Step-by-step explanation:
Step:1
From given, the rate is
= 15 miles per gallon
= \frac{15}{1}115 = 15 miles.........................(1)
Step:2
Check for Option A,
= 30 miles per 3 gallons
= \frac{30}{3}330 = 10 miles.....................(2)
From the eqn (1) and (2),
Eqn (1) ≠ Eqn (2)
Step:3
Check for Option B and C are not match with given because, Miles provided first or top then the gallons provided the last or bottom.
Step:4
Check for Option D,
= 60 miles per 4 gallons
= \frac{60}{4}460 = 15 miles.........................(3)
From the eqn (1) and (3),
Eqn (1) ≠ Eqn (3)
Result:
The equivalent unit rate for 15 miles per gallon is 60 miles per 4 gallons (\frac{60 miles}{4 gallons}4gallons60miles ) .
765 / 9 = 85
9*100 = 900 but this is too much
900 - 765 = 135
9 goes into 135 15 times (9*10=90 which leaves 45 which is 9*5 so 5+10) so you minus 15 from the 100 that made 900
so 100 - 15 = 85
Answer:
factorise out a and x :
but from general factorization:
a » x
b » 2
therefore:
Answer:
2x^2-2x
Step by Step Explanation:
The 2 x^2 come together to form 2x^2 and since there is no other number that has x but no ^2 -2x stays the same.
