Answers

Answer:

Step-by-step explanation:

The correct pairs of equivalent expressions are given below.

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

What is the expression?

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have given that,

All the expression are,

(5 + 2b)+(2b + 3/2)

(-14 + 3/2b)-(1 + 8/2b)

(-10 + b)+(7b -5)

(7/2b - 3)-(8 + 6b)

Now, We have to determine the equivalent expression as;

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

Thus, The correct pairs of equivalent expressions are given below.

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

Answers

Answer:

Step-by-step explanation: 37/ 24 =1 13/24 = 1.5416667

The answer would be 1 13/24

You want to do
8 2/3
7 1/8
———
But you have to have the same denominators so you (x) 1/8 by 3 and 2/3 by 8 to get

8 16/24
7 3/24
————
Then you just subtract 16 and 3 to get 13 and subtract 8 and 7 to get 1 so the answer would be 1 13/24

The Mackinac Bridge in Michigan is the third-longest suspension bridge in the United States.



a. How high above the water is the roadway in meters? Round to the nearest hundredth.

The roadway is about ____ meters above the water.



Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.

The length of the bridge is about ____ kilometers.

Answers

a: 60.66 m
b:8.04 km

The roadway is about 60.66 meters above the water.

The length of the bridge is about 8.04 kilometers.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

The length of the roadway above the water = 199 ft

1 ft = 0.3048 m

Multiply 199 on both sides.

199 ft = 60.66 m

The bridge has a length of 26,372 feet.

1 ft = 0.0003048

Multiply 26372 on both sides.

26372 ft = 26372 x 0.0003048

26372 ft = 8.04 km

Thus,

The roadway in meters is about 60.66 meters above the water.

The length of the bridge in km is about 8.04 kilometers.
