I=PRT
Interest=I
P=principal
R=rate in decimal
T=time in years
given
asuming 640 is the principal and not the interest
P=640
R=3%=0.03
T=2
I=640*0.03*2
I=19.2*2
I=38.4
interst=$38.40
Hi there! The formula for finding slope is y2 - y1/ x2 - x1. -4 represents x2, and 2 represents x1. -4 - 2 is -6. If you think about it, 3/-6 makes -1/2. -3 is y1, so we will be adding, because adding a negative number actually means adding. 0 - (-3) gives us 3. There. The value of r is 0.
Okay. so AC is like AC= AB which is an angle
Malachy- $9
Gavin- $3
Gavyn- $6
Solution;
Add up all the numbers in the ratios. So 3+1+2 is 6. Now do the money ($18) divided by the tattled up ratio (6). 18 divided by 6 is $3 which is now equal to 1. Now for malachy you do his ratio (3) times our number equal to one of those ratios (3). 3 times by 3 is $9. Same for others. 1 times 3 is 3. 2 times 3 is 6.
