Answer:
on the second equation, the answer for (4 - 17) should be -13, not just 13.
On the 3rd equation, she forgot to put x next to the 8.
correct answer is 1/2
There are a couples of ways to find the solution to the system of equations:
1. If the equations are provided we can use method of substitution or we can use method of elimination to find the solution to the system of equations.
2. Another method to find the solution to the system of equation is by graphing.
Now, when we graph a system of equations, the point of intersection of the two graphs tell us the solution to the system of equations.
Here as we can see that a pair of equations are plotted already and they intersect at point
, where
and
.
Therefore, the solution to the system of equations is
(that is the point of intersection as well).
Answer:
3.6
Step-by-step explanation:
After the decimal point to the right, the first number is the 'tenths' spot. That number is the one they're asking you to round. As we know, when rounding, the number is rounded up if it is 5 or more. Since the number in the 'hundreths' spot is above 5, the 'tenths' spot is rounded up, making 5 a 6.
So, the answer is 3.6
