Mathematics

JulijaS [17]3 years ago
8 0

<em>Note: I am assuming you meant to write the value of y = 12 instead of w = 12. </em>

<em>So, I am assuming y = 12</em>

Answer:

The value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

Step-by-step explanation:

Given the expression

13\:-\:0.75y\:+\:8x

Given

  • y = 12
  • x = 1/2

substituting y = 12 and x = 1/2 in the expresion

13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)

                            =13-0.75\cdot \:12+8\cdot \frac{1}{2}

                             =13-9+4

                             =8

Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

angle A + (38 more than angle a) = are complementary
2A = 52
A = 26
