Notice that the sequence involves subtracting 10 units from the previous term. Then, we are in the case of an arithmetic sequence with common difference = -10, since we build the next rem by subtracting 10 from the previous. so we have:
term 1 = 42
term 2 = 42 - 10 = 32
term 3 = 32 - 10 = 22
term 4 = 22 - 10 = 12
term 5 = 12 - 10 = 2
term 6 = 2 - 10 = -8
term 7 = -8 - 10 = -18
Answer:
<u>2</u>
Step-by-step explanation:
Take two points which lie on the line :
Gradient (slope) formula :
- m = y₂ - y₁ / x₂ - x₁
- m = 3 - 1 / 1 - 0
- m = 2/1
- m = <u>2</u>

Answer:
A handyman need 34 rows of 18 tiles.
How many total tiles does he need?
lets start off by saying that each row has 18 tiles
and there are supposed to be 34 rows
so you can multiply the number of tiles in each row (18) by the number of rows (34)
34 x 18 = 612
the handyman needs a total of 612 tiles to cover the floor.

Answer:
x = 14
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
27x = 378 ( divide both sides by 27 )
x = 14
