Answer:
p= 21
Explanation:
FIRST DO
3(21) -7
3 × 21 = 63
63 - 7 = 56
THEN DO
6(21) - 2
6 × 21 = 126
126 - 2 = 124
FINALLY
It needs to add up to 180°
124 + 56 = 180°
Therefore, the value of p = 21
Hope this helps!!! :)
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
.48 is equal to 48/100=12/25 so
28 12/25
