To find out how much he makes per week, take the amount and divide it by the week.
1520/4=380.
He makes 380 per week.
The other 6 books can be arranged in 6 ways
= 6*5*4*3*2*1 = 720 ways answer
Answer:
x
= 5y/8
y=8x/5
Step-by-step explanation:
-3x+7y=5x+2y
7y-2y=5y
-3x+5y=5x
5x+3x=8x
5y=8x
Solution: The another way to show the Fuaad's solution is
.
Explanation:
It is given that the solution of an inequality is
.
It can be break in two parts
and
.
The inequality
means the values of x is greater than
and the inequality
means the value of x is greater that than 7.
When we combine both results we get
it means the value of x is greater than 7.
It can also represented by number line as shown in given figure.
The number line shows the values of x and red lines shows the solution of both inequalities
and
.
The common region shows the combination of both the possible inequalities, therefore the another way to show the Fuaad's solution is
.
