I've uploaded a photo with the answer because it's too hard to do this out on the computer.
Answer:
Since he rode 9/10 to the store and 4/10 to his uncles house now, total distance covered is
9/10+4/10=13/10miles or 1.3miles
Step-by-step explanation:
First you find the total distance he rode by adding both distance he traveled then devide.
4x + 9 - (10/(3x)) I favored the x^2 then expanded and simplified each rational term
In a Geometric Sequence,<span> each term is found by </span>multiplying<span> the previous term by a </span>constant<span>. For this case, the constant is 4. To find the sum of the geometric sequence with 8 terms, we use the formula as follows:
</span>∑(ar^k) = a ( 1-r^n) / (1-r)
<span>
where a is the first term, r is the constant, n is the number of terms
</span>∑(ar^k) = 4 ( 1-4^8) / (1-4)
∑(ar^k) = 87380
