189 because you have to multiply by 3 twice.
33 sweets in a 7x to 4x ratio
7x + 4x = 33
11x = 33
x = 3
33 sweets can be put in a 7(3) to 4(3) ratio
which is a 21 to 12 ratio
so 21 sweets are yellow, and 12 sweets are purple to get the ratio of 7 to 4
Note:
<span>a(b) = ab = a x b = a times b

Answer:
z = -2
Step-by-step explanation:
7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)
-2z + 4 = 8 (Subtract 4 on each side)
-2z = 4 (Divide each side by -2)
z = -2
You can plug -2 back in to check, and you get:
7(-2) + 4 -9(-2) = 8
-14 + 4 + 18 = 8
8 = 8
Hopefully, this helped. Good luck!
that would be A. 312 x 10^6
we can find this by counting the zeros
312,000,000
that's 6 zeros, so that means it's 312 x 10^6
