B.) 23
the equation set up is “ 4x+13=105 “
do -13 on both sides which would then leave you with “ 4x=92 “. then you just divide 4x on both sides, giving you the answer of 23 :D
Answer:
e = 54
f = 20
d = 106
Step-by-step explanation:
Opposite angles are the same. Also, straight lines always equal 180 degrees.
Hope that this helps!
Answer:
not sure
Step-by-step explanation:
Answer:
D. (2, -3/4)
Step-by-step explanation:
Using the substitution method:
-5x+4(1/8x-1)=-13
-5x+0.5x-4=-13
-4.5x/4.5=-9/4.5
-x=-2
x=2
You are supposed to replace 2 in the first equation now but as there is no other option with x value of 2 D is the answer.
If continued:
-5(2)+4y=-13
-10+4y=-13
4y=-3
y=-3/4
Answer: isosceles
Step-by-step explanation:
By the alternate interior angles theorem,
Since angles in a triangle add to 180 degrees,
Since sides opposite equal angles in a triangle are equal, .
So, triangle ABC is <u>isosceles</u>
