Answer:
5(d - 2) = 45
Step-by-step explanation:
Solve the given equation for d
3(d + 1) = 4(d - 2) ← distribute parenthesis on both sides
3d + 3 = 4d - 8 ( subtract 3d from both sides )
3 = d - 8 ( add 8 to both sides )
11 = d
Then
5(d - 2) = 5(11 - 2) = 5(9) = 45
75÷500 = 0.15 multiply with a hundred to get percentage equals 15℅
$8250 - $3120 = $5130
$5130/75 = $68.40
Each band member must raise $68.40
Answer:
8 9/10
Step-by-step explanation:
89 goes into 10 8 times.
8x10=80.
89-80=9
So the answer is 8 9/10
Using the equations for tangent and secant lines:
Let the unknown length of the line inside the circle = y
6^2 = 3 x (y+3)
Simplify:
36 = 3y+9
Subtract 9 from both sides:
27 =3y
Divide both sides by 3:
Y = 9
Now add to get x:
X = 9 + 3 = 12
X = 12
