If shamans has 3&amp;1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcak
Kobotan [32]

Answer:

43.3 cupcakes

Step-by-step explanation:

If shamans has 3&1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcakes can she make

From the above question

1/ 13 cup = 1 cup cake

3 1/3 cups = x

Cross Multiply

1 /13 × X = 3 1/3 × 1

x = 10/3 ÷ 1 /13

x = 10/3 × 13/1

x = 130/3

x = 43.333333333 cupcakes

What’s the equation of the line that be that passes through (4,2) and is parallel to the line y=2x-1
podryga [215]

y=mx+b

because the y=2x-1, so m=2

because we know (4.2), so we can bring it in to the function:

2=2x4+b

2=8+b

b=-6

So the other one is: y=2x-6

in other way it's 2x-y=6

Which means the answer is B.
