Answer:
960
Step-by-step explanation:
Over here, I'm going to do it in two ways, and either way works, one is just easier to do out:
1st way:
You can represent the percent 120 as a decimal which is 1.20, then you do 800*1.2.
2nd way:
You can use benchmark percents. You find 10 percent of 800 which is 80 and multiply 80 by 2 to get 160, so 20% is 160 dollars. Then you add 160 to 800 (800+160) and get 960.
Please tell me if you have any questions.

Answer:
t + 40 = 90
Step-by-step explanation:
90 minutes volunteering
40 minutes delivering flowers
90 - 40 = number of minutes answering phone (50 minutes)
so, t = 90 - 40 or rearranged to t + 40 = 90
Answer:
-2b(k²-3k+1)
Step-by-step explanation:
<u>The question is on factorization</u>
-2bk²+6bk-2b
<u>Factor out 2b</u>
-2b(k²-3k+1)
<u>When you open brackets to check the answer</u>
-2b×k²-2b×-3k-2b×1= -2bk²+6bk+2b
