What equation represents the statement below 80% of what number is 64

Answers

Answer 1

Answer: let the number be x

x/10 x 8 = 64
x/10 = 64/8 = 8
x = 8 x 10 = 80
so the number is 8

Which expressions show how 6 • 45 can be rewritten using the distributive property?A: 6×40+×5
B: 6×40-6×5
C: 6×50-6×5
D: 6×50+5

Answers

distributive property is
a(b+c)=ab+ac
a(b-c)=ab-ac

45=40+5 and 50-5 therfor

40+5=45
6*45=6(40+5)=6(40)+6(5) option A

also
50-5=45 so
6*45=6(50-5)=6(50)-6(5) option C

answer is A and C

Your answer is A because if you see, (6x40) is equal to 240 and (6x5) is equal to 30 and if you add them you'll get 270 and (6x45) is equal to 270...

Dont know lol it is something I am not familiar with ask your teacher

Joelle bought 20 lollipops and 6 bags of Doritos for a total cost of $8.20. She knows that each lollipop cost 25 cents and reasoned that two bags of chip must cost a little more than $1.00. Is this a reasonable guess? Why or why not?

Answers

I mean... I think it's a reasonable guess because not gonna lie- chips can get expensive. BUT- It doesn't really make sense because like, she bought so many lollipops. My brain isn't really functioning to do the math- but my best guess would beeeee...UNreasonble. I'm super super sorry if it's wrong. Math isn't my strong point, sorry. Have a nice day!

Answer:

Step-by-step explanation:

because 20×.25 = 5 so the lollipop cost $5.00 and then you only have 3.20 left over
