Answer:
15 students
Step-by-step explanation:
No. of boys students = No. of all students - No. of girls
no. of boys =50-15 = 35 boys
the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys
and the girls that will play the match are 5 girls
so, no of students chosen to play = 5+10=15 students
Let the original price of headphone = x
there is 40% discount which is 0.40x
so the payment price will be x-0.40x = 0.60x
Given that paid amount is $36
so both will be equal
0.60x = 36
x=36/0.60
x=60
Hence final answer is $60.
Answer:
A. (3, -2)
Step-by-step explanation:
A 180° rotation about the origin places an object in the quadrant diagonal to the one it started in. Moving the object two 90° turns, will place it in a coordinate that will make the values of 'x' and 'y' opposite to the initial value. In this case, vertex A has an initial point of (-3, 2), so after a 180° rotation, it would be (3, -2).
Answer:
Step-by-step explanation:
You basically minus the x's
Then get your equation e.g a +b+c=.....
Then find x on its own e.g 2x=4
X= 2
Answer:
7
Step-by-step explanation:
Listing the factors of each number is one way, that is
factors of 35 : 1, 5, 7, 35
factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
The common factors are 1 and 7
The GCF is therefore 7
