Scilla [17]

Answer: 4m

Step-by-step explanation:

Note : midpoints divide a line into two equal parts.

To calculate the length of SA;

We can consider the large triangle QRS with

Two midpoints :

A on the line QS, QA = 4m ;

and B on the line RS with RB = 3m

Fron the definition of midpoint :

QS = QA + AS

where QA = AS

QS = 2QA = 2AS

Therefore,

QA = QS

4m = 4m

What is the solution of this equation? -9+7b=8b-7

Anni [7]

Answer:

$b=-2$

Step-by-step explanation:

$-9+7b=8b-7\\-9+9+7b=8b-7+9 \leftarrow \text {Addition Property of Equality} \\7b+8b=2\\7b-8b+8b-8b=2\leftarrow \text {Subtraction Property of Equality} \\-b=2\\\frac{-b}{-1}=\frac{2}{-1} \leftarrow \text {Division Property of Equality}\\\boxed {b=-2}\\\\\huge\text {The value of 'b' should be -2}$
