Step-by-step explanation:
Use this formula: T=a*(1+m%)^n (T: result; a: initial money; m:interest; n:months)
Answer:
75% of x
Step-by-step explanation:
Distance spunky covers = distance to chicken
20r = 15 + 20v
It's the last option then
20r - 15 = 20v
Asking someone else to start from scratch and explain everything when you yourself have not done or shared anything is a BIG and unrealistic order.
Could you not at least share your thoughts as you read through each of the four problems?
Let's take a look at the 2nd problem (#17):
"Three times the sum of two times m and 5 is 4 less than 8 times m to the 2nd power." You must be able to translate a word problem like this one into algebraic symbols.
3(2m+5) = 8m^2 -4 (This is the desired answer)
Then 6m + 15 = 8m^2 - 4 => 8m^2 - 6m - 4 - 15 = 0 (after rearrangement)
Then 8m^2 - 6m - 19 (you are not required to solve this)
Please choose another problem from your list and do and share all you can about your efforts to solve it.
Answer:
4x^2 - 1 = 0
Step-by-step explanation:
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
4x^2 - 1 = 0
