The sum of three consecutive even numbers is 114 what's the smallest of these numbers​
laila [671]

Answer:

36

Step-by-step explanation:

consecutive even numbers are 2,4, 6...

Let the smallest of the 3 numbers be x.

2nd number= x+2

3rd number

=x+2+2

= x+4

sum of the 3 numbers= x +x+2 +x+4

114= 3x+6

3x= 114 -6 (-3 on both sides)

3x= 108 (simplify)

x= 108 ÷3

x= 36

Thus, the smallest number is 36.

Let's check!

36+38+40= 114 ✓

What is the domain of f(x)=-5x+4
ANTONII [103]

Answer:

f(x) = -5x + 4

Domain refers to the values of x that would result to  a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.

Or, plot the given equation to check.

The graph of f(x)=-5x+4 is shown below.

Since the graph is a straight line and can be extended continuously on both ends,  this indicates that every values of x, there is a corresponding value of y.

Hence, the domain of the given function are all real numbers.Step-by-step explanation:

a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbo
FinnZ [79.3K]

Answer:

0.67 / 100 : 31^3 : 31^3 / 25cm^3

x 10

0.67 / 100 = 67 / 10000000  grams/cm  :  29791 / 15625 / 29791    

149253.731  : 0.52

divide by 1000

= 149.253731

= 149.3 kg

Ratio kg = 149.3 : 0.5

Step-by-step explanation:

Mole Ratio

The mole ratio compares the number of moles in a balanced equation.

This is the comparison between the coefficients in front of the chemical formulas.

If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.

Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.

Mole Ratio Units

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
