Question

answer the following:

Answer 1

Answer:

Q1. construst 3 equations starting with p = -5

Sol: 1. px+682=572+80

2. p+1=80-85(+1)

3. p+6y=427+60

Note:

there is no solution for question 24 as the triangle DEF can not be constructed because there is a rule for construction of a triangle which is that the sum of 2 sides of a triangle is greater thann the 3rd side and while following this important rule,we cannot contruct the given triangle.

Sol.25:

30pq+12q+14p-(24pq-10q-18p)

=30pq+12q+14p-24pq+10q+18p

=30pq-25pq+12q+10q+14p+18p

=6pq+22q+32p

Note:

Follow the Bodmas rule while solving level maths question.the bodmas rule is:

Brackets

Of

Division

Multiplication

Addition

Subtraction

This means you firstly have to break the brackets of the question followed by solving the 'of' .If you ever find an 'of' in a question this means you have to multiply the terms between which the 'of' is.After solving the 'of' you have to do division followed by multiplication,after which you have to do addition and ultimately solve the expression or equation by solving the terms which need to be subtacted.

Hope this helps.

Thanks to you for this interesting question
