Sophia used 1/3 of an ounce of cheese to make 1/12 of a pound of pizza dough. How l many ounces of cheese are needed to make a pound of pizza dough?

4 pounds

Step-by-step explanation:

1/3 x 3 = 1

1/12 x 3 = 3/12 = 1/4

to get one whole, multiply by 4

1/4 x 4 = 1

1 x 4 = 4

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
