Answer:
It is a linear equation because it is a straight line.
Step-by-step explanation:
Percy probably made his estimate by rounding 0.58 per pound to 0.50, and rounding 2.03 for the price to 2.00. The 2.00/(0.50/lb) = 4 lb.
Percy's estimate is not unreasonable, but it is somewhat high (by more than 10%).
The cost, 0.58/lb, is closer to 0.6, a number that would cause Percy to estimate his purchase at 20/6 = 3 1/3 pounds.
When estimating, it is often useful to make an estimate of the error. This last estimate will be a little low, by about 3% due to the estimated cost and 1.5% due to the estimated total amount paid, for a total of about 4.5% low.
Answer:
The non-equivalent ratio is 4:5.
Step-by-step explanation:
2/3 4/6 and 8/12 are equivalent because they are all multiples of each other.
Answer:
-3

Answer:
The value of the exterior angle is ![104\°](https://tex.z-dn.net/?f=104%5C%C2%B0)
Step-by-step explanation:
we know that
The sum of the interior angle plus the exterior angle is equal to
, because are supplementary angles.
Let
x-----> the measure of the exterior angle
so
![76\°+x=180\°](https://tex.z-dn.net/?f=76%5C%C2%B0%2Bx%3D180%5C%C2%B0)
solve for x
![x=180\°-76\°=104\°](https://tex.z-dn.net/?f=x%3D180%5C%C2%B0-76%5C%C2%B0%3D104%5C%C2%B0)
