Answer:
x is 3
Step-by-step explanation:
6 (x + 1) = 24
6 (x) + 6(1) = 24
6x + 6 = 24
Subtract 6 on both sides
6x + 6 - 6 = 24 - 6
6x + 0 = 18
6x = 18
x = 18/6
x = 3
Answer:
Step-by-step explanation:
(7/12) of 840 attended the concert:
(7/12)*(840) = 490 students attended the Spring Concert.
(840 - 490) = 350 did not attend
(350/840) is the fraction of students who did not attend. This can be reduced to (35/84)
(350/840) = 0.4167 or 41.67% did not attend.
Answer:
8 hours
Step-by-step explanation:
because each hour that goes by the buses go a distance of 117 miles apart from each other (53+64) you must divide the total distance by the 117 mph distance for a total of 8 hours (936 / 117 = 8)
Answer:
2x^2-10x+3
4x-10x+3
-6x+3
Step-by-step explanation:
Answer:
27.6°
Step-by-step explanation:
It can help to draw a diagram.
The angle of interest is the angle in a right triangle that has 23 ft as its adjacent side and 12 ft as its opposite side. The tangent relation is helpful:
Tan = Opposite/Adjacent
tan(d) = 12/23
The inverse tangent function is used to find the angle when you know the tangent:
d = arctan(12/23) ≈ 27.55°
The angle of depression is about 27.6°.
