  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

5a - 10b = 45

<em>b</em> = 3

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Substitute in <em>b</em> [Equation]:                                                                                5a - 10(3) = 45
  2. Multiply:                                                                                                             5a - 30 = 45
  3. [Addition Property of Equality] Add 30 on both sides:                                  5a = 75
  4. [Division Property of Equality] Divide 5 on both sides:                                  a = 15

In a right triangle the lengths of the legs are a and b. Find the length of a hypotenuse, if: a=3, b=4;
prohojiy [21]

Answer:

The hypotenuse is 5

Step-by-step explanation:

We can use the Pythagorean theorem to find the hypotenuse of a right triangle

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

3^2 +4^2 =c^2

9+16=c^2

25=c^2

Take the square root of each side

sqrt(25) =sqrt(c^2)

5 = c
