Answer:
D
Step-by-step explanation:
well the anser has to equal 9 if you solved the question correctly BUT the other questions have to equal 9 so the first one is like this
(3*2-2)+(5*2+5*-1)
= (6-2)+(5*2+5*-1)
= (4)+(5*2+5*-1)
= 4+(5*2+5*-1)
= 4+(10+5*-1)
= 4+(10+-5)
= 4+(10-5)
= 4+(5)
= 4+5
= 9
Now the answers A is not it because
8*2+5*-3
= 16+5*-3
= 16+-15
= 16-15
= 1
B isnt it because
8*2+5*-1
= 16+5*-1
= 16+-5
= 16-5
= 11
And C isnt it because
2*2+5*-3
= 4+5*-3
= 4+-15
= 4-15
= -11
So that leaves D and this is how it is correct
= 8*2+7*-1
= 16+7*-1
= 16+-7
= 16-7
= 9
Hope this helps! Sorry I took so long
Answer:
4 blocks of cream cheese
Step-by-step explanation:
there are 16 Ounces in a pound.
You have 4 ounces of cream cheese. 4 is 25% of 16 so we subtract .25 from the required amount which is 2.25.
NOW we need 2 pounds. well, each block is 8 ounces, and we need in total 32 ounces. 32/8=4 blocks
2.5 MB + 4.1MB + 6.6 MB. 4914/6.6 = 744 total downloads. 744/5 = 148 standard downloads which leaves 595 high quality downloads. Therefore the answer is 148.
Answer:
part one:
6 3
22 1
30 0
part two:
0.50*s+4*a=15
Step-by-step explanation:
part one:
firstly:
6 individual songs cost 6*0.50= 3 dollars
she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together
it means that she has only 15-3=12 dollars to download full albums
so 12/4=3 albums
because 4 dollar cost one album and with 12 dollars she can buy just 3 albums
secondary:
she downloaded 1 album
and one album cost 1*4=4 dollars
she has 15 dollars ,after buying 1 album
she has 15-4=11 dollars
so she can download 11/0.50=22 individual songs
so she can download 22 individual songs.
the last one:
she downloaded 30 individual songs
that all together cost 30*0.50=15 dollars
but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.
because 15-15=0 money left
part two:equation
0.50*s+4*a=15
