Answer:
19°
Step-by-step explanation:
19° + 24° + x = 180°
43° + x = 180°
x = 137°
24° + 137° + f = 180°
161° + f = 180°
f = 19°
(8+5)- 2
First, add 8+5 (=13)
Then, subtract 2 (=11)
So the answer is 11
Can you make it more clear so I can comment the answer?
Answer:
Step-by-step explanation:
2x + 3y = 13 ------------(i)
4x -y = -2 ----------------(ii)
(i) 2x + 3y = 13
(ii)*3 <u> 12x - 3y = -6 </u> {multiply(ii) by 3}
add, 14x = 7
x = 7/14 = 1/2 = 0.5
x = 0.5
Put x = 0.5 in (i)
2*0.5 + 3y = 13
1 + 3 y = 13
3y = 13-1
3y = 12
y = 12/3
y= 4
