C/3 = 6 1/7
Multiply 3 to both sides:
C = 6 1/7 * 3
Convert 6 1/7 into an improper fraction:
C = 43/7 * 3
Multiply 3 to the numerator:
C = 129/7
Convert back into a mixed number:
C = 18 3/7
Answer:
1. x=3 x=1
2. x=0
Step-by-step explanation:
We want f(x) to equal g(x)
f(x)=g(x)
1/(x-2) = (x-2)
Using cross products
1 = (x-2) * (x-2)
1 = x^2 -2x-2x+4
Subtract 1 from each side
1-1 = ^2 -2x-2x+4-1
0 = x^2 -4x+3
Factoring
What number multiplies to 3 and adds to -4
-3*-1 = 3
-3+-1 = -4
0= (x-3) (x-1)
Using the zero product property
x-3 =0 x-1=0
x=3 x=1
2. f(x)=x^2+4x+2
g(x)=(1/2)^ x+1
From the graph,we can see they intersect at x=0
We can swap the subtraction with addition to find out what ? equals to:
? - 66 = 25.
? = 25 + 66.
? = 91.
Check:
91 - 66 = 25
Answer:
6 x 0,30 = $1,80
$3,30 - $1,80 = $1,50
$1,50 - $1,25 = $0,25 (not enough money)

Also, I think that Brainly is an awesome app, but there's an app which is doing great work for me in maths, named Gauthmath. I will suggest it. Video concepts and answers from real tutors.
6 / 4.5 = x / 6
x = 6* 6 / 4.5
x = 36/4.5
x = 8
SF = 4.5 / 6 = 0.75
answer
<span>A. Scale factor 0.75, x = 8</span>
