Answer:
m/_A=112°, m/_B=68°, m/_C=112°
Step-by-step explanation:
m/_A is 112° since consecutive /_s in a parallelogram are supplementary therefore 180°(<- supplementary sum)-68°(<- m/_D)=112°(<- m/_A, and m/_C), and in a parallelogram, one main property is opposite /_s are congruent therefore m/_B is congruent to m/_D so m/_B=68°.
Hopefully, this helps you out, have a great day!
Answer:
Look below.
Step-by-step explanation:
Our goal when solving a system of equations is to reduce two equations that have two variables, down to a single equation with one variable.
The original purchase price is 1126.91. Subtract 7.25 from 100 and multiply that answer by 12.15.
Answer:
x=6
y=-5
Step-by-step explanation:
3x+2y=8 equation 1
x-2y=16 equation 2
equation 2+equation1 ; 4x = 24
x = 6
substitution x in equation1 ;
18+2y=8
2y = -10
y = -5
