b = 10
you are solving for b
isolate the b
subtract 4a from both sides
4a (-4a) + 2b = 10 (-4a)
2b = 10 - 4a
divide 2 from both sides to isolate the b
2b(/2) = (10 - 4a)/2
b = (10 - 4a)/2
b = 5 - 2a
C) b = -2a + 5 is your answer
hope this helps
Answer:
It will be the graph of two lines intersecting at two comma three with text on graph that reads One Solution 2, 3.
Step-by-step explanation:
The system of equations are
y - 2x = - 1 ............ (1) and
2y - x = 4 ........... (2)
Now, solving equations (1) and (2) we get,
2(2x - 1) - x = 4
{Substituting the value of y from equation (1) to equation (2)}
⇒ 4x - 2 - x = 4
⇒ 3x = 6
⇒ x = 2
Hence, from equation (1) we get,
y = 2x - 1 = 2(2) - 1 = 3
Therefore, the solution is (2,3).
So, it will be the graph of two lines intersecting at two comma three with text on the graph that reads One Solution 2, 3. (Answer)
It would be 32.15 meters
You can draw a right triangle (Observe the figure attached. It is not drawn to scale), where "x" is the the amount of meters the street rises over a horizontal distance of 120 meters.
You need to use the following Trigonometric Identity:
In this case, you can identify that:
Then, knowing these values, you can substitute them into:
And finally, you must solve for "x" in order to find its value.
To multiply two fractions together, multiply the numerators of both fractions together and same goes for the denominators.
Simplify.
So, 1/3 is the answer.
