Answer:
C.) -7/5
Step-by-step explanation:
To subtract fractions, we need to have common denominators. So first, we will change -1 1/5 to -6/5.
Now we will change the denominator of both -6/5 and 1/2 to 10.
We now have:
5/10 and -12/10
5-12=-7
So the answer would be -7/5
If we want to use the number line, we would first find 5/10 (1/2) on the graph and count down (to simulate subtraction) 12 units since we are subtracting by 12. :))
3 (15-6)+(18-12)^2=
3 (9) + (6)^2=
27 + 36 =
63
It is used by turning it into a mixed number
Answer:
(2,4) is a solution to this system of equations
Step-by-step explanation:
Given system of equation are


To find the solution of the given system of equations
To Check that (2,4) is a solution to this system or not
Solving equations (1) and (2)
From equation (1) and y=2x
Now substitute y=2x is equation (2)






10-5x=0
-5x=-10

Substitute x=2 in equation (1)
y=2x
y=2(2)
Therefore y=4
Therefore the solution is (2,4)
Therefore (2,4) is a solution to the system of equations.
