Answer:
3.95m + 8.95b = 47.65
Why?
It cannot be the first or second equation since the total amount was $47.65, not $60.55 or $47.95.
It’s either the third or fourth equation. You can tell it’s the third one since in the question it states “Let m represent the number of magazines and b represent the number of books.” The fourth equation gets it reversed by saying each magazine costs $8.95 and each book costs $3.95, when in reality it’s the other way around.
Therefore, the third equation most accurately depicts this situation.

If the width of a rectangle is 3 yards less than it’s length and the perimeter is 130 yards, what is the length and the width.
Marianna [84]

Answer: P=130

2W +2L=130

2(31) + 2(34)=130

W=31

L=34

Step-by-step explanation:

P=130

2L + 2W

W=L-3

Add all of the sides together to get perimeter.

2(L-3) + 2L=130

2L-6+2L=130

4L-6+6=130+6

4L=136

4L/4=136/4

L=34

W=L-3

W=34-3

W=31

The angles in a triangle are 100, 40, and 40 degrees. Classify the triangle by its angles and sides.
lara [203]

Answer:

F. Obtuse isosceles

Step-by-step explanation:

Since we have an angle that is 100 degrees, we have an obtuse angle

We have two angles that are 40, which means we have two sides that are equal length, because two angles have the same measure.  That means it is isosceles

The triangle is an obtuse isosceles

Lera25 [3.4K]

Answer:

∠ ABD = 42°

Step-by-step explanation:

∠ ODC = 90° ( angle between tangent and radius )

∠ ADC = 90° - 48° = 42°

The angle between a tangent and a chord is equal to the angle in the alternate segment, that is

∠ ABD = ∠ ADC = 42°
