Solve for x ???????????

Mathematics
1 answer:

Do you recognize that the hypotenuse here has the length 22 and that the opposite side is the unknown (x)?  The angle is 21 degrees.

This is a perfect application of the tangent function:

tan 21 deg = opp / adj = opp / 22 = x / 22

tan 21 deg = 0.384                             so x would be 22 tan 21 deg, or
                                                                x = 22*(0.384)
                                                                   = 8.45  (answer)

What is the solution set for the open sentence with the given replacement set? 4y + 2 = 18, {4, 5, 6, 7}
4vir4ik [10]
+2 crosses the equal sign to become 4y=18-2,as 18-2=16 so you get 4y=16 and finally divide both sides by 4,as 4 goes into 16,4 times,therefore,y=4

5x−4 = 3x +8<br> i need the steps on how to find x<br> plz, i got a 0 the first time i did it
svetoff [14.1K]

Answer:

5x − 4 = 3x + 8

5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>

5x = 3x + 12

5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>

2x = 12

2x <em>/ 2</em> = 12 <em>/ 2</em>

x = 6

The answer for the first one would be 4 just divide both 16 & 4.

The answer for the second one would be -7 just divide both 63 & -9.

The answer for the third one would be -36 just multiply both 12 and -3.

The answer for the fourth one would be -120 just multiply -10 and 12.
