how can you find the product of positive and negative decimals

Answers

(I have attached an example for reference)

1) Product means multiply, so we will multiply the decimal numbers.

2) First multiply both the numbers just the way you multiply two whole numbers.

3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.

4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.

5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.

4 ¹/₂ d < - 72

Simplify the inequality, then we have

4 ¹/₂ d < - 72

4.5d < - 72

d < - 72 / 4.5

d < - 16

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Step-by-step explanation:

Subtract 5Z5Z from both sides.

19 - 5Z = X - 12

19 − 5Z = X − 12

2 Add 1212 to both sides.

19 - 5Z + 12= X

19 − 5Z + 12= X

3 Simplify  19-5Z+1219−5Z+12  to  -5Z+31−5Z+31.

There are no parentheses so you solve the exponents first.

168÷8+9-20

Next, we do not multiply which makes division our second step.

How do you write (4)(25)-300 as an addition equation

Answers

4 x 25 + - 300 is a way u can do it

(4)(25) - 300 can be written as an addition equation: 100 + (-300).

What is an equation?

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given:

An equation is (4)(25)-300.

To write (4)(25)-300 as an addition equation,

we can break it down into two separate addition equations as follows:

(4)(25) - 300 = (4)(25) + (-300)

To solve this further,

substitute the value 25 x 4 = 100 to the above equation, we get,

= 100 + (-300)

Therefore, the equation in the required form is  100 + (-300).
