39 degrees. All angles must add up to 180 and the two acute angles equal each other because of the type of triangle it is!
Answer:2.55 in fraction form is 51/20.
Step-by-step explanation:
Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7
1/3 1/3 1/6= 1+1=2/6 1/6=3/6 simply it to 1/2
