Answer:
300 students
Step-by-step explanation:
Since 4/5 of students do not wear glasses, 1/5 of students do.
There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses
(1/5)x = 60 is our equation. "One-fifth of the number of students who wear glasses is 60"
Now solve for x
(1/5)x = 60
x = 300 (multiply both sides by 5 to get rid of the fraction)
I don't see the choices.
It is equivalent to 0.8r.
Answer:
ok so we know that a triangle is 180 degrees.
so i can take the info and figure out the f,g,d,i all equal 90 degrees so i can figure out that 90+51=141
180-141=39
so angle a is 39
the two bigger triangles are equal and the two smaller ones are equal...
so we know that
a=39
b=62
c=51
d=90
e=39
f=90
g=90
h=28
i=90
Step-by-step explanation:
4x + 8 = 2x + 6
-2x ----- -2x
2x + 8 = 6
----- -8 ---8
2x = -2
÷-2 ÷-2
x = -1
Hope this helps!
90° angle on a straight lines gotta be 180°
