What is the estimated difference of 12 9/11 - 8 13/15

tekilochka [14]

Answer:

the estimated difference is 4

Step-by-step explanation:

The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number

12 9/11 becomes 12 11/11 which is 13

8 13/15 becomes 8 15/15 which is 9

we rounded each fraction up since each fraction was above the half way mark so the new equation is,

13 - 9 = 4

Answer:

135°

Step-by-step explanation:

That triangle in the corner is an right angle isosceles triangle as that line the midpoint of both sides :

the base angle of this triangle (x) will be :

180 = 90 + 2x

90 = 2x

x= 45

Angles on a straight line add up to 180. So to work out a :

180 = 45 + a

135 = a

bezimeni [28]

Answer:

Step-by-step explanation:

Since the x coordinate is -1, 2+t = -1, and thus t = -3.

So, y = 1+(3/(-3)) = 0.
