Kira solved the equation in the following way. 7/2 − 2x = 11/2 7/2 − 7/2 − 2x = 11/2 − 7/2 −2x ÷ −2 = 4/2 ÷ − 2 x = −1 Describe the properties of equality that Kira used. The first step is to use the property of equality to combine the constant terms. The second step is to use the ___ property of equality to isolate the variable.

y=x+9

?

step-by-step explanation:

okay..i will pick 8!

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
