8 Is the unit rate. For 9/27
Answer:
84°
Step-by-step explanation:
Let the two complementary angles be x and y.
If the measure of an angle is 14 times the other, then x = 14y...... 1
Since the two angles are complementary, their sum will be 90° i.e x+y = 90° ...... 2
Substitute equation 1 into 2
14y+y = 90
15y = 90
y = 90/15
y = 6
Since the angle is x = 14y
x = 14(6)
x = 84°
Hence the measure of the angle is 84°
Answer:
A and B.
Step-by-step explanation:
4x^2 - 4x - 3 = 0
4x^2 + 2x - 6x - 3 = 0
2x(2x + 1) - 3(2x + 1) = 0
(2x - 3)(2x + 1) = 0
x = 3/2, -1/2.
Answer:
x = 52
Step-by-step explanation:
To answer this question, we need to set up a system of linear equations:
x = 4y - 8
(1/2)x + y = 11 (Note: Please use ( ) around fractions such as this 1/2, to
eliminate possible ambiguity)
We want to find the x-coordinate, so should start by elilminating y from this system of equations.
Do this by multiplying the 2nd equation by -4. This results in
-2x - 4y = -44
Combine this result with x = 4y - 8:
x = 4y - 8
-2x - 4y = -44
----------------------
-x = -52 (Notice how the "y" terms cancel each other out.)
Dividing both sides by -1 produces the desired answer: x = 52
