Answer: D
Step-by-step explanation:
A. 3 + -7 < -4
-4 < -4
X
this one isn’t a solution
B. 3 + -7 ≤ -4
-4 ≤ -4
this works, let’s try the other equation
3(3) + 2(-7) < -5
9 + -14 < -5
-5 < -5
X
this one doesn’t work either, let’s go on to the next one
C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math
D. we know the first equation works because we did it in B
let’s go on to the second equation
3(3) + 2(-7) ≤ -5
9 -14 ≤ -5
-5 ≤ -5
this works, so that means that both equations work and the whole thing works :)
The last statement is true
First step is to do distributive property.
so you multiply 5 by -3.4k and -7
your equation now is -17k-35+(3k+21)
Then you add like terms
add -17k+3k to give you -14k-35+21
then you add like terms again
add -35+21 to give you -14
so now your equation is -14k-14
So that is your answer simplified
