Answer:
A -9
Step-by-step explanation:
Let the number of girls=4x
then number of boys=7x
7x-4x=15
3x=15
x=15/3=5
boys=5*7=35
girls=4*5=20
number of students=35+20=55
Answer:
14) x = 0°
16 x = 2°
Step-by-step explanation:
14)
BJK = 146+2x
IJK = 172
IJB = 2x + 26
IJK = IJB + BJK
172 = 146 + 2x + 2x + 26
172 = 146 + 26 + 4x
172 = 172 + 4x
0 = 4x
x = 0°
16)
LMN = 135
LMV = -1 + 45x
VMN = 23x
LMN = LMV + VMN
135 = -1 + 45x + 23x
135 = -1 + 68x
136 = 68x
x = 2°
