Answer:
the value of -6 is -6
Step-by-step explanation:
You flip is when you mulitply the whole equation by a negative
not when you distribute a negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3
but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x
because they will be differente
exaple
12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true
anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole
The ratio of width to length in simplest form is 19 : 44
<em><u>Solution:</u></em>
Given that, A cell phone is 132 mm long and 57 mm wide
Length of cell phone = 132 mm
Width of cell phone = 57 mm
We have to find the ratio of width and length in simplest form
In ratio form, we know that,
Writing in ratio form, we get
Width : length = 19 : 44
Thus the ratio of width to length in simplest form is 19 : 44
Answer: 720ways, 24ways
Step-by-step explanation:
Given the seven letter words "SYSTEMS", if E is always occurring before M it means E and M will always be together therefore they letter 'EM' will be taken as an entity to five us 6letters i.e SYST(EM)S.
This can then be arranged in 6!ways
6! = 6×5×4×3×2×1 = 720ways
Similarly, if the E somewhere before the M and the three Ss grouped consecutively, this means E and M must always be together as well as the Ss to give (SSS)YT(EM).
This means that the letters in the bracket can be taken as an entity to give a total of 4 entities. This can them be arranged in 4! ways.
4! = 4×3×2×1
4! = 24ways
Answer:
1500
Step-by-step explanation:
Given that :
Total number of marbles held by Layala and Zahra = 2700
Ratio = 2 : 7
Layala's share of marbles : (2 / (2+7)) * 2700
= 2/9 * 2700
= 600
Zahra's share of marble : (7 / (2+ 7)) * 2700
= 7 / 9 * 2700
= 2100
Hence, Zahra must have given away (2100 - x) = 600
2100 - 600
= 1500 marbles, so that both Zahra and Layala have the same number of marbles
