Answer:
- <u>150 pieces of candies.</u>
Explanation:
In the graph each divsion on the x-axis represents 3 <em>students </em>and each division of the y-axis represents <em>5 candies</em> left in the bowl.
Every point of the graph, i.e. every ordered pair (x, y), represents the number of candies given to the corresponding number of students.
Some pairs are:
- (0, 45), which means that when zero number of students had been given candies, there where 45 candies in the bowl.
- (3, 40), which means that 40 candies were left in the bowl after having given the candies to 3 students:
⇒ 45 - 40 = 5 candies were given every 3 students.
Since you might draw a line that passes through all the the points on the graph, the ratio of number of candies to number of students will be the same:
Thus, set a proportion:
- 5 candies / 3 students = x / 90 students
Solving for x:
- 5 candies / 3 students × 90 students = x
Therefore, <em>Mrs Wright would need </em><u>150 </u><em>pieces of candies in order to give the 90 students the same amount as she did for the 27 students.</em>
Y=mx + b and passing by (1,1)
m= 6 (given), then y = 6x+b. Calculate b:
y = 6x + b
1 = 6(1) + b
b = -5
y = 6x - 5
Answer:
lions=105 elephants=252
Step-by-step explanation:
We know that there is a total of 375 lions and elephants. We also know the ratio of those. With these two we can build an equation that gives us the exact number of each of the two species.
We can multiply the ratio by x:
(5/12)*(x/x)
now we have:
5x/12x
we input these new data into the total number of both animals:
5x+12x=357
17x=357
x=357/17
x=21
remember x is not the number of any of the animals
number of lions is 5x=5*21=105
number of elephants is 12x=12*21=252
