If 30 pencils cost $15. How much does 45 pencils cost ? *

90

Step-by-step explanation:

30 divided 15 = 2

2 times 45 = 90

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.

0 is its x and y coordinate
