X+y = 12
x-y = 3
x = 3+y
Substitute it in 1st equation,
3+y+y=12
2y = 9
y = 4.5
Substitute it in 1st eq.,
x = 12-4.5 = 7.5
So, the two numbers are 7.5 & 4.5
Hope this helps!
Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
43.7 % is equivalent to 0.437 .
Answer:
D
Step-by-step explanation:
When somethin is decreasing you would subtract the percent it was decreasing by, by 1.
.024 - 1 = .976
Lets put these numbers in order
1,2,3,3,4,5,6,7,8,8,9
Q1 = 3
Q2 (median) = 5
Q3 = 8
the box starts at Q1 and ends at Q3....so left side is 3 and right side is 8
u r correct...it is A
