The answer is 5 and associative property
3/7*5/6
cross out 3 and 6
divide by 3
3/3= 1
6/3= 2
1/7*5/2
mutiply the denominators together
7*2= 14
mutiply the numerators together
1*5= 5
Answer:
5/14
150
13+46= 59
59+87= 146
Round 46 to the nearest ten, which in this case would be 50 because the last number is larger than a 5.
Then add the 1 back in to make it 150.
Answer:
(x, y) = (77/240, -3/10)
Step-by-step explanation:
It is convenient to write the equations in standard form.
Multiplying the first equation by 21 gives ...
21y = 24x -14
Multiplying the second equation by 8 gives ...
24x +9y = 5
Then the system of equations in standard form is ...
Subtracting the first from the second, we get ...
(24x +9y) -(24x -21y) = (5) -(14)
30y = -9
y = -9/30 = -3/10
Substituting this into the second equation, we have ...
24x +9(-3/10) = 5
24x = 7.7 . . . . . . . add 27/10
x = 7.7/24 = 77/240
The solution is (x, y) = (77/240, -3/10).
An expression that represents the perimeter of the rectangle would be:
P = 2(3n+2) + 2(n-1)
Hope this helps!
