The scale can translate just by division if we get it down to what 1 cm equals. 1 cm=3 km, so with this given information you can find:
A)
3 Cm=9 Km
B)
1=3, times both sides by 5 that is 5 Cm= 15 Km
A) x+5=13 -- subtract 5 from both sides
x=8
B) -6x=-30 -- they're both negative so change the sign to positive
6x=30 -- divide both sides by 6
x=5
C) x/4=18 -- multiply both sides by 4
x=72
D) x-2=-11 -- add 2 to both sides
x=-9
D gives the lowest answer.
Answer:
−
9
x
2
−
12
x
Step-by-step explanation:
That might look a little confusing so let me explain it
-9x^2.
X is raised to the 2nd power
-12x
This stays the same
Glad I could help!!
First differences are -9, +18, -8, +16, suggesting that the next ones will be -7, +14.
Hence, the next two terms might be expected to be 13, 27.
