Andrea baked 3 cakes for her cousin's birthday. Each cake requires 3 1/4 cups of flour. How many cups of flour was left if she had 15 cups in the beginning? *

5 1/4 cups of flour

Step-by-step explanation:

Each cake requires = 3 1/4 cups of flour

She has = 15 cups of flour

She made 3 cakes

Number of flour used for 3 cakes = 3 1/4 cups of flour × 3

= 13/4 × 3

= 39/4

= 9 3/4 cups of flour

Flour remaining = Total flour - used flour

= 15 - 39/4

= 60-39/4

= 21/4

= 5 1/4 cups of flour

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
