Answer:16.5
Step-by-step explanation:
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
Answer:
(3, 5, 2)
Step-by-step explanation:
Many authors interpret the triangle inequality to mean the sum of the two short sides must <em>exceed</em> the length of the long side. For side measures 2, 3, 5, the sum of the two short sides is <em>exactly equal</em> to the long side, in violation of the triangle inequality. Hence (3, 5, 2) is not a triangle.
___
<em>Comment on the triangle inequality</em>
Other authors allow the "or equal to" case, meaning sides of lengths 2, 3, 5 will be considered to be a triangle because 2+3=5. This interpretation of the triangle inequality will result in <em>no solution</em> to your question.
A (3, 5, 2) "triangle" will look like a line segment of length 5. It will have an area of zero.
Answer:
96
Step-by-step explanation:
144/12= 12 ( each hour)
12( times) 8=96
Since they got 144 for 12 hours you have to divide the hours by the money to get the amount earned ever hour so you divide the total amount by the hour then use the information you got and then you multiply the amount of money by 8
Answer:
950
Step-by-step explanation:
As, 45% will be vanilla, and 17% will be strawberry
So chocolate will be = 38%
As, 45%+17%+38% = 100%
So 38% of 2,500 = chocolate cones
= 38/100 x 2,500 = 950
So the number chocolate ice cream cone sold is 950.
