Please i don’t understand this i don’t understand the least common denominator and how can i write an equivalent fraction.please help me my exam is tomorrow
Answers
Answer:
Least common denominator is the lowest number in similarity that a fraction can share and be divided into
Step-by-step explanation:
For example, in this example 1/5, and 1/2 the least common denominator would be 10 because when putting these fractions together you might want to find the total of what they equal. For example, think of this example as a pizza, to make one whole pizza in the first one would be 5 pieces but instead of all five pieces, all you have left is 1 piece of the five. so you only have 1/5. now just imagine you had another pizza the same size of the first one but instead of five pieces you it's only two pieces however, from this two piece pizza all you have left is 1/2. You want to find the in terms of what fraction would make them both equal each other in which you would eventually be able to find out how much pizza you would have left. The denominator is the lower number under the fraction where that is the one most needed for a fraction to change. The least common denominator is a number that goes into both fractions that in reverse can be divided by against each other. our denominators are 5 and 2. Numbers that are divisible are 10, 20, 40 and so on since 5x2=10, 2x5=10; 5x4=20, 2x10=20; 5x8=40, 2x20=40. The least common denominator would be the lowest number which in this case would be 10.

15(2x+2)=10(3x+4) equations with special cases
Answers
Answer:
no solution
Step-by-step explanation:
15(2x+2)=10(3x+4) Distribute.
30x+30=30x+40 Subtract 30x from both sides.
-30x -30x
30=40
30 does not equal 40, so there is no solution.

Find the value of x. Your answer must be exact.
х
45° 18
Answers
Answer:
x = 63
Step-by-step explanation:
Simplifying
x + -18 = 45
Reorder the terms:
-18 + x = 45
Solving
-18 + x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + x = 45 + 18
Combine like terms: -18 + 18 = 0
0 + x = 45 + 18
x = 45 + 18
Combine like terms: 45 + 18 = 63
x = 63
Simplifying
x = 63

=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.

The ratio of ebooks to novels is 4:5. if there are 32 ebooks how many novels are there?
Answers
================================================
Work Shown:
n = number of novels
(32 ebooks)/(n novels) = 4/5
32/n = 4/5
32*5 = n*4 ............ cross multiply
160 = 4n
4n = 160
n = 160/4 .............. dividing both sides by 4
n = 40
There are 40 novels.

BRAINLIEST FOR THE CORRECT AWNSER! Algebra 1 What is the solution to the system of equations graphed below?
Answers
Answer:
(-2, 3)
Step-by-step explanation:
The solution to a system of equations is the value (or values) of x and y that satisfy both equations. we can find the value of x by setting the right sides of each of our equations equal to each other and solving:
[tex]4x+11=-2x-1\\6x=-12\\x=-2[/tex]
From here, we can simply substitute -2 for x in either of the equations to calculate y. I'll choose the bottom one:
[tex]y=-2(-2)-1\\y=4-1\\y=3[/tex]
So our solution is (-2, 3).

you can't find the exact angle with the given info so option 1 is automatic out, m<1 is also clearly an obtuse angle so it will be larger then 90° so option 2 is out, and like I said before m<1 has to be larger then 90° so its not option 3 leaving only option 4
X-y=0 and 5x-2y=6 solve by elimination

first take x-y=0 and multiply it by -5 you will then get this
-5x+5y=0
5x-2y=6

3y=6
divide by 3
y=2
now plug 2 in for y
x-2=0
add 2 to both sides
x=2
if w varies jointly as x and y,
and w=10 when x=2 and y=1.
Solve for w when x=4 and y=2
Answers
Given:
w varies jointly as x and y.
w=10 when x=2 and y=1.
To find:
The value of w when x=4 and y=2.
Solution:
w varies jointly as x and y.
[tex]w\propto xy[/tex]
[tex]w=kxy[/tex] ...(i)
Where, k is the constant of proportionality.
w=10 when x=2 and y=1.
[tex]10=k(2)(1)[/tex]
[tex]10=2k[/tex]
[tex]\dfrac{10}{2}=k[/tex]
[tex]5=k[/tex]
The value of k is 5.
Putting k=5 in (i), we get
[tex]w=5xy[/tex]
To find the value of w when x=4 and y=2. Put x=4 and y=2.
[tex]w=5(4)(2)[/tex]
[tex]w=40[/tex]
Therefore, the value of w is 40 when x=4 and y=2.

KEVI is an isosceles trapezoid.
If KN 10, NV = x, and IE = 2x+6,
what is the length of KV?
Answers
Answer:
14
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.
An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.
From the question:
KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)
From line segment addition postulate:
KV = KN + NV
substituting:
2x + 6 = 10 + x
2x + 6 - x = 10
x + 6 = 10
x = 10 - 6
x = 4
KV = 2x + 6
substituting x = 4:
KV = 2(4) + 6
KV = 14
