Answer:
(6,8)
Step-by-step explanation:
2x + y = 20
6x - 5y = -4
Multiply the first equation by -3
-3(2x + y) = -3*20
-6x -3y = -60
Add this to the second equation
-6x-3y = -60
6x - 5y = -4
--------------------
-8y = -64
Divide each side by -8
-8y/-8 = -64/-8
y = 8
Now find x
2x+y = 20
2x +8 = 20
2x+8-8 = 20-8
2x = 12
Divide by 2
2x/2 = 12/2
x = 6

Answer:
a) 11
c) 18
d) -25
Step-by-step explanation:
a)
Substitute: 3|-2| + 5|-1|
Absolute value is positive: 3(2)+5(1)
Simplify: 6+5
Simplify: 11
c)
Substitute: 4|-2| +8-(-2)
Absolute value is positive: 4(2)+8-(-2)
Simplify: 8+8+2
Simplify: 18
d)
Substitute: -3|-5|+2(-5)
Absolute value is positive: -3(5)+2(-5)
Simplify: -15-10
Simplify: -25
Answer:
B) -5 and 5
Step-by-step explanation:
Integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. One integer is negative and the other is positive.
