X + 0.4[6-x] = 0.5*6 0.6x = 0.6 x = 1 gallon the answer is, "one gallon".
Answer:
Step-by-step explanation:
Part (A).
Angles ABC and CBD are the supplementary angles.
Therefore, m(∠ABC) + m(∠CBD) = 180°
Now substitute the measure of each angle in the equation,
(5x + 12)° + (13x + 24)° = 180°
18x + 36 = 180
18x = 180 - 36
18x = 144
x = 8
Part (B).
m∠ABC = (5x + 12)
= 5(8) + 12
= 52°
m∠CBD = (13x + 24)
= 13(8) + 24
= 104 + 24
= 128°
Part (C).
We can check the results by adding measures of these angles.
m∠ABC + m∠CBD = 52 + 128
= 180°
Therefore, both the angles are supplementary angles which is already given.
34 gallons. 204 miles divides by 6 is equal to 34.
Answer: 158
Step-by-step explanation:
158.297
It rounds to 158
since 0.297 < 0.5
The temp. rose by 17 degrees and then fell by 17 degrees. This means that the net change in temp over the course of the day was zero.
