write two equivalent expressions involving decimals that illustrate the distribute property.

4.2(1.9+0.4)=3.8(6.1-3.558)

Step-by-step explanation:

I'm not quite sure if this is what is being asked, but all you need to do now is check to make sure that both sides are equal to each other:

Distribute on both sides: (4.2*1.9)+(4.2*0.4)=(3.8*6.1)-(3.8*3.558)

Simplify inside the parenthesis: 7.98+1.68=23.18-13.52

Simplify both sides of the equation: 9.66=9.66

Since 9.66 is equal to 9.66, that means that this expression is correct. On top of that, it exemplifies the way that the Distributive Property works; by distributing or applying one term to all existing terms inside of a set of parenthesis.

I hope this helps!

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

the answer i believe is 27 units.
