Mary lou has 2 more nickels then pennies and she has 30 coins all together select the equation that most accurately depicts the word problem a. 2(x+2)=30 b. x+(x+2)=30 c. 2x+30=5 d. x+2=30

Step-by-step explanation:

Let the pennies be represented by = x

Let nickels be represented by = y

Mary Lou has 2 more nickels then pennies.

We get

Also given that she has 30 coins all together.

Substituting y here, we get the requires equation as:

Now, solving this we will get the value of x.

x = 14

And

So, there are 14 pennies and 16 nickels.

no its the same as every other grade

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;
