Answer:
10 + (-14) = -4
Step-by-step explanation:
Given that,
Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.
For addition, she will add 10 and (-14) as follows :
10 + (-14) = -4
So, the crrect option is (b) "10 + (-14) = -4".
♥ Lets do this: X is 20% of 145
♥ Now our equation will look like this <span>x = 20% * 145
♥ </span>Converting percent to decimal:
♥ X = 20%/100 = 0.2
<span>♥ X = 0.2 * 14
♥ </span><span>X = 29
♥ Therefore 29 is 20% or 145
♥Hope this helps♥</span>
Answer:
0=0
infinitely many solutions
Step-by-step explanation:
plug x=2y+3 as x into 3x-6y=9...so
3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals
if you solve its
6y+9-6y=9
0y=0
y=0
making it 0=0

Answer:
c. quarterly
Step-by-step explanation:
To start with 1 year is equal to twelve months
3months out of 12 months will be;
3/12= 1/4
Here it is compounded quarterly and n=4 where n is the number of compoundings a year.
Lets study the compound interest formula;
where;
A=The ending amount
P=Starting amount
r=rate of interest expressed as a decimal
n=number of compoundings a year
t=total number of years
The number of compoundings in any one year can be an interest compounded yearly where n=1, semi-annually with n=2, quarterly where n=4, monthly where n=12, weekly and n=52 and finaly daily with n=365.
