Drew adds 1/2 cup of wheat flour and 2 3/4 cups of white flour to his muffin batter. How many cups of flour does Drew add?

Answer 4/91  I don't know I'm not good at math but I hope it's right :)

Step-by-step explanation:  Convert mixed numbers into improper fractions: 22/3/4 = 91/4

= 1 ÷ 91/4

Convert element to fraction: 1 = 1/1

= 1/1 ÷ 91/4

Apply the fraction rule: = 1/1 x 4/91

Apply rule: a/a = 1

1/1 = 1

= 1 x 4/91

Multiply: 1 x 4/91 = 4/91

= 4/91

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
