M stands for a whole number greater than 10 and less than 20

Mathematics
1 answer:
Kobotan [32]3 years ago
8 0
10 < m < 20
So m can be 11, 12, 13, 14, 15,16, 17, 18 or 19

2 < n < 10
So n can be 3, 4, 5, 6, 7, 8 or 9
Q1. What is the smallest number that m times n could be? That would be the product (the "times") of the two smallest number in each range, so 11 times 3 = 33.

Q2. What is the largest number that m - n could be? Here we want to make the difference between the two numbers the largest. So we take the largest value for m which is 19 and the smallest number for n, which is 3.

19 - 3 = 16.

Answer:

Step-by-step explanation:

The first step contains the error.

2x - 10 =    22            Add 10 to both sides

   + 10     +10

2x = 32                      Divide by 10

2x/2 = 32/2

x = 16

4. Kiran's uncle is 54 years old. He is 8 years older than three times Kiran's age. Find Kiran's age,​
levacccp [35]

Kiran's age = x

Uncle's age = 54

Also,

Uncle's age = 8 + 3x

Now,

8 + 3x = 54

3x = 54 - 8

3x = 46

x = 46/3

x = 15.33

x = 15 (rounded)

The sum of the digits of a three-digit number is 6. The hundreds digit is twice the units digit, and the tens digit equals to th
EleoNora [17]
A+b+c=6, a=2c, b=a+c using a and b in the first equation gives you:

2c+a+c+c=6  now use a=2c again

2c+2c+c+c=6

6c=6

c=1, since a=2c

a=2, since b=a+c

b=3

So the number is 231.

Given the equation Square root of 8x plus 1 = 5, solve for x and identify if it is an extraneous solution.
Kisachek [45]
Do recall that squaring and the *radical sign* cancel each other out... like so:(\sqrt{a})^{2}= a

When you put it that way, it isn't enough :P
(\sqrt{a})^{2}= a
(\sqrt{8x+1})^{2}=?

so you start with
(\sqrt{8x+1})^{2}= (5)^{2}
8x+1=25 <-- subtract 1 to both sides
8x=24 <- divide 8 to both sides
x= 3

To find out if it's an extraneous solution ask yourself: It mustn't result in a radical that I like to call... 'illegal'. Plug it into the radicand 8x+1 and make sure you get something that is not a negative number.... so, DO you get a negative number when you plug in x = 3 into the radicand?

(extraneous solution is a invalid solution)

x=3 not extraneous
