Answer:
25 and 30
Step-by-step explanation:
Let the smaller consecutive multiples of 5 be x. Therefore, other consecutive multiples will be x + 5.
Now as per statement the sum of two consecutive multiples of 5 is 55. To find the multiples. Thus
x + x + 5 = 55
2x + 5 = 55
2x = 55 - 5
2x = 50
x = 50/2
x = 25
This the smaller consecutive multiples of 5 is 25, the other consecutuve multiple is x+ 5, 25 + 5 = 30.
The consecutive multiple numbers of 5 are 25 and 30
Answer the two consecutive multiples of 5 are 25 and 30
2x^3 + 9x - 8 - (4x^2 - 15x + 7)....distribute thru the parenthesis
2x^3 + 9x - 8 - 4x^2 + 15x - 7....combine like terms
2x^3 - 4x^2 + 24x - 15 <==

Answer:
2.8 liters
Step-by-step explanation:
So there are various ways to do this problem, this is just MY preferred way.
Since we are given 1/4th of a total value with 14 liters, we can actually make this 4/4 by multiplying our given value by 4. In this case, 14 liters for 25% becomes 56 liters for 100% antifreeze.
Since we know have a percent of 100%, we can proceed to take 10% increments, all the way up to 30%
10% is 5.6, multiplied by 3 is 16.8
While you might want to put 16.8 instantly, don't forget we are looking for how much is ADDED from 25%, not just how much there is.
In this case, subtract 14 from 16.8 to come out with a grand total of 2.8 liters added.
Answer:
-22/3
Step-by-step explanation:
to convert a mixed number to an improper fraction:
whole number × denominator + numerator
keep the denominator
-8 × 3 + 2
-24 + 2
-22
keep denominator
-22/3
