To figure out R, add 1.97+0.65 together. 1.97+.065=2.62
first multiply the outside numbers by both the numbers in the ()
10xg=10g 10x5=50 2xg=2g 2x9=18
then combine like terms
10g+50=2g+18
8g=32
then divide
g=4
Answer:.66
Step-by-step explanation:
You divide 8 and 12
63x+45x = 108x
You just multiply 3x by 21 and 15 to get 63x and 45x. You then add the like terms to get 108x.
