Answer:

  76

Step-by-step explanation:

For age 'a', the special number was supposed to be ...

  2a +4

Tammi's mother actually calculated it as ...

  2(a +4) = 2a +8

a value that is (2a+8) -(2a+4) = 4 more than it was supposed to be.

The special number was supposed to be 80 -4 = 76.

Answer:

C

Step-by-step explanation:

y=mx+b is the equation for a line, where m is the slope.

For a line to be parallel to each other, they must share the same m value.

In your equation, y=6x+8, 6 is the slope

The only answer that shares that slope of 6 is C.

<em>I hope this helps! :)</em>

evablogger [386]

Answer:

y=124°

x=67°

Step-by-step explanation:

For the triangle on the right

180-74-50=56°

then y= 180-56=124°

For the triangle on the middle (that small triangle)

180-85(Head opposite angles)-50=45°

So

x=180-45-68=67°
