Number 1 is -4/3/8 here u go
Answer: 
Step-by-step explanation:

Answer:
x=ym−4
Step-by-step explanation:
y=(4+x)m
Here we have one equation with three unknowns. This cannot be "solved". We can only express one variable in terms of the other two.
Let's isolate x.
Divide through by m
ym=4+x
x=ym−4
(I really hope this helps)
<span>The question aks us to determine which statement is always true about the angles in the figure. If angle A and B form a right angle, then C must be also a right angle, which is not correct. Also if A and C form a right angle, then angle B must be a right angle. So answers A and C are false. Also thet we know that the sum of the interior angles of the triangle is 180 degrees. A + B + C = 180 deg. ( or a straight angle ). Answer: B. Angle A, angle B, and angle C, form a straight angle. </span>
