Answer:
(5x-3)(2x-5)
Step-by-step explanation:
10x^2 - 31x + 15
=(10x^2-6x)+(-25x+15)
=2x(5x-3)-5(5x-3)
=(5x-3)(2x-5)
I hope this helps!
Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out
1. set up the problem
5 x 2/3
2. put a 1 on 5 to make it a fraction
5/1 x 2/3
3. multiply and divide
(5 x 2) / (1/3)
4. find out the answer
10/3
5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1
6. it equals
3 1/3
7. so the answer is
3 1/3

Answer:
72 kph
Step-by-step explanation:
The first sentence tells you the speeds are proportional. So, you can write the proportion ...
kph/mph = 120/75 = x/45
Multiplying by 45 gives x:
x = (45)(120/75) = 72
72 kph is 45 mph.
To cover at least 170.5 sq.ft. the width must be at least 11 feet
W=170.5sq.ft / 15.5 ft = 11ft
