Answer

<h2>4</h2>

Step-by-step explanation:

Given,

r = 10

Let's create an equation,

3r = 10 + 5s

plugging the value of r

3 \times 10 = 10 + 5s

Multiply the numbers

30 = 10 + 5s

Move 5s to L.H.S and change its sign

Similarly, Move 30 to R.H.S and change its sign.

- 5s = 10  - 30

Calculate

- 5s =  - 20

The difference sign ( - ) should be cancelled on both sides

5s = 20

Divide both sides of the equation by 5

\frac{5s}{2}  =  \frac{20}{5}

Calculate

s = 4

The value of s is 4.

Hope this helps..

Best regards!!

Alan is comparing the cost of a fresh lobster dinner at two different restaurants. The first
Pepsi [2]

Good evening ,

Answer:

The weight : 29 pound

Alan would pay for his dinner : $130

Step-by-step explanation:

Let x represent the weight of the lobster

the cost of the dinner at restaurant 1 is 4x + 14  

the cost of the dinner at restaurant 2 is 3x + 43

Now ,we have to solve the equation :  4x + 14 = 3x + 43

4x + 14 = 3x + 43

⇔ x = 43 - 14

⇔ x = 29

In this case Alan would pay the same amount for his dinner at any restaurant:

the price = 4×(29)+14 = 130

               = 3×(29)+43 = 130.

:)

Jenny's algebraic expression:

y = 33d

where y is the total number of posts

total tweets in 5 days

y = (33)(5)

y = 165 tweets

Antonio's expression:

y = 5d

total tweets in 5 days

y = (5)(5)
