Whats the model because 7/9 × 3/4= 7/12 which also equals to 21/36
as 7/12 is the simplified version of 21/36 but then for c 4×9 =36 so I'm a bit confused my self but here's a bit of a start
Answer:
I think it's parallelograms.....
Step-by-step explanation:
Parallelograms; a four-sided plane rectilinear figure with opposite sides parallel.
U=-2b+30
u+b=21
<span>in slope intercept form this is </span>
<span>u=-b+21 </span>
<span>The same thing for wheels is </span>
<span>2b+u=30 </span>
<span>or </span>
<span>u=-2b+30</span>
3 is the slope, (0,-5) is the y-intercept of the graph.
Answer:
The answer to your question is 48 chairs
Step-by-step explanation:
Data
5 rows- 3 chairs left over
3 rows - 21 chairs left over
Process
1.- Write two equations each for each situation
x = number of rows
y = number of chairs
Equation 1 y = 5x + 3
Equation 2 y = 3x + 21
2.- Solve the system by equality
5x + 3 = 3x + 21
5x - 3x = 21 - 3
2x = 18
x = 18/2
x = 9
3.- Find the total number of chairs
y = 5(9)+ 3 y = 3(9) + 21
y = 45 + 3 y = 27 + 21
y = 48 y = 48
4.- Conclusion
There are 48 chairs
