18 = 32/100 x ?
? = 18 x 100/32 = 50
<span>Equation (1) x + y = 200
Eauation (2) x = y - 40
x represents the distance from the original location to the firstt city
y represents the
distance from the first city to the second city.
Solution:
(1) x + y = 200
(2) x - y = - 40
----------------------
2x = 200 - 40
2x = 160
x = 160 / 2
x = 80
x + y = 200 => y = 200 - x = 200 - 80 = 120
Therefore the solution (x,y) is (80,120)
Answer: the pair of coordinates that represents the solution (in miles) to this system of
equations is (80, 120) </span>
Answer:
see explanation
Step-by-step explanation:
Solve the inequality
y - 2 < - 5 ( add 2 to both sides )
y < - 3
The number line going from - 8 to + 2
Since y is not equal to - 3 then an open circle at y = - 3
Since y is less than - 3 the shaded to the left of y = - 3
