1. divide all sides by 24 to save time.
37=21-20x
2. subtract 21 this both sides
16= -20x
3. divide both sides by -20
-16/20 = x
4. reduce to its lowest terms
-4/5= x is the answer
So firstly let’s set a ‘algebra’
Let’s make the hours working after school as ‘x’
So Chase works totally 18 hours last week
So the hours he works on Saturday is (18-x)
And given the salary of working after school is $8 per hour,and the salary of working on Saturday is $10,and he earned $156
So with these we can write a equation
8x+10(18-x)=156
solve it,
8x+180-10x=156
-2x=-24
X=12
as I said x is the hour working after school
The hour working on Saturday should be 18-x
18-12=6
Answer is 6
Answer:
675
Step-by-step explanation:
This is going to be really hard for you to understand unless you know factorials.
The first four letters is a combination out of 6 letters; we call it 6 choose 4. As you may know, factorial is the multiplication of a number and it's previous digits. For example, 3! = 1 x 2 x 3
The 6 choose 4 is (6!/4!2!) = (5x6)/2 = 15
The 10 choose 2 is (10!/2!8!) = (9x10)/2 = 45
Then you multiply both as they're independent:
15 x 45 = 675 serial numbers
Answer:
x=2/3
Step-by-step explanation:
The mean is just the average of all the terms. Therefore, you can set up an algebraic expression to solve for x.
