3x + x = 1044
4x = 1044 - divide both sides by four
x = 261
coffee table - $261
couch - $783
Since n>2 n
n can be 3 for example
so a3=t
and from the sequence we know a3 = 15
because it is the product of a1(3) and a2( 5)
so t = 15

Answer:
<em>(a) The system that models the situation:
and
</em>
<em>(b) David needs 40 pounds of bread flour and 240 pounds of cake flour.</em>
Step-by-step explanation:
The amount of flour mixture is 280 lb. that is 8% plain flour.
So, the amount of plain flour in the mixture will be:
lb.
The number of pounds of bread flour and cake flour needed to make the new mixture are
and
respectively.
<u>So, the first equation will be</u>: 
The bread flour has 14% plain flour and the cake flour has 7% plain flour.
Thus, the amount of plain flour in bread flour
lb. and the amount of plain flour in cake flour
lb.
<u>So, the second equation will be</u>: 
From equation (1), we will get: 
Now substituting this
into equation (2) in place of
........

Plugging this
into equation (1), we will get.....

So, David needs 40 pounds of bread flour and 240 pounds of cake flour.
Answer:
-10
Step-by-step explanation:
y : x
= 5 : 4
4z = -8
= -8 / 4 = -2 = z
y : x
= 5 * -2 : 4 * -2
= -10 : -8
