Answer:
x = -11 5/17
Step-by-step explanation:
3x + 2y = 12
2x - 3y = -57
5x + y = -45
y = -5x - 45
2x - 3 (-5x - 45) = -57
2x + 15x + 135 = -57
17x + 135 = -57
17x = -192
x = -11 5/17
Answer:
Step-by-step explanation:
If the ratio of triangle = 3:4:2
Total ratio = 3+4+2 = 9
The sum of angle in a triangle is 180°
1st angle= 3/9 × 180 = 2 × 20 = 60°
2nd angle= 4/9 × 180 = 4 × 20 = 80°
3rd angle= 2/9 × 180 = 2 × 20 = 40°
Answer:
C = 36°, 57°, 87°
Step-by-step explanation:
scalene = all angles are different.
acute = all angles are under 90°.
triangle = all angles add up to 180°.
The only option that works for this is C) 36°, 57°, 87°
Answer is: add 4 in between every time
Explanation:
in 45 and 49 there is difference of 4
and in the next 61 and 69 the difference is 8
every it adds 4
i hope you get the idea
Answer:
Step-by-step explanation:
You are going to go below zero with this one and in oF that's going to be mighty cold.
61- 74 = - 13 degrees.
I lived in a place where, during winter, - 20 was consider time to start growing tropical fruit. So - 13 is not so very bad if you are used to it.
