Hello there! the answer would be x = 3/4.
You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.
4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).
4x - 1x + 4 = 8 - Combine like terms.
3x + 4 = 8 - Subtract 4 from both sides.
3x = 4 - divide both sides by 3.
x = 3/4. This is your final answer.
I hope this was helpful, have a great day! :)
Answer:
See below.
Step-by-step explanation:
The 3 angles of all triangles add up to 180 degrees.
An isosceles triangle has 2 of its angles equal.
So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.
So the other 2 angles are equal and their measure is (180 - 130) / 2
= 50 / 2
= 25 degrees.
The 2 equal angles are both 25 degrees.
Answer:
y will be 8 making z to be 9 and x does not have a value here
Step-by-step explanation:
We can find the coterminal angle by simply adding or subtracting 360° to each angle. In this problem, we need to find the smallest positive coterminal angle with 915 degrees.
It can be calculated by adding or subtracting 360° to the given angle. For positive coterminal angle subtract 360° from 915°
915-360 = 555
555-360 = 195
The positive coterminal angles: 195°, 555°, 915°, 1275°, 1635°...
The negative coterminal angles: -165°, -525°, -885°, -1245°...
Hence, the angle<u> </u><em><u>195°</u></em> is the smallest positive coterminal angle with 915 degrees
