I think it's 12x.
I'm not a 100% sure though, but I hope this helps. =^D
Answer:
z=16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(z−6)=−70
(−7)(z)+(−7)(−6)=−70(Distribute)
−7z+42=−70
Step 2: Subtract 42 from both sides.
−7z+42−42=−70−42
−7z=−112
Step 3: Divide both sides by -7.
−7z
/−7
=
−112
/−7
z=16
Step-by-step explanation:
I think the answer for the 3) is S=(a×ha)÷2= (7×4.2)÷2= 29,4 ÷2=14.7
And for the 5) one im really not sure.
Her error was that she misplaced the numbers
-30x ≥ -300
its supose
to be -30x ≥ 200
Answer:
Inverse
Step-by-step explanation:
Assuming that c is a constant (the constant of proportion), s = c / (t^3) is a case of inverse variation: As t increases, s decreases.
Hope this helps <3
