AfilCa [17]3 years ago
6 0

Answer:

11

Step-by-step explanation:

m∠1  = m∠2  {Corresponding angles}

78 - 2x = 89 - 3x

Add 3x to both sides

78 - 2x + 3x = 89

78 + x = 89

Subtract 78 from  both sides

x = 89 - 78

x = 11

Which lists show numbers ordered from least to greatest? Choose all that apply.
saw5 [17]
The answer is C. -<span>3 3/4, -2 1/4, 1 1/8 

It is because the highest number in the negatives, -3 3/4, is always the lowest. Obviously if there is no negative sign it is positive. 1 1/8 is the only positive so it is the greatest. And -2 1/4 is lower that -3 3/4. So it is higher than -3 3/4 but lower than 1 1/8.

I'm sorry I'm not the best explainer, but does this help?</span>
