Anna found the difference between thirteen and the product of four and a number. Which expression represents this phrase, and wh
at is its value if n = 3? StartFraction n Over 4 EndFraction minus 13; when n = 3 the value is Negative 12 and one-fourth
13 minus 4 n; when n = 3 the value is 1
4 n minus 13; when n = 3 the value is –1
13 minus StartFraction n Over 4 EndFraction; when n = 3 the value is 12 and one-fourth
The sum of the angles <6 and <3 must be 180. Since <3 and <1 are opposed to the top, their measure are equal. We need then to calculate the measure of angle >3 = 180 - <6 = 180-85=95
