Answer:
see explanation
Step-by-step explanation:
(1)
=
( cross- multiply )
6p = 8 ( divide both sides by 6 )
p =
= ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
(2)
=
( cross- multiply )
7n = 32 ( divide both sides by 7 )
n = ![\frac{32}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B7%7D)
(3)
=
( cross- multiply )
3x = 20 ( divide both sides by 3 )
x = ![\frac{20}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B3%7D)
Answer:
The other factor is 5x-2
Step-by-step explanation:
Using the factorisation method:
Two numbers that multiply to give -10 and add to give +3:
+5 and -2
![5x^{2} +5x-2x-2](https://tex.z-dn.net/?f=5x%5E%7B2%7D%20%2B5x-2x-2)
![5x(x+1) -2(x+1)](https://tex.z-dn.net/?f=5x%28x%2B1%29%20-2%28x%2B1%29)
![(x+1)(5x-2)](https://tex.z-dn.net/?f=%28x%2B1%29%285x-2%29)
So the other factor is 5x-2
I'm not sure about the second part of the question but I hope you understood how to deal with the first part.
Last week she walked at 18/6 = 3 mph
this wee her pace is 2.5 mph
First statement must be true.
