5.
-4n+ 7+ 2n= 1
⇒ (-4n+ 2n)+ 7= 1 (combine like terms)
⇒ -2n= 1-7
⇒ -2n= -6
⇒ n= -6/(-2)
⇒ n= 3
Final answer: B. 3~
6. 4(y-4)= 8
⇒ y-4= 8/4
⇒ y-4= 2
⇒ y= 2+4
⇒ y= 6
Final answer: D. 6~
Well, we know that 1 hour is 60 minutes which means 2 hours is 120.
so to find the answer we turn 40% into a decimal which would be .40
Take .40 and multiply that by 120.
.40 * 120 is 48
40% of 2 hours is 48 minutes.
Hope this helps!
5 - 8x < 2x + 3
5 - 8x < 2x + 3
<u>-3 - 3 </u> Step 1.
2 - 8x < 2x
<u> +8x +8x </u> Step 2. Missing step
2 < 10x
<u>÷10 ÷10</u> Step 3.
<u>2/10 < x</u>
<u>1/5 < x
The missing step is add 8x to both sides of the inequality.</u>
