Answer: < n <
Step-by-step explanation:
| 3n - 2 | - 2 < 1
+2 +2
| 3n - 2 | < 3
3n - 2 < 3 and 3n - 2 > -3
+2 +2 +2 +2
3n < 5 and 3n > -1
n < and n >
< n <

Answer: There are 5 counters that can be added without having to regroup.
Step-by-step explanation:
Since we have given that
Number of counters = 24
We need to add without having to regroup.
It means that we should make it a prime number which does not get divided by any other number except 1 and itself.
so, After 24, there is other numbers that has chances are as follows:
25,26,27,28,29......
But except 29 all the other number can be regroup as they are composite numbers.
But 29 is the nearest prime number after 24.
So, 24+5=29.
Hence, there are 5 counters that can be added without having to regroup.
Ignore the negative sign for now.
3.75
Split the number into its whole number component and decimal component
3.75 = 3 + 0.75
For the decimal component, 0.75 is the same as 75/100
75/100
Find the GCF (Greatest Common Factor) of 75, 100
GCF = 25
Divide both the numerator and the denominator by the GCF
75 ÷ 25/100 ÷ 25
Simplify
3/4
Combine the whole number component with the fraction
3 3/4
Add the negative sign back
-3 3/4
Answer:
Step-by-step explanation:
If it's parallel, that means it has the same slope: -1/5.
Use point-slope form to write the equation:
y - 4 = -1/5 (x - 7)
If you wish to write in point-intercept form:
y - 4 = -1/5 x + 7/5
y = -1/5 x + 27/5
If two lines are parallel, it means that they will have the same gradient:
And remember, the equation of a line is y = mx +c
-----------------------------------
So we know that the equation of the parallel line is:
y = - x + c through point (7, 4)
All we need to do now is to work out what c is
Note: at point (7,4) x = 7 , and y = 4.
So to work out c, we substitute in the values of x and y, and solve:
y = - x + c
4 = - * 7 + c
4 = -1.4 + c
5.4 = c
----------------------------------
Finally, we just put the value of c back into the original equation
y = - x + 5.4
------------------------------------------
Answer:
The equation of the a line parallel to y = - x + 3 through point (7,4)
is: y = - x + 5.4
