Answer:
I think x = 44°
Step-by-step explanation:
Finding the exterior angle:
180° - 45° = 135°
We know that x is multiplied by 3 (3x) so we divide 135 by 3.
135° / 3 = 45°
We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.
Trying a few possible answers:
43° × 3 = 129°
129° + 3° = 132°
That one wasn't quite right.
44° × 3 = 132°
132° + 3° = 135°

-2.5(1-2n)-1.5n
=-2.5+5n-1.5n
=-2.5+3.5n
Answer: B. -2.5+3.5n
<span>The answer is that the fraction of 1/2 pint is 1 cup. To solve this you must know the equivalence between pints and cups, and use the notion of proportions. Two cups equal one pint. Then you can state this proportion: 1 pint / 2 cups = x pint / 1 cup. When you solve for x you get: x = 1/2. Which means that 1 cup is 1/2 of 1 pint. </span>
