Abrownie recipe asks for two and one third times as much sugar as chocolate chips. if three and one half cups of sugar is used, what quantity of chocolate chips would then be needed, according to the recipe?

1 1/2 cups.

Step-by-step explanation:

If the quantity of chocolate chips is x cups then:

x * 2 1/3 =  3 1/2

x * 7/3 = 7/2

x = 7/2 / 7/3

x = 7/2 * 3/7

x = 3/2 = 1 1/2 cups.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
