The coffee cup can hold 7/9 of a pint of liquid. If Emily pours 2/3 of a pint of coffee into a cup, how much more milk can she a
Orlov [11]

1/9 pints of milk can be added by a customer

Step-by-step explanation:

We have to subtract simple fractions to find the amount of milk that can be added to a cup of coffee

Given

Total Capacity of a cup = 7/9 pints

Coffee to be added in a cup = 2/3 pints

So in order to find the amount of milk that can be added we have to subtract the amount of coffee from the total capacity of cup.

So,

Hence,

1/9 pints of milk can be added by a customer

Beef hope me I need you to answer the question. What is n * 54 - 688-20 =???³
blsea [12.9K]

Answer:n= 1/3d - 2/3m

Step-by-step explanation:

d=2m+3n

Step 1: Flip the equation.

2m+3n=d

Step 2: Add -2m to both sides.

2m+3n+−2m=d+−2m

3n=d−2m

Step 3: Divide both sides by 3.

3n/3 = d-2m/3

Therefore

n= 1/3d - 2/3m

Hope this helps!

Plz name brainliest if possible.

Answer:

n = d - 2m

        3*

Step-by-step explanation:

First we want to get n alone on one side, so we should subtract 2m from both side;

d = 2m + 3n

3n = d - 2m

Now to get n by itself, we need to divide by 3 from both sides;

3n = d - 2m

n = d - 2m

        3*

*Pretend there is a fraction bar between d - 2m and 3

Find the equations of the tangents to the curve x=9t2+3, y=6t3+3 that pass through the point (12,9).
Xelga [282]

Answer:

The equation will be "y=x-3".

Step-by-step explanation:

Given:

Points (12, 9) = (x, y)

⇒ x=9t^2+3

then,

 \frac{dy}{dt}=18t

or,

⇒ y=6t^3+3

then,

 \frac{dy}{dt}=18t^2

⇒ \frac{dy}{dx}=\frac{18t^2}{18t}

        =t

By using the point slope form.

The equation of tangent will be:

⇒ y-9=1(x-12)

   y-9=x-12

          y=x-12+9

          y=x-3

9x+7y=7 find the slope
Jet001 [13]

Answer:

-9/7

Step-by-step explanation:

Put the equation into y = mx + b form, by first isolating y:

9x + 7y= 7

7y = -9x + 7

Divide each side by 7:

y = -9/7x + 1

So, -9/7 is the slope.
