Answer:

Step-by-step explanation:

Negative 2/3 means -2/3

Hence;

1 + (-2/3) - (-m)

= 1 - 2/3 + m (positive x negative = negative, negative x negative = positive)

Substituting 9/2 for the value of m

= 1 - 2/3 + 9/2

The L.C.M = 6

= ( 6 - 4 + 27)/6

= 29/6

one fruit punch had 40% fruit juice and another is 90% fruit juice. how much of the 40% punch should be mixed with 30 gallons of

sashaice [31]

A = fruit juice 40%

B= 90% juice

then

30 gallons + A = 55• C/100

30 gallons + N • (40/100) = (30 + N)• (55/100)

Now solve this equation, for N

3000 + 40N = (30+N) •55

then

3000 - 1650 = 55N - 40 N = 15N

1350 = 15 N

then

N= 1350/15 = 90

Then answer is

Should be mixed 90 gallons of 40% fruit punch

Step-by-step explanation:

The radius is the distance from the centre of the circle to a point on the circumference.

Use the distance formula to calculate the radius r

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)

r = $\sqrt{(1+3)^2+(5-2)^2}$

= $\sqrt{4^2+3^2}$

= $\sqrt{16+9}$

= $\sqrt{25}$ = 5
