n% = percentage of people that chose hot chocolate
150 x n% = 72
n / 100 = 72 / 150
n = 48
= total people x hot Choco percentage
= 500 x 48%
= 240
Answer:
95.9
Step-by-step explanation:
since the hundredths place is 1 you round down so the tenths place doesn't change and remains as 95.9
Are you talking about the angles in a triangle? Your question is not clear. I'll assume you are talking about a triangle.
Angle 1 + Angle 2 + Angle 3 = 180°
4x + 15 + 2x + 16 + x = 180°
Solve for x to find Angle 3, which in this case is the value of x.
Answer:
She subtracted the two 10x's where instead you're supposed to add them together.
Step-by-step explanation:
Substitute each value of x, calculate, and if the answer equals to the given value of y, then the point does lie on y = 2x
Point A (1, -1)
y = 2(1)
y = 1
The answer is not y = -1 as given in the question, hence point A does not lie on y = 2x
-----------------------------------------------------------------------------------------------------------
Point B (1, 3)
y = 2(1)
y = 2
The answer is not y = 3 as required, hence point B does not lie on y = 2x
---------------------------------------------------------------------------------------------------------------
Point C(-2, -4)
y = 2(-2)
y = -4
The answer is y = -4 as required. Hence, point C does lie on y = 2x
-----------------------------------------------------------------------------------------------------------------
Point D(-2, 4)
y = 2(-2)
y = -4
The answer is not y = 4 as required, so point D does not lie on y = 2x.
