Find the least common multiple of 45 and 120
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{360}}}}}[/tex]
Step-by-step explanation:
Steps for finding L.C.M of the given numbers :
[tex] \star[/tex] First of all find the prime factors of each numbers.
[tex] \star[/tex] Take out the common prime factors.
[tex] \star[/tex] Also take out the remaining prime factors.
[tex] \star[/tex] Multiply those all prime factors and obtain L.C.M. If there is not any common prime factors then their L.C.M is the product of the given numbers.
Now,let's find the least common multiple ( L.C.M ) of 45 and 120 following those steps :
prime factors of 45 = 3 × 3 × 5
prime factors of 120 = 2 × 2 × 2 × 3 × 5
Common prime factors= 3 and 5
Remaining prime factors = 2 , 2 , 2 and 3
Multiply all the prime factors to obtain L.C.M
[tex] \dashrightarrow{ \sf{3 \times 5 \times 3 \times 2 \times 2 \times 2}}[/tex]
[tex] \dashrightarrow{ \boxed{ \sf{360}}}[/tex]

explain how 5x-3y=2 and 5x-3y=8 are parallel without doing any calculations
Answer:
They're parallel because the first part of the equations have the same numbers/variables (can see down below in bold). This tells us whether or not it's parallel. There's no need for any calculations due to this.
5x - 2y = 2
and
5x - 2y = 8
The answer of the equations doesn't affect it, only is they're the same number. Then it becomes overlap.
For Example:
5x - 2y = 9
and
5x - 2y = 9
they're the same, meaning overlap.

Answer: [tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex]
Step-by-step explanation:
To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[tex]\frac{y+4}{y-8} +\frac{y-8}{y+4}[/tex] [multiply first fraction by y+4 and second by y-8]
[tex]\frac{(y+4)(y+4)}{(y-8)(y+4)} +\frac{(y-8)(y-8)}{(y-8)(y+4)}[/tex] [distribute by FOIL]
[tex]\frac{y^2+8y+16}{(y-8)(y+4)} +\frac{y^2-16y+64}{(y-8)(y+4)}[/tex] [add numerator]
[tex]\frac{y^2+8y+16+y^2-16y+64}{(y-8)(y+4)}[/tex] [combine like terms]
[tex]\frac{2y^2-8y+80}{(y-8)(y+4)}[/tex] [factor out 2 from numerator]
[tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex]
Now we know that [tex]\frac{2(y^2-4y+40)}{(y-8)(y+4)}[/tex] is the factored form after adding.

Solve the equation |x + 6|= |x– 12|. Graph the solutions, if possible.
Answer:
x=3
Step-by-step explanation:
Answer:
Step-by-step explanation:
|x+6|=|x-12|
x+6=±(x-12)
when x+6=x-12
6=-12
which is impossible hence rejected.
x+6=-(x-12)
x+6=-x+12
x+x=12-6
2x=6
x=6/2=3
so x=3

There are 9 boys and 6 girls in a hall, each holding coins in their hand. The mean number of coins for the children is 18 The mean number of coins for the boys is 14 Work out the mean number of coins for the girls.
Answer:
24
Step-by-step explanation:
Average = total number of coins / number of students
If the mean number of coins with boys is 14, the total number of coins held by boys = 14 x 9 = 126
The total number of coins held by the students = total number of children x average number of coins held by the children
15 x 18 = 270
The total number of coins held by girls = 270 - 126 =144
The mean number of coins for the girls = 144 / 6 = 24
The map shows a straight highway between two towns. Highway planners want to build two new rest stops between the towns so that two rest stops divided the highway into three equal parts. Find the coordinates of the points at which the rest stops should be built.
1,1 and -1,0 would be the answer
(-2, -1/3) and (1, 1 1/3) the coordinates of the points at which the rest stops should be built.
What is coordinates point?
A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.
According to the question,
In given figure,
x from -3 to +3
1/3 would be -2
2/3 would be +1
y from -2 to +3
1/3 would be -2 + 5/3 = -1/3
2/3 would be -2 + 10/3 = 1 1/3
The two coordinates
(-2, -1/3) and (1, 1 1/3)
Hence , (-2, -1/3) and (1, 1 1/3) the coordinates of the points at which the rest stops should be built.

A parking garage charges $2 for the hour and $1 each additional hour. Fran has $9.90 to spend for parking. What is the greatest number of hours Fran can park
Answer:
Frank can park 8.9 hours at the highest
Step-by-step explanation:
Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.
From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.
Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x
By adding this to the initial $2, we have the total $9.90
So, mathematically;
2 + x = 9.90
x = 9.9 -2
x = 7.9 hours
Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours
