X+2,000=stocks
x=bonds
7.2%⇒(.072)(x)=bonds invested
6%⇒(.06)(x+2,000)=stocks invested
Here is the equation:
x(.072)=(.06)(x+2,000) | Since the income from both equal
You then solve each side first (assume you know how to but if not, let me know)
You first multily the parentheses/x variables
⇒.072x = .06x+2,000(.06)
⇒.072x = .06x+120
You then minus .06x from each side
⇒.012x = 120
You then divide each side by .012
.012x÷.012=x
120÷.012=10,000
x=10,000
Now change the original x variables with 10,000
.072($10,000)=$720 bond interest
<u>They are equal so $720×2=$1440</u>
Easy, you just replace m with 2, and when a letter is placed next to a number then it means you multiply them, therefore
6*2-1=12-1 = 11
2×4=8 because 2 and 4 would be the addends and their less than 5 and it equal an answer between 4 and 10
I think it's 45.... good luck I'm sorry you have to do math lol
The answer would be -6a^5
