Let f=amount invested at 4% and e=amount invested at 8%
0.04f+.08e=800
However, e=2f so the above equation becomes:
0.04f+0.08(2f)=800
0.04f+0.16f=800
0.2f=800
f=$4000, since e=2f
e=$8000
So Susan invested $4000 at 4% and $8000 at 8%.
Answer: it will be 3 feet high
Step-by-step explanation: what you do is read what it is asking you again and the answer is 3
Easy ! you first subtract the 5 to itself and to the 17, so 5 - 5 and 17 - 5. your equation should look like 3g = 12. since we need to isolate the variable (g) we need to divide 3 by itself and 12 by 3, so 3 ÷ 3 and 12 ÷ 3. now you have g = 4!
