21 would be ur answer
69+21=90
Answer:
8.5
Step-by-step explanation:
When you go from negative to negative by going backwards you add positive.
The lowest number is - 3/2 or -1 1/2 as a mixed number (answer)
The we have greatest number which is 5/6 (answer) ( note there are 6 equal spaces between each integer value).
Difference between these numbers can be written as 5/6 - (-3/2)
= 5/6 - (-9/6) = 5/6 + 9/6
= 14/6
= 2 1/3 Answer
Also, difference = 5/6 - (-1 1/2)
= 5/6 + 1 + 1/2
= 5/6 + 6/6 + 3/6
= 14/6
= 2 1/3 (answer)
Gg easy
remember
for
ax^2+bx+c=0
first
minus c from both sides
ax^2+bx=-c
divide both sides by a (disregard if a=1)
take 1/2 of b and square it and add that to both sides
factor perfect square
ok so
x^2-3x=-1
-3/2=-1.5
(-1.5)^2=2.25
add that to both sides
x^2-3x+2.25=2.25-1
factor
(x-1.5)^2=1.25
