Answer: Step E

Step-by-step explanation:

The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

Ten inches of snow is equivalent to about one inch of rain.1 Write an equation for the amount of precipitation, measured in inch

ipn [44]

<span>Since "s / 10" gives "r", "r" could be replaced by 0.1s. This would result in "f(s) = 0.1s" as a function linking the two. 0.1 multiplied by the number of inches of snow would result in the number of inches of rain.</span>

Can someone please help me with math

Answer:

$x = 71$

Step-by-step explanation:

The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.

Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.

$180 - 40 - 31 = 109$

So the missing angle is 109°. Now we can find the value of x.

We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.

$180 - 109 = 71$
