you don't have enough info, we need to know how old he was when he was twice her age, or how old she was
Answer:
160 dollars
Step-by-step explanation:
So you would add 6.19 and 9.81 together. Then divide it by 2. You would get 8. Then multiply it by 20 and you would get 160 dollars
For section 3.01 black, number 1 is correct, but number 2 is wrong.
When you raise an exponent to an exponent, you multiply the 2 exponents.
(x^4)^5 is x^20.
Number 3 is also right.
For 3.02, you use the interest formula. (1 + i/100)^t times x
x is the amount of money you have originally. i is the interest rate, t is the time.
1,500(1.03)^5 = 1738.91111145
$1738.91
For section 3.01 red in fractional exponents the numerator are the powers and the denominator is the root.
![\sqrt[4]{a^{3} } = a^{\frac{3}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Ba%5E%7B3%7D%20%7D%20%20%3D%20a%5E%7B%5Cfrac%7B3%7D%7B4%7D%20%7D)
In order to do that we would need to see the list of potential answers.
