Answer: B) Addition Property

Step-by-step explanation:

The Step 3 is: $3x-30=0$

The idea is to solve the equation, which means that you have to find the value of the variable $x$ .

As $3x-30$ is a subtraction, you need to add 30 to both sides of the equation to keep the equation balanced. This property is known as "Addition property of equality".

This property states that adding the same number to both sides of the equation, the equality does not change:

$a=b\\a+n=b+n$

Then, the Addition property of equality applied in Step 3, get you to Step 4:

$3x-30+(30)=0+(30)\\3x=30$

Write -12 in the improper fraction form.

nydimaria [60]

Answer:

$\frac{-12}{1}$

Step-by-step explanation:

An Improper Fraction has a top number larger than (or equal to) the bottom number.

To convert a whole number -12 into an improper fraction we can divide the whole number by one to turn it into a temporary fraction.

$\frac{-12}{1}$

Also we could multiply and divide -12 by another number greater than one, for example:

$\frac{-12*2}{1*2} = \frac{-24}{2}$

There are several ways we can write -12 in the improper fraction form.

Write an equation to describe this situation using decimals. “Tessa bought x pounds of almonds. Lark (y) bought more than

kvasek [131]

Answer:

y = 1.6x

Step-by-step explanation:

y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.
