I I 2x+1 I +2 I >1, step by step solution (I I is absolute value)
Answers
The absolute value of x in the inequality I 2x+1 I +2 I >1 showing the step by step solution is x > 2
What is absolute value?The absolute value of a real number x can be defined as the non-negative value of x without regard or consideration to its sign.
It is also known as the modulus of a number.
It is sometimes described as the magnitude of a real number regardless of its sign.
It is important to note that the absolute value must take a positive sign
Given the expression;
I I 2x+1 I +2 I > 1
expand the modulus value
2x + 1 + 2 > 1
collect like terms
2x > 1 + 1 + 2
Add like terms
2x > 4
Make 'x' the subject
x > 4/ 2
x > 2
Thus, the absolute value of x is x > 2

Deborah is saving for a trip. She wants to have at least $74 for each of the 13 days of her trip. If saves $84 each month for 10 months, will she save enough money? 4. Use the strategy of mental math to find the total amount she will save. Then, write a division equation to see if she will save enough 5. Timothy says he can solve this problem a different way. He says that he can compare 84 x 10 and 74 x 18. Do you agree? Explain your thinking.
Answers
Answer:
No she will not save enough money for her trip and she needs $122 more for her trip.
Step-by-step explanation:
Deborah requires $74 each day for 13 days trip
Total least amount needed for the trip = 74*13
= $962
Deborah's saving strategy : she saves $84 per month for 10 months
saved amount at the end of the 10th month = 84*10 = $840
840/10 = $84
This clearly shows she is not saving enough money for her trip. She needs $122 more to support the expense of her trip.
Timothy way
84*10= $840 is to be compared with 74*18 = $1332
This method is also not a feasible one for calculating Deborah's expenses of her trip.

Find the HCF and LCM of 160 and 252 by prime factorisation method and verify that HCF x LCM = Product of the two given numbers.
Answers
Answer:
HCF=4
LCM=10080
HCF x LCM = Product of the two given numbers is verified because 403200=40320
Step-by-step explanation:
HCF of 160 and 252
HCF is the product of common prime factors
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
HCF= 2x2
HCF=4
40 and 63 doesn't come in any other table together so,
HCF= 2 x 2 = 4
Now, finding LCM of 160 and 252
LCM is the product of all factors of both numbers, while if any factor is common, it is considered once.
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
In the given factors 2x2 is common so, it is considered once.
LCM= 2x2x2x2x2x3x5x7
LCM= 10080
Now, checking:
HCF x LCM = Product of the two given numbers.
4x10080=160x252
403200=40320
So, It is verified that HCF x LCM = Product of the two given numbers.
( 2/7x-6 ) - ( 1/7x - 5 )
Answers
Answer:
-1 + [tex]\frac{x}{7}[/tex]
Step-by-step explanation:
( 2/7x-6 ) - ( 1/7x - 5 )
First you should combine 2/7 and x, and 1/7 and x. You do this by "bringing the x up". This is how the expression looks now: (2x/7 - 6) - (x/7 - 5). Notice: when you have 1x you can just remove the 1 since it is implied. The next step is to apply the distributive property. The number we are distributing is -1 to (x/7 - 5). This is how the expression now looks like: (2x/7 - 6) - x/7 + 5. Notice: since 5 was already negative, when we multiplied it by a negative, it became positive. Now we can remove the parenthesis since they are no longer necessary: 2x/7 - 6 - x/7 + 5. The next step is to combine the fractions since they have the same denominator. This is how the expression will look like now: -6 + 5 + [tex]\frac{2x - x}{7}[/tex]. Now we should subtract x from 2x (remember x really just means 1x). This is what we have so far: -6 + 5 + x/7. Lastly, we should add 5 to -6. This is how the finished expression should look like: -1 + x/7.
Hope this was clear!

Answers
Answer:

Step-by-step explanation:
7 - 3 = ? not 4 so sub it
Answer:
Ethan's entire statement is true because he is saying that 7-3=4 and that is correct. If you have seven of something and take away 3 of them then you have 3 left.
Step-by-step explanation:
Take 7 apples for example, if you take away 3 of the apples and then count the left over you will notice that you end up with 4. Also, In a subtraction problem the larger number goes first followed by the smaller number, so that the end result is not a negative number. Hope this helps you.

The first diagram is the given situation.
The second diagram asks you to ignore the 98 degree angle and extend the line making up the 116 degree angle until it hits the parallel line on your right. You can then find the supplement to the vertically opposite angle because angles on the same side of the transversal and are interior angles are supplementary. You should get 64.
The third diagram finds the supplement to the 98 degree angle (and yes the 98 degree angle is back in the picture again). You should get 82
You now have 2 known angles in a triangle. The third diagram finds y and <4 to be 34 That's your answer.

A wheel on a bicycle has a radius of 8 inches. what is the distance it covers if the tire makes 2 full rotations?
Answers
A wheel on a bicycle has a radius of 8 inches. The distance it covers if the tire makes 2 full rotations will be equal to 100.48 inches.
The distance covered by the wheel on a bicycle can be determined by using the formula:
distance traveled = 2 x circumference of the wheel
Where 2 is the number of rotations.
The circumference can be found by using the radius of the wheel in the formula:
C = 2π(r)
C =2π(8)
C =16π
Distance traveled can then be found by:
distance traveled = 2x16π
distance traveled =32π
As π = 3.14
distance traveled= 32 x 3.14 = 100.48 inches
Therefore, the distance covered by the wheel on a bicycle is equal to 100.48 inches if the tire makes 2 full rotations.

==========================================================
Work Shown:
The given values are
sin(u) = -12/13cos(v) = -8/17Through the Pythagorean trig identity, we can find
cos(u) = -5/13sin(v) = -15/17I'm skipping these steps, but let me know if you need me to go over them.
Since u and v are in quadrant 3, this means both sine and cosine are negative here
Using those four items, we can then say the following:
cos(v-u) = cos(v)cos(u) + sin(v)sin(u)
cos(v-u) = (-8/17)*(-5/13) + (-15/17)*(-12/13)
cos(v-u) = 40/221 + 180/221
cos(v-u) = (40 + 180)/221
cos(v-u) = 220/221
This is reduced as much as possible because the GCF of n and n+1 is always 1.
