Answer:

Step-by-step explanation:

7b + 8 < 100

subtract 8 from both sides

7b < 92

divide both sides by 7

b < 92/7 ≅ 13.1

Brian can buy at most 13 books.

Answer: You have to plug in the numbers.

So first let's plug in 13. 7*13+8=99

Now 15. 7*15+8=113

Now 18. 7*18+8=134

Lastly 20. 7*20+8=148

The answer is 13.

Compute and simplify 4 /9 + 13/18 show work
Darya [45]

Answer:

1\frac{1}{6}

Step-by-step explanation:

so first find the common denominator which is 162

so on 4/9 multiply 18 to denominater and numerator which makes it 72/162

next multiply 9 to numerator and denominator in 13/18 which makes it 117/162

so now add:

\frac{72}{162} +\frac{117}{162} = \frac{189}{162}

so now simplification.

189/162 can be reduced by 3

63/54 is our new answer. now we can reduce it by 9

7/6 is our new answer. now we must change it to a mixed number which is 1\frac{1}{6}

hope this helped!

A is center of one circle and C is the center of the other circle. Select all line segments that must have the same length as se
Dominik [7]

Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:

  1. Segment BC.
  2. Segment CD.

<h3>What is a circle?</h3>

A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

<h3>The equation of a circle.</h3>

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

  • h and k represents the coordinates at the center.
  • r represents the radius of a circle.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:

  1. Segment BC.
  2. Segment CD.
