Hi there,
I believe there are 3 questions.
- 2+5=8-1 It is true because 2+5 is 7 and 8-1 is 7. So, both sides have same value which means they are equal.
- 4+2=9-1 It is false because 4+2 is 6 and 9-1 is 8. So, the values are different.
- 13-0=12+1 It is true because 13-0 is 13 and 12+1 is 13. Both values are same. Therefore, they are equal.
Hope it helps :-)
Given the system of the equation below;

We can use the elimination method to solve the systems of equations
Step 1: Subtract equation 2 from equation 1 and solve for x

Step 2: Sustitute x = 1 in equation 1

Therefore, the solution to the system of equation is
Answer:
0.800 kg
Step-by-step explanation:
The midpoint divided a segment into two congruent lengths/segments.
So, QM = MR.
Set up the equation.
16 + x = 2(x+ 2)
16 + x = 2x + 4
12 + x = 2x
12 = x
Now, that you have the value of x, substitute it for the two equations.
QM = 16 + x
QM = 16 + 12
QM = 28
MR = 2(12+ 2)
MR = 2(14)
MR = 28
Find the whole length by of the line by adding the two segments. 28 × 2 = 56.
QR = 56
