Answer:
1/0.7
Step-by-step explanation:
The expression x-y equals to 0.7 so we have to substitute 0.7 in the place of x-y....
----> 1/0.7
Dividing would make this equal to a long division answer (1.42857142857) so let's just leave it as a fraction!
I hope this helps! :)

Answer:
Luis traveled 11.82 km in total.
Step-by-step explanation:
<em>The statement should say</em>: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?
Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):
Therefore, Luis traveled 11.82 km in total.
I hope it helps you!
To find the answer you need to turn them into improper fractions to do that you would multiply the whole number by the denominator and add the top number. 4 3/4 = 19/4 2 2/5= 12/5 So then you would find a common denominator for 19/4 And 12/5 a common multiply of 4 and 5 is 20 so 19/4 would turn into
Answer:
A
Step-by-step explanation:
given the roots of a polynomial, say x = a, x = b and x = c, then
(x - a), (x - b) and (x - c) are it's factors and the polynomial is the product of it's factors.
here the roots are x = 4, x = - 5 and x = 7, hence
(x - 4), (x + 5) and (x - 7) are the factors
f(x) = a(x - 4)(x + 5)(x - 7) ← a is a multiplier
let a = 1 and expand the factors
f(x) = (x² + x - 20)(x - 7)
= x³ + x² - 20x - 7x² - 7x + 140
= x³ - 6x² - 27x + 140 → A
