Answer:

3 AND 5

Step-by-step explanation:

LET THE TWO NUMBERS BE X AND Y

THEN

X + Y = 8 …….1

X – Y = 2 …… 2

WE SOLVE SIMULTANOUSLY  

SUBTRACTNG EQATION 2 FROM 1

X – X  + Y – (-Y) = 8 – 2

Y + Y = 6

2Y = 6

DIVIDING EACH TERM BY 2

2Y/2 = 6/2

Y = 3

THEN PUTTING Y = 3 IN EQUATION 1

X + 3 = 8

X = 8 – 3

X = 5

Julie is tracking the growth of a plant for a science project. The height of the plant on the 2nd day she measured was 8 inches
kvv77 [185]

Answer:

Step-by-step explanation:

The relationship is linear, so the plant grows the same amount each day.

The height on the 2nd day was 8 inches:

h₂ = 8

The height on the 7th day was 20.5 inches:

h₇ = h₂ + (7-2)d = 8 + 5d = 20.5

d = 2.5

The plant grows 2.5 inches each day.
