<u>Answer</u>:
c = 9
<u>Explanation</u>:
given: f(x)=3x-7
<em>if f(c) =20</em>
To solve this replace x with c and then y is 20.
<u>Solve</u>:
3c - 7 = 20
3c = 27
c = 27 ÷ 3
c = 9
The equation for the horizontal line is
y=3
This number would be 24. So 21 own football boots, 16 own a football and there are 24 children in the class. not good at math so yeah
Stack them all up in a row:
0.06
0.16
0.60
0.66
Now order them from least to greatest by each place
0.06, 0.16, 0.60, 0.66
(LOL, you TYPED them least to greatest!)

Answer:

Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is
.
Because all the angles of a triangle sum to
, we have that
.
We combine like terms on the left side to get
.
We subtract
on both sides to get
.
So,
and we're done!
