Simplify these expression a.-8p + (-9p)+(-2p) b. -3jk+5jk+(-6jk)

Answer:

2

Step-by-step explanation:

We can find this because it's asking how many times 0.35 goes into 0.7.

Here's an easier example without decimals:

10 / 2 = 5

This is asking how many times 2 goes into 10. The second number in the equation is asking how many times it can go into the first number. In this case, 2 goes into 10 five times.

So in this case, 0.35 goes into 0.7 2 times. To make it easier, you can also do 70 / 35, which makes it easier without the decimals.

Hope this helps!

Answer:

44.5

Step-by-step explanation:

Multiplying 10 with 4.45 using mental math to find the total cost of 10 items. first multiply 0 with 445 which will yield 000, then multiply 1 with 445 which will yield 445 now put a cross beneath last 0 in 000 and write 445 before it and perform addition which will yield 4450 as the decimal was initially was before the second last digit in 4.45, place it accordingly in 4450 which will yield 44.5.

The "one and a half" is written as 1.5, and "half" is written as 0.5 when using decimal notation.

To write "one and a half" and "half" in numbers, you use the decimal representation. "One and a half" is equivalent to 1.5, and "half" is equivalent to 0.5.

In decimal form, numbers are represented with a whole number portion followed by a decimal point and a fractional portion. The whole number portion is "1" for "one," and the fractional portion is "0.5" for "half." When combined, you get "1.5," which represents "one and a half."

Similarly, for "half," the whole number portion is "0," and the fractional portion is "0.5." When combined, you get "0.5," which represents "half."

To summarize, "one and a half" is written as 1.5, and "half" is written as 0.5 when using decimal notation. These representations are commonly used in mathematics, measurements, and various other contexts for expressing quantities in numeric form.

The question is:

How do you write one and a half, half in numbers?

Answer:

yes they were rebels

Step-by-step explanation:

respect is earned, if you act a certain way you will be treated like that

Cromwell's harsh treatment of rebels during the English Civil War can be seen as a pragmatic approach to maintain discipline and discourage uprisings, but also as excessively cruel and counterproductive, particularly in the case of his actions in Ireland. It's worth noting that historical judgments depend heavily on the values and perspectives applied to the past.

Whether Oliver Cromwell should have treated the rebels so harshly during the English Civil War is a matter of perspective and is heavily debated among historians. Cromwell is known for his decisive, and yes, often harsh measures against those who rebelled against the Parliamentarian cause during the war. From a pragmatic viewpoint, one might argue that his harsh treatment of the rebels was necessary to maintain discipline and to discourage other potential uprisings. This included the crushing of the Levellers in the New Model Army and his later actions in Ireland.

However, there is also a compelling argument that his actions were excessively cruel and counterproductive to his stated goals. Numerous historical accounts indicate that his actions in Ireland, including the infamous massacre at Drogheda, served to perpetuate animosity towards English rule, contributing to centuries of tension and conflict.

The difficulty with questions like these is that they often involve value judgements. History, as a discipline, attempts to understand the past 'as it really was', acknowledging that people of the past operated according to different sets of values and contexts.

Step-by-step explanation:

^^

Answer:

see explanation

Step-by-step explanation:

Given

2x - 3 > 11 - 5x ( add 5x to both side )

7x - 3 > 11 ( add 3 to both sides )

7x > 14 ( divide both sides by 7 )

x > 2 ← solution

Hence x can be any value greater than 2, that is

x = 3, 4, 5, ......... or

x = 2.1

Answer:

21ax+4a−12

Step-by-step explanation:

For this case we have to represent the following expression algebraically:

"10 less than x is -45"

So:

10 less than x is represented as: [tex]x-10[/tex]

Then, the complete expression is represented as:

[tex]x-10 = -45[/tex]

Adding 10 to both sides of the equation:

[tex]x = -45 + 10\\x = -35[/tex]

Thus, the value of the variable is [tex]x = -35[/tex]

Answer:

[tex]x = -35[/tex]

Answer: 40$

Step-by-step explanation: before the mowing 20$ if half is on the game before game would be 40

Answer:

He had $ 40 before bought the game.

Step-by-step explanation:

Let x be the original amount ( in dollars ) contained by Ken,

His spending on game = half of his money = [tex]\frac{x}{2}[/tex]

So, the remaining money = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]

Now, his earning = $ 12,

Thus, final amount he has = remaining amount + earning

[tex]\frac{x}{2}+12[/tex]

According to the question,

[tex]\frac{x}{2}+12=32[/tex]

[tex]\frac{x}{12}=20[/tex]

[tex]\implies x= 40[/tex]

Hence, he had $ 40 before bought the game .

Answer: 3rd option

Step-by-step explanation: The answer would be the third option. Let's go through each one and explain why it's correct or incorrect. First of all, our function is y = x - 3 so we can plug numbers into our X and Y. If we follow the function y = x - 3, we have 8 = 10 - 3 which is incorrect for the first one so that can't be it. For the nest one, we have 13 = 10 - 3 which also does not make sense. For the third one, we have 7 = 10 - 3 which is correct. And the last one, we have 3 = 10 - 2 which is wrong. Therefore, the third option is the answer.

Final answer:

Mentally calculating square roots for perfect squares like 31 x 31 or 17 squared is identifying the number that was squared, for instance, 31 or 17 respectively. Larger numbers may require a calculator.

Explanation:

The question is asking how to mentally calculate the square roots of certain numbers. For perfect squares, such as 31 x 31 or 17 squared (which is 17 x 17), the process is straightforward because the square root of a perfect square is the number that was squared.

For instance, the square root of 31 x 31 is 31, and the square root of 17 squared is 17. However, for large numbers like 431 x 431 or 432 squared, while they are also perfect squares, mental calculation might be impractical due to their magnitude, and a calculator would typically be used.

Answer:

The volume of the box is 3/4 cubic meters.

Step-by-step explanation:

We know that volume = length * width * height. We have length, width, and height already, so all we have to do is multiply.

5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.

5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.

15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.
