Answer:
140,120
Step-by-step explanation:
sum of angles in a quadrilateral =360
sum of the 1st two angles=60+40=100
360-100=260
the ratio of the remaining angles 7:6
therefore:

=140
for the second angle
260-140=120
Answer:
False
Step-by-step explanation:
Because it not possible
Answer:
-12x+29
Step-by-step explanation:
= -2(x+3) – 5(2x – 7)
= -2(x)+(-2)(3)-5(2x)-5(-7)
= -2x-6-10x+35
= -2x-10x-6+35
= -12x+29
Answer:
3
+9x-30
Step-by-step explanation:
Multiply the three into each number
3
+9x-30
Answer:
Step-by-step explanation:
-5x + 35 = 40
Subract 35 from both sides -5x + 35 - 35 = 40 - 35 = (-5x = 5)
Divide -5 from both sides -5x / -5 = 5 / -5 =
x = -1
