Answer:
The two numbers are 13 and 6.
Step-by-step explanation:
x+y=19
x-y=7
-----------
2x=26
x=26/2
x=13
13+y=19
y=19-13
y=6
x=13, y=6.

Answer:
assuming youre asking for line of symmetry, it's a line that cuts a shape exactly in half.
for example, a square has 4 lines of symmetry
We can set up a system of equations:
x + y = 12
x - y = 4
Adding these two together:
2x = 16
x = 8
Substituting 8 in the first equation:
8 + y = 12
y = 4
Hope this helps!
Answer:
He will have to pay $192 in simple interest.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
E = P*I*t
In which E is the interest, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:
P = 600, r = 0.08, t = 4
So
E = P*I*t = 600*0.08*4 = 192
He will have to pay $192 in simple interest.
