Answer: 72.4
Step-by-step explanation:
Fraction of six-grade students that have at least one pet = 2/5
Number of sixth graders at Brunswick Elementary school = 181
The number of sixth graders that own own pets will be:
= 2/5 × 181
= 72.4
Hi!
We can set up a proportion then cross multiply to solve this.
45 x 100 = 4500
4500/18 = 250
The answer is 250
Hope this helps! :)
Answer:
x + y = 180
and,
x = 3y
Step-by-step explanation:
Data provided in the question:
Total area of the farm = 180 acre
x represents the acre in which corn is planted
y represents the acre in which wheat is planted
Thus,
Area of corn + Area of wheat = Total area of farm
x + y = 180 ................. (1)
also,
From the statement, farmer wants to plant three times as many acres of corn as wheat
we can conclude
Area of corn = 3 times the area of wheat
or
x = 3y ................(2)
So, we have system of linear equations that represent the situation as
x + y = 180
and,
x = 3y
