Answer:
x=3.5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of one triangle over the same side of the other triangle.
6 4.2
------ = ----------
5 x
Using cross products
6x = 5*4.2
6x =21
Divide by 6
6x/6 = 21/6
x=3.5
Answer:
7 Rows with one row having 6 Chairs. The other 6 Rows will have 8 chairs each.
6x8 = 48 chairs + 1x6 = 54 chairs.
Step-by-step explanation:
1 Row = 8 Chairs [1Row/8Chairs]
(1Row/8Chairs)*(54Chairs) = (54/8) Rows = 6.75 Rows
The manager needs 7 rows, one row will have only 6 chairs [(0.75 Rows)*(8Chairs/1Row) = 6 Chairs
Q(4X+2)=36X+18
so,for x=5; yes
