Marge has 4 more than 2 times as many books as Susan. If Marge has 22 books and x is the number of books that Susan has, the relationship can be written as 4 + 2x = 22. How many books does Susan have?

Susan have 9 books.

Explanation:

Given that Marge has 4 more than 2 times as many books as Susan.

Let x represents the number of books that Susan has.

The relationship is written as

To find: Number of books that Susan have.

The number of books that Susan have can be determined by solving the expression for x.

Thus, we have,

Subtracting 4 from both sides of the equation, we get,

Dividing both sides by 2, we get,

Therefore, Susan has 9 books.

what is the question here

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
