Answer:
x=
1/2
and y=3
Step-by-step explanation:
Let's solve your system by substitution.
y=10x−2;2x+y=4
Step: Solvey=10x−2for y:
y=10x−2
Step: Substitute10x−2foryin2x+y=4:
2x+y=4
2x+10x−2=4
12x−2=4(Simplify both sides of the equation)
12x−2+2=4+2(Add 2 to both sides)
12x=6
12x
12
=
6
12
(Divide both sides by 12)
x=
1
2
Step: Substitute
1
2
forxiny=10x−2:
y=10x−2
y=10(
1
2
)−2
y=3(Simplify both sides of the equation)
Answer:
x=

A=pi(r)^2
We have the diameter. To get the radius divide it by 2.
The radius now is equal = 13.
Pi=3.14
Distribute it to the equation... A=3.14(13)^2
The area is equal = 530.66
Answer:
50 Students
Step-by-step explanation:
24% = 0.24
12/total amount of students = 0.24
12/0.24 = total amount of students
total amount of students = 50
