Answer: B = 18 degrees
C = 48 degrees
Step-by-step explanation:
Complimentary angles are angles whose sum is 90 degrees.
Angle A, angle B, and angle C are complementary angles. This means that
A + B + C = 90- - - - - - - - - - - - -1
The measure of angle C is twice the measure of angle A. If the measure of angle A is 24 degrees, it means that the measure of angle C would be 2 × 24 = 48 degrees.
Substituting A = 24 and C = 48 into equation 1, it becomes
24 + B + 48 = 90
72 + B = 90
B = 90 - 72
B = 18 degrees
The answer is A becaues 119 thousand times 10 equals 1190000
then you divide it by 100 to get A.119 hunderths
Answer:
x = 3/2 or 1.5.
y = -1/2 or -0.5.
Step-by-step explanation:
Solve for one equation, one variable.
2x + 4y = 1
subtrract 4y from both sides.
2x = 1 - 4y
divide by 2 to get x by itself.
x = 1/2 - 2y
Now that we have this, we can put it into the other equation.
3x - 5y = 7
Substitute variable.
3(1/2 - 2y) - 5y = 7
Distribute the 3.
1.5 - 6y - 5y = 7
Combine terms.
-11y + 1.5 = 7
Subtract by 1.5.
-11y = 5.5
Divide by -11.
y = -1/2, or -0.5.
Now we can find x. Substitute this into the initial equation.
2x + 4y = 1
Substitute variable.
2x + 4(-1/2) = 1
Multiply.
2x + (-2) = 1
Simplify.
2x - 2 = 1
Add 2 to both sides.
2x = 3
Divide by 2.
x = 3/2, or 1.5.
x = 3/2 or 1.5.
y = -1/2 or -0.5.
Answer:
B and D
Step-by-step explanation:
A and C both show linear relationships (in this case negative). B is a parabolic curve, and D is a non-linear tread.
