Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
15% = 0.15
15% of 71.85 is equal 0.15*71.85 ≈ 10.78
Answer:
1/6, 1/4.
Step-by-step explanation:
The theoretical probability of rolling a 2 on a single roll of a number cube is 1/6, because there are 6 numbers ( 1 to 6) on a cube.
The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is 1/4, because there are 4 different colours on the spinner.
We were told that he used 2 cups of milk to make a cake, used 1/2 cup more to make frosting and he drank 3/4 cup. Thus, the total number of cups that he used is
2 + 1/2 + 3/4
= (8 + 2 + 3)/4
= 13/4
= 3 1/4 cups
He used 3 1/4 cups in all
