Answer:

B. 7

Step-by-step explanation:

4(x-3)=16 so you have to multiply the entire equation by 4 since it is outside parenthesis

4x-12=16 then you have to add 12 to both sides to isolate 4x

+12 +12

4x=28 then you have to divide both sides by to just have x

4/4=1 28/4=7 (the 1 doesn't mater because 1x=x and x=1x)

x=7 is your answer

Sara is collecting signatures to pu on her towns ballot. So far, she has 432 signatures. This is 36% of the number of signatures

In-s [12.5K]

Sara needs to collect 1200 signatures.

Step-by-step explanation:

Let,

x be the total number of signatures she needs to collect

Given percentage = 36%

Signature collected = 432

According of statement;

36% of x = 432

$\frac{36}{100}*x=432\\$

$\frac{36x}{100}=432\\Multiplying\ both\ sides\ by 100\\100*\frac{36x}{100}=432*100\\36x=43200\\Dividing\ both\ sides\ by\ 36\\\frac{36x}{36}=\frac{43200}{36}\\x=1200$

Sara needs to collect 1200 signatures.
