30 POINTS Fill in the missing work and justification for step 3 when solving 2(x + 1) = 10.

Step Work Justification
1 2(x + 1) = 10 Given
2 2x + 2 = 10 Distributive Property
3
4 2x = 8 Simplify
5 two times x over two equals eight over two Division Property of Equality
6 x = 4 Simplify
A. 2x + 2 + 2 = 10 + 2; Addition Property of Equality
B. 2x + 2 − 2 = 10 − 2; Subtraction Property of Equality
C. (2x + 2)(2) = 10(2); Multiplication Property of Equality
D. the quantity two times x plus two all over two equals ten over two; Division Property of Equality

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
