Answer:
There should be 2 teachers and 21 students on each bus.
Step-by-step explanation:
The answer is x = 0, -13/2
Answer:
(a) The table of the ordered pairs is given as:
x-values 1 2 3 4 5 6
y-values 3 6 9 12 15 18
(b)
We find the equation from the table using the slope intercept form.
Let y=mx+c
on using the first column i.e x=1 and y=3 we have equation as:
3=m+c-------(1)
on using the second column i.e. x=2 and y=6
we have 6=2m+c---------(2)
on subtracting equation (1) from equation (2) we get:
m=3
and finally on putting value of m in equation (1) we get c=0
Hence, the equation of the line is y=3x.
This equation holds for all the points.
(c)
<em>x is the independent variable</em> and <em>y is the dependent variable </em>since it depends on the value of 'x'. it is thrice the value of x at each point.
0.09-0.089= 0.001 Therefore,0.09 is bigger than 0.089 by 0.001.
Answer:
14 weeks till he has $480
Step-by-step explanation:
He needs $480
He has $60
He has to earn the rest over the span of the next few weeks, which is $30 for an unknown number of weeks.
Let the unknown number be x in our equation
What he needs to buy the TV and Stereo system is $480 which is our total
The $60 dollars he received is a complete variable
hence we can say,<em> 30x+60=480</em>
<u>This is our equation</u> but it isn't simplified.
first, divide everything by 10(it is a common divisor)
<em>3x+6=48</em>
<em>subtract</em> 6 which is complete from the total
3x=42
Make x the subject and divide both sides by 3
x=14
so the unknown number of weeks is 14.
