Answer:
x = 2 ; y =1
Step-by-step explanation:
6x-2y=10 -----------------(i)
6x+3y=15 -------------(ii)
multiply (i) by (-1)
(i)* (-1) -6x + 2y = -10
(ii) <u> 6x + 3y = 15</u>
add, 5y = 5
y= 5/5
y = 1
Put y = 1 in (i)
6x - 2*1 = 10
6x - 2 = 10
6x = 10 + 2
6x = 12
x = 12/6
x = 2
The mode of a set of data is the number that appears the most. We'll set it up from least to greatest to figure this out efficiently.
31, 31, 39, 52, 87.
31 appeared more than any other number, so 31 is the mode.
Answer:
- City A was the warmest
- City B was the coolest
Step-by-step explanation:
If we list the temperatures from lowest to highest, they are 58, 60, 64, 68. The highest temperature was the warmest. It was recorded in City A.
The lowest temperature was the coolest. It was recorded in city B.
City A was the warmest; city B was the coolest.
2x+12=3x-31. we add 31 to both sides 2x+33=3x. we subtract 2x on both sides and get 33=x so x is 33
