Answer:

multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.

Both sides were multiplied by 3 which still makes them equal

Answer:

The correct option is;

Multiplication Property of Equality

Step-by-step explanation:

The multiplication property of equality states that the product of both sides of an equation by a given number maintains the equality of the sides of the equation

For example, two containers hold the same volume of water, if the volume of water in each of the containers is doubled, they will still hold the same volume on each side.

For the given question, we have;

TR = UI then 3·RT = 3·UI

We have the same value of the multiplier on both sides of the equation therefore, the value of the result of the multiplication will also be the same on both sides of the equation.

On anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. if her rear wheel turns 875 times per

quester [9]

Let the number of times she turns the pedal in one mile be x.

Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

$\frac{4}{7} = \frac{x}{875} \\ \\ \Rightarrow 7x=4(875)=3,500 \\ \\ \Rightarrow x= \frac{3,500}{7} =\bold{500}$

Therefore, she turns the pedal 500 times in one mile.

Suzie solved a linear equation for y. This equivalent equation was her result. y = 7x + 23 Which equations could have been the l

Alika [10]

Answer:

2, 3, 5

Step-by-step explanation:

The question asking for the linear equation Suzie manipulated. The answer should be equal to the starting equation. So, we just need to manipulate the option to y= mx + c format.

1. y + 7x = 23

y= -7x +23 (false)

2. . –7x + y = 23

y= 7x + 23 (true)

3. 2y – 14x = 46

2y= 14x+ 46

y= 7x +23 (true)

4. y – 7x = –23

y= 7x - 23 (false)

5. 7x – y = –23

-y= -7x -23

y= 7x + 23 (true)
