Answer:

3(x+2) = 3x + 6

Step-by-step explanation:

An equivalent expression is an expression that is equal. You need to find if the left and right side of the equal signs are equal to each other by reducing each to simplest terms.

Each of the expressions can be multiplied to find lowest terms by removing the parenthesis.

So 3(x+2) becomes 3x + 6

So x^2(3 + 2) becomes 3x^2 + 2x^2

So 3(x+2) becomes 3x + 6

-3(2+x) = -6 - 3x

Only A has equivalent or equal expressions.

Captain Sparrow and his pirate crew dug up several gold coins. They are dividing the coins amongst themselves so that each perso

Dahasolnce [82]

Answer: 150 coins

Step-by-step explanation: let the number of captain Sparrow and the crew = c

The number of gold = g

This mean each person will get g/c

If there were four fewer pirates, then each person would get 10 more coins means

g/(c - 4) = g/ c+ 10

cg = (c-4)(g+10c) ....... (1)

However, if there were 50 fewer coins, then each person would get 5 fewer coins.

(g - 50)/c = g/c - 5

g - 50 = g - 5c

5c = 50

c = 10

Substitute c in equation 1

cg = (c-4)(g+10c) ....... (1)

10g = (10 - 4)(g + 10×10)

10g = 6× (g + 100)

10g = 6g + 600

4g = 600

g = 150 gold coin.

Therefore they dig up 150 gold coin

Use A: to find the value of x. In order to find that you would have to match one part of the proportion. x should be the numerator over 15 and 12 should be over 20 (The total length of that side of the triangle). Good luck. : )

An online grocery store charges $0.10 per pound of produce for handling and delivery after

love history [14]

Answer:

They must buy 501 pounds of produce for the membership to be worth it.

Step-by-step explanation:

You can solve this question by first finding the difference between $0.10 and $0.25.

With some simple subtraction (0.25-0.10) we can find that the difference is that a non-membership person would pay $0.15 per pound.

You then divide 75 by 0.15 to find the extra weight it would take for the produce to equal $75. You should get 500 pounds.

At 500 pounds, the price would be equal if you had a membership or not.

You then must add 1 pound to make it more favorable to have the membership.

At 501 pounds the person with the membership would pay $125.10 and the person without the membership would pay $125.25

Answer:

The attached graph shows my answer.

Step-by-step explanation:

The graph has to start at the top because the number of carrots has to decrease and the graph slants down to the right because the time has to increase. Then the situation says that he eats one carrot at a time until <u>half</u> are eaten. The graph shows the line going down until approximately half. Then he doesn't eat any more, so the line is horizontal until the end of the graph to show no change.
