Consider the equation.
babunello [35]

Answer:

If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?

You would subtract 5/7 from both sides of the equation

What is the solution?

x = 26/7 or 3 and 5/7

Step-by-step explanation:

x + 5/7 = 31/7

Subtract 5/7 from both sides of the equation:

x + 5/7 - 5/7 = 31/7 - 5/7

x = 26/7

aivan3 [116]
For the answer to the question above asking to p<span>rove the Pythagorean Theorem using similar triangles. The Pythagorean Theorem states that in a right triangle, 
</span>A right triangle consists of two sides called the legs and one side called the hypotenuse (c²) . The hypotenuse (c²)<span> is the longest side and is opposite the right angle.

</span>⇒ α² + β² = c² 
<span>
"</span>In any right triangle ( 90° angle) <span>, the sum of the squared lengths of the two legs is equal to the squared length of the hypotenuse."
</span>
For example:  Find the length of the hypotenuse of a right triangle if the lengths of the other two sides are 3 inches and 4 inches.  
c2 = a2+ b2
c2  = 32+ 42
c2 = 9+16
c2 = 15
c = sqrt25
c=5

Find the perimeter of the figure.
astraxan [27]

Answer:

26 meters

Step-by-step explanation: Ez. First add all the data you already have. You should end up with 19. Then, you want to find the length of the missing side. Well, we know it's 7 meters since its opposite is 7, and these lengths are in the same square. So 19+7 is 26 meters.

IM STCK PLZ HELP!!! THANK YOU :)
lesya [120]

Answer:

x = 81, y = 68 and z = 99

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle, thus

z = 63 + 36 = 99

x and z form a straight angle and are supplementary, so

x + z = 180, that is

x + 99 = 180 ( subtract 99 from both sides )

x = 81

The sum of the 3 angles in a triangle = 180°, thus

z + y + 13 = 180, that is

99 + y + 13 = 180

112 + y = 180 ( subtract 112 from both sides )

y = 68
