Answer:

A = 70

Step-by-step explanation:

CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.

Find the slope of the line. 5x – 2y = 7

nika2105 [10]

Answer:

Final answer is slope $m=\frac{5}{2}$

Step-by-step explanation:

Given equation is $5x-2y=7$

Now question says to find the slope.

Since given equation $5x-2y=7$ is a linear equation so we need to compare $5x-2y=7$ with slope intercept formula $y=mx+b$ to get the value of slope m.
