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

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

The number of cubes Lucy should add is 8.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a pan balance has 3 cubes on one pan and 11 cubes on the other pan.

The equation to represent the situation is 3+c=11

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, c=11-3

c=8

Therefore, the number of cubes Lucy should add is 8.

Answer:

The answer is 28.26 square in

Step-by-step explanation:

As, the diameter if the top = 6 inches

And the area of a circle = 3.14(pi) x radius^2

So here radius = Diameter /2 = 6/2 = 3

So radius = 3 inches

So area = 3.14 x (3)^2

= 3.14 x 9

= 28.26 square in

Answer: 10

Step-by-step explanation:

8v - 4(v + 8 ) = 8

Distribute

8v - 4v - 32 = 8

Combine like terms

4v - 32 = 8

Add 32 to both sides

4v = 40

Divide by 4 on both sides

V = 10

The number of hours it would take Miller's family to reach their destination is [tex]2\frac{2}{3}[/tex] hours.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, The Miller family must drive 8 hours to reach their destination.

The first time they stopped after driving [tex]2\frac{2}{3}[/tex] hours and again for the second time they stopped after driving [tex]2\frac{2}{3}[/tex] hours.

Therefore the total hours they drive is,

= [tex](2\frac{2}{3} + 2\frac{2}{3})[/tex] hours.

= (8/3 + 8/3) hours.

= 16/3 hours.

= [tex]5\frac{1}{3}[/tex] hours.

So, The number of hours they still need to drive is,

= (8 - 16/3) hours.

= (24 - 16)/3 hours.

= 8/3 hours.

= [tex]2\frac{2}{3}[/tex] hours.

28 miles per 4 hours, so you divide them both by 4 and get 28 divided 4

and 4 divided by 4. so its 7/1 which just equals 7. please correct me if im wrong good luck.

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1

New equation: 7 / 1

Simply the newer equation and you have your answer
