Answer:
D 75 inches, 55 inches, 45 inches
Step-by-step explanation:
The sum of the two shortest sides must exceed the length of the longest side. This is only the case for choice D.
A. 45+55 < 110
B. 45+45 = 90 . . . . needs to be greater, not equal
C. 35+45 < 100
D. 45+55 > 75 . . . . will form an obtuse triangle
You subtract the number (5) on the other side of the = sign from the number on the side of the = sign. and divide (-5a) by the number you subtracted before. So untimely- 5-5= 0 ÷ -5a = 0
6 1/3- 4 2/3 =5 4/3- 4 2/3=1 2/3
You can't subtract fractions unless you have the same denominator.
Answer: To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations.
