write the following as algebraic equations-do not solve
1. angle a and angle b are complementary.
2. segment ab is 6 more than twice the length of segment dc.
3. twice the sum of a number and 7 is increased by 5. the result is 25.
4. half a number, increased by 11 is twice the same number decreased by 5.

a +b=,ab +6+DC,7*5=35,11-5=6

Step-by-step explanation:

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;

what am i looking for finish the question.
