Answer 1

Answer:

1) simply by addition

2) by taking lcm of denominator

3) shifting variables in lhs and rhs

4) the variable having highest power is degree

5) by writing what is given in question and assuming variables for unknown

Answer 2

Answer:

ans 1=The total number of these rational numbers is same as the number of integers between -40 and 70, i.e., 70 - (-40) - 1 = 70 + 40 - 1 = 110 - 1 = 109. Similarly, by re-writing -4/7 and 2/7 as -400/700 and 200/700, we can insert 700 - (-400) - 1 = 700 + 400 - 1 = 1100 - 1 = 1099 rational numbers between -4/7 and 2/7.

ans 2= Cross-multiply the two fractions and add the results together to get the numerator of the answer. Suppose you want to add the fractions 1/3 and 2/5. ...

Multiply the two denominators together to get the denominator of the answer. ...

Write your answer as a fraction.

ans 3= Expand all brackets.

Rearrange the terms so that all terms containing the variable are on one side of the equation and all constant terms are on the other side.

Group like terms together and simplify.

Factorise if necessary.

Find the solution and write down the answer.

ans 4= I don't know the answer

ans 5= Start Word 2016 and open a document to work in. Position the cursor at the point where you want the equation to be inserted. 2. To bring up the Equation Editor, On the Insert tab, in the Symbols group, click the arrow next to Equation, and then click Insert New Equation
