Which operation is done first to evaluate this expression: 5 + 7 x 2 - 9

Multiply the 7 and the 2

7 x 2

Step-by-step explanation:

5 + 7 x 2 - 9

PEMDAS

P there are no parentheses

E  there are not exponents

MD  multiply and divide from left to right

5 + 7 x 2 - 9

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.
