Answer:
can someone please translate it to english?
Let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
Answer:
x<5
Step-by-step explanation:
233.09+49.14+29.13=311.36
600-311.36=288.64
x<288.64
288.64/52.48=5.5
We'll round to the lesser number since we can't assume greater
x<5
Answer:
Step-by-step explanation:
He bought a total of 5 tickets, some child, some adult. This is the NUMBER equation.
# of adult tickets + # of child tickets = 5 tickets
Now for the COST equation. Each child ticket costs $2, so the expression for that is 2c; each adult ticket costs $8, so the expression for that is 8a. He spend a total of $22:
$2c + $8a = $22
Money and the number of tickets are NOT THE SAME so they cannot be put into the same equation. They won't add or subtract because they're not like.
Your system is choice A
