Ms. Owens has some pencils . She give 5 of them away. Now she has 13 pencils left. How many pencils did she start with? I need a Equation with unknown

18

Step-by-step explanation:

x-5=13

You could also add 13 and 5 for a short answer

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

11

step-by-step explanation:

32.50-7.50=25

225/25=11
