Option A is the answer of this question.
Sean reads 60 minutes on wednesday
<em><u>Solution:</u></em>
Given that,
Let "x" be the number of minutes read on monday
Let "y" be the number of minutes read on tuesday
Let "z" be the number of minutes read on wednesday
<em><u>He reads 3 times as many minutes on Tuesday as he does on Monday</u></em>
Number of minutes read on tuesday = 3 times the number of minutes read on monday
y = 3x --------- eqn 1
<em><u>He reads 4 times as many minutes on Wednesday as he does on Monday</u></em>
Number of minutes read on wednesday = 4 times the number of minutes read on monday
z = 4x ------- eqn 2
<em><u>Sean reads 45 minutes on Tuesday</u></em>
y = 45
<em><u>Substitute y = 45 in eqn 1</u></em>
45 = 3x
x = 15
<em><u>Substitute x = 15 in eqn 2</u></em>
z = 4(15)
z = 60
Thus he reads 60 minutes on wednesday
Answer:
1 cup of brown sugar to 2 teaspoon of baking soda
Step-by-step explanation:
Given that 1.25cups of all-purpose flour, 110grams of butter, half cup of brown sugar and 1 teaspoon (tsp) of baking soda is needed to make 12 cookies. Therefore to make 24 cookies, double of this value would be needed.
Hence, 2.5 cups of flour, 220 grams of butter, 1 cup of brown sugar and 2 teaspoon of baking soda would be needed to make 24 cookies.
The ratio of brown sugar is to baking soda is to butter to make 24 cookies = 1 cup / 2 teaspoon = 1 cup of brown sugar to 2 teaspoon of baking soda
