d) 14 1/2

Step-by-step explanation:

First, let's multiply 3(pinapple swirl cake) to find the total cups of flour for that.

3(2 1/3)=3(7/3)=3/1(7/3)=21/3=7

So, the total cups of flour for the pinapple cakes are 7 cups.

Next, let's find the chocolate cakes.

5(1 1/2)=5/1(3/2)=15/2=7 1/2

Add 7 1/2 and 7 together, and we get 14 1/2, or d)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
