Answer:

Step-by-step explanation:

Angle of a straight line = 180 degrees :)

So to find x you would do:

x = 180 - 118 = 62

Also the angle sum of a triangle = 180 degrees.

Since it is an isosceles triangle, the bottom two angles would be equal:

Angle sum of triangle = 180

x + x + y = 180

Since we know x = 62, substitute it into the above equation:

62 + 62 + y = 180

124 + y = 180

Subtract 124 from both sides to solve for y.

y = 180 - 124

y = 56

Mike and his dad are retiling his bathroom floor. They have budgeted $200 for the tiles and supplies. The tiles cost $1.85 each

Feliz [49]

Answer:

Equation: $114.90 + $1.85<em>x</em> = 200

Solution: They can buy 46 tiles.

Step-by-step explanation:

First, subtract 114.90 from both sides to get 1.85<em>x</em> = 85.10.

Divide 85.10 by 1.85 to get 46, which is the answer.

If a = 5^x, b = 5^y and a^y×b^x = 25 then prove that: xy =1

avanturin [10]

$a = {5}^{x} \\ b = {5}^{y} \\ {a}^{y} \times {b}^{y} = 25 \\ prove \: ( {5}^{x} )^{y} \times ( {5}^{y} ) ^{x} = 25 \\ {5}^{xy} \times {5}^{yx} = {5}^{2} \\ {5 }^{xy + yx} = 5^{2} \\ 5^{2xy} = {5}^{2} \\ is \: \: 2xy = 2 \\ xy = \frac{2}{2} \\ xy = 1$
