It is C. In option C, it tells you that x=4. All you have to do is fill in the blanks.
7 • 4 - 11 = 17
28 - 11 = 17
17 = 17
The statement is true. 17 does equal 17, so the answer is C.
A(n)=-10 + (n-1)4
a(n)= 10 + 4n -4
a(n)=4n+6
The equation that this is representing is 2(n+2)=3(n-9)
so 2n+4=3n-27
and n=31
so the final answer is 31
If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.
