-2(-2x + 3)-x -1 = -28

x = -7

Step-by-step explanation:

Original Equation:

-2(-2x + 3) - x - 1 = -28

Add 1 to both sides.

-2(-2x + 3) - x = -27

Use distributive property

-2 · (-2x) = 4x

-2 · 3 = -6

Your equation should look like this now:

4x - 6 - x = -27

Add 6 to both sides

4x - x = -21

Subtract x from 4x

3x = -21

Divide both sides by 3

x = -7

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

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;
