Melissa got two puppies, Ben and Sadie. When she got them, Sadie was 5 pouds less than Ben. If Sadie's weight quadrupled after one year, write an expression using parentheses to show Sadie's weight.

4(B - 5) = S

Step-by-step explanation:

B = Ben

S = Sadie

We know that Sadie was 5 pounds less than Ben, with this information, we can create the expression B - 5 = S.

We are then told that after one year, Sadie's weight quadrupled (4), to find out how much Sadie weighs, we need to multiply her current age by 4, but we do not know her age yet, so use the equation we have already.

B - 5 = S

Since we are looking for her age quadrupled, we need to multiply the left side of the equation by 4.

[4(B - 5) = S]

This also fits us having to use parenthesis.

both equations and proportions are better.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
