A student is trying to find the sum of 5/6 + 3/4 + 1/5 They first tried to use 24 as a common denominator. Why does 24 not work as a common denominator?
Answer:
24 does not work as a common denominator because it is not the Lowest Common Multiple of 6, 4 and 5.
Step-by-step explanation:
In that above question, we are told that:
A student is trying to find the sum of 5/6 + 3/4 + 1/5
Step 1
The first step would be to find the Lowest Common Multiple of the denominators (6, 4, 5).
Lowest Common Multiple can be defined as the number that is the lowest quantity of the multiple of 2 or 3 number.
The lowest common multiple for 6, 4, 5 = 60. This is that number that the 3 denominators can be divided in
Hence,
5/6 + 3/4 + 1/5
= 5 × 10 + 3 × 15 + 12× 1/60
= 50 + 45 + 12/60
= 107/60
= 1 47/60
24 does not work because it is not the Lowest Common Multiple of 6, 4 and 5.
The lowest common multiple for the 3 denominators = 60, therefore 60 should be used.

In an AP with 18 terms the common difference is $-3$−3 . If the nth term is $-5$−5, what is its first term?
Answer:
46
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here d = - 3 and [tex]a_{18}[/tex] = - 5 , thus
a₁ + (17 × - 3) = - 5
a₁ - 51 = - 5 ( add 51 to both sides )
a₁ = 46
Answer:
a = 46

What value of x with make the equation below true?
1/2 (2x + 8) = 3x + 8 - x
Please help
Answer:
Step-by-step explanation:
1/2 (2x+8)=3x+8−x
Use the distributive property to multiply 1/2=0.5 by 2x+8.
1/2 x 2x+1/2x8=3x+8-x
Cancel out 2 and 2.
x+1/2 ×8=3x+8−x
Multiply 1/2 =0.5 and 8 to get 8/2=4.
x+8/2=3x+8−x
Divide 8 by 2 to get 4.
x+4=3x+8−x
Combine 3x and −x to get 2x.
x+4=2x+8
Subtract 2x from both sides.
x+4−2x=8
Combine x and −2x to get −x.
−x+4=8
Subtract 4 from both side
−x=4
Multiply both sides by −1.
x=−4
Given f (x) = 2x+1, find when f (x) = 9
Steps to solve:
f(x) = 2x + 1
~Substitute
f(9) = 2(9) + 1
~Multiply
f(9) = 18 + 1
~Add
f(9) = 19
Best of Luck!
Answer:
19
Step-by-step explanation:
substitute 9 in x and you get 18 then add 1 so total u get 19

What is .33 converted to a fraction in simplest form
Answer: 33/100
Step-by-step explanation:
.33 is in the hundreths place, so the denominater would be 100. So, it would 33/100. You can't simplify it.
Solve |7x+42| =14x. Identify the solution and an extraneous solution.
Answer:
x = 140.3333333........
Step-by-step explanation:
17x+421 = 14x
move the numbers with x's to the left and 421 to the right so it makes
17x then 14x is positive but moved to the opposite side it becomes negative.
Then 421 is positive on the left so moved to the right makes it negative.
Which is 17x-14x=(-421)
then you do 17x mines 14x which is 3x
3x = (-421)
Now your goal is to isolate your variable x. So divide both sides by 3 because x is multiplied by three you need to do the opposite.
x = 140.3333333..........

If a and bare negative, then a + b is also negative.
Step-by-step explanation:
Example: -2+-5
It can also be written as -2-5.
How I do these problems, I do 2+5, which is 7. Then I add a negative sign. So -2+-5 or -2-5 is equal to -7.
-a+-b can also be written as -a-b. So yes, if a and bare negative, then a + b is also negative.
hope it helps!

Read the following statement: Line segment CD is congruent to line segment XY.
Which of the following is an equivalent statement? (4 points)
what is the value of x if segment BC is 2x+4 and line Ac is 24
Greetings from Brasil
Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).
From the attached drawing we can conclude that:
AB + BC = AC
where
AB = Y
BC = 2X + 4
AC = 24
then
AB + BC = AC
Y + (2X + 4) = 24
X = (20 - Y)/2In my view this question is incomplete
At the fair the ratio of male to females was 8:6. If there are 112 people at the fair how many males are there?
Answer:
64
Step-by-step explanation:
Let the common multiplier of the given ratio be x.
Therefore,
Number of males = 8x
Number of females = 6x
[tex]8x + 6x = 112 \\ 14x = 112 \\ x = \frac{112}{14} \\ x = 8 \\ number \: of \: males = 8x = 8 \times 8 = 64 \\ [/tex]
how do I isolate V1 in this equation
[tex]\frac{P_{1}V_{1} }{T_{1} } = \frac{P_{2}V_{2} }{T_{2} }[/tex]
Let's start off by multiplying each side by [tex]T_{1}[/tex]
[tex]P_{1}V_{1} } = \frac{P_{2}V_{2} T_{1} }{T_{2} }[/tex]
Divide each side by [tex]P_{1}[/tex]
[tex]V_{1} = \frac{P_{2}V_{2} T_{1} }{T_{2}P_{1} }[/tex]

Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob’s checking account?
Answer:
$702.53
Step-by-step explanation:
178.74
36,52+18.92+25.93=81.37
178.74-81.37=97.37
300+100+205.16=605.16
605.16+97.37=702.53

Write the equation g(x) of the transformation of the parent graph f(x) = |x| stretched horizontally by a factor of 3.
Answer:
g(x) = |1/3x|
Step-by-step explanation:
f(x) = |x|
y = f(Cx) 0 < C < 1 stretches it in the x-direction
g(x) = |1/3x|
We can start with: f(x) = |x|
0 < c < 1 means x-direction stretch
y = f(cx)
3 unit horizontal stretch
After: g(x) = |1/3x|
