D. The x and y values are both negative
He would have to walk 175/3 minutes to burn off the ice cream. If you divide this by 20, you could find how many miles he would need to walk. 175/3/20 Which comes to roughly 2.9. If you round up, it is 3 miles. Please mark Brainliest!!!
Answer:
7.78
Step-by-step explanation:
6.5 x 1.88 = 12.22
20.00 - 12.22 = 7.78
Answer:
2a = 108
Step-by-step explanation:
the 3 angles of the triangle add to 180
lets call the unknown angle in the triangle y
a+10 + y + 44 = 180
we also know that 2a+ y = 180 because it makes a straight line
solve this for y by subtracting 2a from each side
2a +y = 180
y = 180 -2a
now we can substitute this into the triangle equation
a+10 + y + 44 = 180
a+10 + 180 -2a + 44 = 180
combine like terms
-a +234 = 180
subtract 234 from each side
-a = --54
divide each side by -1
a =54
the exterior angle is 2a
2* 54
108
