Answer:
Step-by-step explanation:
We have:
To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:
Divide both sides by 2:
Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:
Therefore, our solutions are:
-- 137% means 1.37.
-- "of" means "times".
1.37 x 720 = exactly <em>986.4 .</em>
The next greater hundredth is 986.41 .
The next smaller hundredth is 986.39 .
Neither of those is nearer to 986.4 than 986.4 already is,
so no rounding is necessary..
