Answer:
x=0
y=-21/7
Step-by-step explanation:
Let the two unknown be x and y
x+y=-7...(1)
x-y=14...(2)
From (1) make x the subject of formula
x=-7-y...(3)
Substitute (3) into (2)
-7-y-y=14
-7-2y=14
Add 7 to both sides
-2y=21
Add both sides by-2
y=-21/2
Substitute the value of y into (3)
x=-7-(-21/2)
x=-7+21/3
Lcm
x=-21+21/3
x=0/3
x=0

Answer:
20 PERCENT
Step-by-step explanation:
BECUASE 40 INTO 60 AND THAT MEAN WE PLUS 20
An inequality may be used to model the given situation. The phrase, "no more than" implies "less than or equal to". Therefore, the inequality is:
15 ≤ t / 5
Solving the inequality of t, we get:
t ≥ 75
This means that the number t is at least 75 (the phrase at least implies greater than or equal to)
Hope this helps!
