Answer:
3(a + 5b + 7c) and 2x(2 + 5y + 11z)
Step-by-step explanation:
3a + 15b + 21c
3(a + 5b + 7c)
4x + 10xy + 22xz
2x(2 + 5y + 11z)
2 and 9 are factors<span> of 18.</span>
<span>When we have two or more given numbers, we can find the largest factor that both numbers have in common. This is called the </span>GCF<span> or the </span>Greatest Common Factor.
There are several different methods that can be used to find the GCF. Let's take a look at some of the methods.
Method 1:<span> List out the factors.</span>
<span>Example: Find the GCF of 64 and 96. </span>
Step 1:<span> List the factors of each number. </span>
64: 1, 2, 4, 8, 16, 32, 64
96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Step 2:<span> Look for factors that both lists have in common.</span>
Step 3:<span> Pick out the largest factor that both lists have in common and call this the GCF.</span>
Therefore, the GCF of 64 and 96 is 32.
Method 2:<span> Upside Down Division</span>
Find the GCF of 280 and 144.
Step 1:<span> Place the numbers inside an upside down division bar.</span>
Step 2:Now, we need to divide both numbers by a common factor. Because both of the numbers are even, we could start with 2.The answer goes underneath the bar.
Step 3:<span> We will continue to divide until we have two numbers that are relatively prime. Remember that relatively prime means two numbers that do not have any common factors other than 1.</span>
<span>35 and 18 are relatively prime. </span>
Step 4:<span> Now we take all of the factors on the side and multiply them together.</span>
Answer: Wouldn't it be $3000 dollar profit? Because 6000-3000 is 3000
Step-by-step explanation:
The simplified expression is 40 + 25e
<h3><em><u>
Solution:</u></em></h3>
Given that, Riley’s parent got a cell phone plan that has a $40 monthly fee for the first phone
For each extra phone,
Phone service charge = $15
Text service charge = $10
<em><u>The expression that represents the total phone bill in dollars is given by:</u></em>
40 + 15e + 10e
Where "e" is the number of extra phones
We are asked to simplify the expression
Combine the like terms. Here like terms are 15e and 10e
Therefore, add 15e and 10e
Thus the simplified expression is 40 + 25e
Answer:
46,213,300 km
Step-by-step explanation:
46,213,267
in the above number ;
7 = units
6 = tens
2 = hundred
3 = thousand
1 = ten thousand
2 = hundred thousand
6 = million
4 = 10 million
to round off to the nearest hundred, look at the number in the tens (6). If this number is greater than or equal to 5, add 1 to the hundreds unit, if this is not the case, add zero
because 6 is greater than 5, add one to the hundred value
= 46,213,300 km
