I thought you made it zero...
Like for this one, adding 10 on both sides.
-13 would become -3 and then you would use the Quadratic formula.
Though I may be wrong
That’s the same question I’m going to ask.
Answer:
<em><u>
</u></em>
Step-by-step explanation:
First add 10 to x which equals x +10
Now divide it by 4 you get <em><u>
</u></em>
1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand
cross multiply because this is a proportion
(1)(x) = (7.15)(1000)
x = 7150 <=== Sophia got 7150 rand
That means one ship requires 11 pirates.
