You would do
51-5= 46
then you would divide
46/2= 23
so Susan is
23+5=28
Susan is 28 years old and her sister is 23
28+23=51
You would put in 12 for x since there are 12 months in a year. Then you would multiply 12 by 35, and add 70.
Answer: x=3
Step-by-step explanation:
3x + 5 = 14
Subtract 5 from both sides
3x=9
Divide both sides by 3 to get x alone
x=3
3.6 divided by 9= 0.4
