Answer:
2 + (-6) ÷ 4 ⋅ 4
Step-by-step explanation:
Given in the question an expression,
2 + (3 - 9) ÷ 4 ⋅ 4
First step to solve this problem is to solve the arithmetic which is inside the brackets.
<h3>= 2 + (-6) ÷ 4 ⋅ 4</h3><h3>= 2 - 6 ÷ 4 . 4 </h3>
Anything in parentheses always come first when solving a problem.
Answer:
A. x = -3/10 , y = 69/20
B. x = 1/2 , y = 5/2
Step-by-step explanation:
A]
3x + 2y = 6......eq1
13x + 2y = 3.......eq2
From eq 2 - eq 1
10x = -3
x = -3/10
So,
3x + 2y = 6
3(-3/10) + 2y = 6
y = 69/20
B]
6x+2y = 8.....eq1
3x - y = -2.....eq2
eq2 x 2 and add in 1
12x = 6
x = 1/2
So,
6x+2y = 8
y = 5/2
Answer:
217°
Step-by-step explanation:
the tangent ratio is positive in the first and third quadrants.
37° is the angle in the first quadrant
then the angle in the third quadrant is
180° + 37° = 217°
