Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent

Mathematics

docker41 [41]2 years ago
4 0

Answer:

Please specify what the three expressions are.

Step-by-step explanation:

From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:

2(x-3)=2x-6

Then, by evaluating it, you would get:

2x-6=2x-6 by distribution over subtraction.

2x-6+6=2x-6+6 by the additive property of equality

2x=2x Simplify.

x=x by the reflexive axiom.

Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.

Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.

Sorry I could not be of more help, but you did not specify what the expressions were.

There were 63 equal piles of plantain fruit put together and 7 single fruits. They were divided evenly among 23 travelers. What
antiseptic1488 [7]

Answer:

There are 28 fruits in each pile.

Step-by-step explanation:

We are given the following in the question:

Let x denote the number of fruits in each pile and y denote the number of fruits that every traveler receive.

Consider the diophantine equation:

63x + 7 = 23y\\63x-23y = -7

We obtain the greatest common divisor of (63,-23).

The greatest common divisor f 63 and -23 is 1.

Therefore, there exist \alpha,\beta such that

-23\alpha+63\beta=1

By applying extended Euclidean Algorithm, we have,

1 = (1\times 6)+(-1\times 5)\\1 = (1\times 17)+(3\times 6)\\1 = (3\times 23)+(-4\times 17)\\1 = (-4\times 40)+(7\times 23)\\1 = (7\times 63)+(-11\times 40)\\1 = (-11\times -23)+(-4\times 63)

1 = (-11\times -23) + (-4\times 63)

Multiplying -7 on both sides, we get,

-7 = (77\times -23) + 28\times 63)

Thus, we get,

x = 28\\y=77

Thus, there are 28 fruits in each pile.

U're goal is to get k alone.
So divide both sides by 9/10.

Seven pizzas are shared equally between three friends. What fraction of pizza does each friend get? Write your answer as a mixed
vredina [299]

Seven pizzas: 7 pizzas

Shared between 3 friends: 7 pizzas / 3 friends

Simplify the fraction:

7 / 3

(3 goes into 7 twice, 7 - 6 = 1)

2 1/3

The fraction of pizza that each friend gets is 2 1/3.

Hope this helps!! :)

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
il63 [147K]

y = mx + c

7 = 4(-8) + c

c = 39

The equation is y = 4x + 39

y - 7 = 4 ( x - (-8))

y -7 = 4 (x +8)
