Answer:
4
Step-by-step explanation:
with the information given, we can express the equation:
where is the unknown number?
to clear for first we multiply the equation by 2, to eliminate the fraction:
moving all terms with to the left:
and adding +16 to each side:
and finally, dividing by 3
the number is 4.
Answer:
C
Step-by-step explanation:
Since every side of ΔABC is dilated by 3, or triple the size
We multiply every length of ΔABC by 3
But the length of DF and FG are already done for us but DG is not, which is essential to finding the answer
7 x 3 = 21
DG = 21
5/7 = 15/21
5 ÷ 7 = 0.71
15/21 = 0.71
5/7 = 15/21
Given the graph we are asked to find the cost of one ticket. This can be seen below.
Explanation
From the graph, we can see that at the point when zero tickets had been sold, the students had raised 100 dollars. After one ticket was sold, the money increased to 125 dollars. Then after 2 tickets, it further increased by 25 dollars to 150 and so on so forth.
Therefore, we can say that the cost of one ticket is:
Answer: 25 dollars
Answer:
The graph is in the attachment.
Step-by-step explanation:
We only need two points to draw a graph of the line.
The slope-point form of an equation of a line:
<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
We have <em>m = 1/5</em> and the point (-1, -5) → <em>x₁ = -1, y₁ = -5</em>
Substitute:
We given first point (-1, -5).
Calculate other point.
Put <em>x = 4</em> to the equation of a line:
<em>subtract 5 from both sides</em>
Therefore we have second point (4, -4).
