Answer:
20 males and 7 females
Step-by-step explanation:
Let's say the number of females is x and the number of males is y.
We know that the total number of students is 27, which can also be written as x + y. So, these two expressions are equal: x + y = 27.
There are 13 fewer females than males, so: x = y - 13.
Now, we can use substitution to solve this system of linear equations.
Since x = y - 13, we can plug in y - 13 for x in x + y = 27:
x + y = 27 ⇒ (y - 13) + y = 27 ⇒ 2y - 13 = 27 ⇒ 2y = 40 ⇒ y = 20
Then, we use this value of y to solve for x:
x = y - 13 = 20 - 13 = 7
Thus, there are 20 males and 7 females.
Hope this helps!
The perimeter would be 40 square meters because the area of the square is side times side and the side equals ten so 10+10+10+10=40
Answer:
A) 5km, 25km B) 2.5km, 12.5km
Step-by-step explanation:
A)Claire runs 10 km in 1 hour.
she runs 10/2=5km in 1/2 hour.
in 2 1/2, she runs 10*2 1/2=25km
B)Malia runs 5 miles in 1 hour.
she runs 5/2=2 1/2km in 1/2 hour.
in 2 1/2, she runs 5*2 1/2=12 1/2km
