Answer:
11+6x
Step-by-step explanation:
(–2x + 10) – (–8x – 1)
This is an algebraic expression. An algebraic expression is an expression with no equality sign. When an expression has multiple signs, the rule of BODMAS is used. That is Bracket of Division Multiplication Addition and Subtraction, and it will be solved I'm that order.
The expression in bracket would be solved first, and we do that hi opening the bracket
(–2x + 10) – (–8x – 1)
-2x+10+8x+1
Then we collect like terms
10+1+8x-2x
11+6x
An algebra can only be simplified to the lowest or simplest form.
The dot-plot for the data is sketched at the end of this answer.
--------------------------
- The dot plot shows the <u>number of times each measure appears in the data-set.</u>
<u />
- 68 appears once, thus it is 1 in the dot-plot.
- 69 appears three times, thus it is 3 in the dot-plot.
- 70 appears once, thus it is 1 in the dot-plot.
- 71 does not appears, so it is 0.
- 72 appears once, thus it is 1 in the dot-plot.
- 73 appears five times, so it is 5 in the dot-plot.
- 74 appears once, thus it is 1 in the dot-plot.
- 75 does not appears, so it is 0.
- 76 appears twice, thus it is 2.
- 77 appears once, so it is 1.

Answer:
Step-by-step explanation:
Since we are not given the dimension. Let us say the shape of the patio is a rectangle with length 30m and width 18m.
Area of the rectangle = Length * Width
Area of the rectangle = 30 * 18
Area of the rectangle = 540m²
This means that 540m² of the patio costs $2276.35. To get the cost of each square metre of patio, we will say;
540m² = $2276.35
1m² = x
cross multiply;
540x = $2276.35
x = $2276.35/540
x = $4.22
Hence each square meter of patio will cost $4.22
<em>Note that the dimension of patio was assumed. Same explanation can be employed for any dimension.</em>
