Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
Answer:
x=9
Step-by-step explanation:
5( x + 7) - 3 ( x - 4) = 7x + 2
Distribute
5x+35 - 3x +12 = 7x +2
2x +47 = 7x+2
Subtract 2x from each side
2x+47-2x =7x -2x+2
47 = 5x+2
Subtract 2 from each side
47-2= 5x+2-2
45= 5x
Divide by 5
45/5 =5x/5
9 =x
Answer: The line starts at 1 positive, then from there go -4 (so go to the left) then 1 down from that point.
Step-by-step explanation: the problem is supposed to have been Y= -4/1 +1
To solve this problem, all we have to do is to closely
analyze the situation. Now we are given that the amount of saving per week is
equivalent to one fifth (1 / 5) of Ben’s weekly pay (or weekly salary).
Now we are to find the weekly pay or weekly salary that
result in weekly savings of $61.50. So we can see that actually the value of
61.50 is one fifth (1 / 5) of W, therefore:
(1/ 5) W = 61.50
W = 5 * 61.50
W = $307.5
<span>Therefore a weekly pay of $307.5 will result in a weekly
savings of $61.50</span>
