-52 times the difference a number and 97 is equal to the number plus 39

VLD [36.1K]

-52 (x - 97) = x + 39

-52x + 5,044 = x + 39
+52x +52x

5,044 = 53x + 39
-39 - 39

5,005 = 53x

What is the length of side bc in the right triangle below

Fynjy0 [20]

Answer:

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for BC

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

BC² = AB² + AC² ← substitute values

BC² = 18² + 80² = 324 + 6400 = 6724 ( take the square root of both sides )

BC = $\sqrt{6724}$ = 82 → B

Find the difference.<br><br> (4−5y)−2(3.5y−8)

MAVERICK [17]

Answer:

-12y + 20

Step-by-step explanation:

First, you simplify each term:

apply the distributive property:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply 3.5 by -2:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply -2 by -8:

4 - 5y - 7y +16

Next, we simplify by adding terms:

Add 4 + 16:

-5y - 7y + 20

Subtract 7y from 5y:

-12y + 20

Hence the simplified form is -12y + 20
