Your answer is 1 because 5-0 = 5 and 4- -1 = 5 because u flip the sign then u have 5/5 which equals 1.
Answer: 2 and 4/5
Explanation: To subtract mixed numbers, first subtract the fractions. Notice here however that we have 2/5 - 3/5 which will give us a negative fraction. Since this will cause us a lot of trouble, instead, let's rewrite the first mixed number.
We can do this by thinking of 8 and 2/5 as 7 + 1 and 2/5 or 7 + 7/5 by changing 1 and 2/5 to the improper fraction 7/5. So 8 and 2/5 can be written as 7 and 7/5.
So we have 7 and 7/5 - 5 and 3/5.
Now, subtract the fractions. So we have 7/5 - 3/5 which is 4/5. Then subtract the whole numbers so we have 8 - 5 which is 2.
2 and 4/5 is in lowest terms so 8 and 2/5 - 5 and 3/5 is 2 and 4/5.
Answer:
(a) 42.25 km
(b) 616.85 km
(c) 32.31 cm
Step-by-step explanation:
(a) 1 cm on map: 4225000 / 100000 = 42.25 km on ground
(b) 14.6 cm on map: 42.25 x 14.6 = 616.85 km on ground
(c) 1365 km on ground: 1365 / 42.25 = 32.31 cm on map

The answer is 11.5mile/hr
Answer:
Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10
Step-by-step explanation:
Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.
x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2
Simplify terms.
x^3 − x^2 − 22x + 10
