What properties can be used to solve 7y-15=-29. Identity property of multiplication,addition property of equality ,distributive

Sveta_85 [38]

Answer:

Addition Property of Equality.

Inverse property of multiplication.

Step-by-step explanation:

Given the equation:

$7y-15=-29$

First of all, let us use Addition Property of Equality.

According to the property, if we add a number on both sides of an equality, there is no change in the equality.

In other words, the equality will be same if we add the same number on Left Hand Side and Right Hand Side of the equality.

First of all, let us add 15 on both sides of the equality:

$7y-15+15=-29+15\\\Rightarrow 7y=-14$

Now, let us Inverse property of multiplication.

i.e. Multiplication of a number with its inverse is equal to 1.

$a\times \frac{1}{a} = 1$

So, let us multiply the given equation with $\frac{1}7$

$7y \times \dfrac{1}{7}=-14 \times \dfrac{1}{7}\\\Rightarrow 1y =-2\\\Rightarrow y=-2$

The properties used are:

Addition Property of Equality.

Inverse property of multiplication.

1) Una bicicleta circula en línea recta a una

erica [24]

Answer:

the distance covered is 11.25 km

Step-by-step explanation:

Given that

The speed of the bicycle is 15 km/h

And, the time taken of the bicycle is 45 minutes

We need to determine the distance covered

As we know that

Speed = Distance ÷ Time

So, distance = Speed × time

= 15 km /h × 0.75 hours

= 11.25 km

The 0.75 hours come from

= 45 minutes ÷ 60 minutes

= 0.75 hours

Hence, the distance covered is 11.25 km
