9.2x-9<7
add 9 to both sides, 2x<16
divide both sides by 2, x<8
A.
10.n<5
-4n+11>-9 Subtract 11 from both sides
-4n>-20 then, divide both sides by -4
In these greather than less than equations, when you divide a negative by another negative, you must flip the sign
so that would be, n<5
D
Answer:
P’(-1, 1), I’ (1, 2), G’(1,0)
Step-by-step explanation:
In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)
Therefore the answer is 3mn (#3)
Answer:
a = 24*1/3
a =8
Step-by-step explanation:
We are using proportions to solve this problem by putting students over adults
students 3 24
--------------- = --------------- = -------------
adults 1 a
where a is the unknown number of adults
Using cross products
3a=24*1
Divide by 3
a = 24*1/3
a = 24/3
a = 8
