Adding and subtracting fractions with different denominators :D
Answer:
find the LCM of denominators and multiply the last answers of LCM for example take 1/3 and 1/2 it's LCM is 6
1/3 = 1×2/3×2 = 2/6
1/2 = 1×3/2×3 = 3/6
then subtract 3-2/6 = 1/6 this is subtraction
instead of subtracting just add it

Step-by-step explanation:
Subject: Re: Need the math proof for 1 + 1 = 2
The proof starts from the Peano Postulates, which define the natural
numbers N. N is the smallest set satisfying these postulates:
P1. 1 is in N.
P2. If x is in N, then its "successor" x' is in N.
P3. There is no x such that x' = 1.
P4. If x isn't 1, then there is a y in N such that y' = x.
P5. If S is a subset of N, 1 is in S, and the implication
(x in S => x' in S) holds, then S = N.
Then you have to define addition recursively:
Def: Let a and b be in N. If b = 1, then define a + b = a'
(using P1 and P2). If b isn't 1, then let c' = b, with c in N
(using P4), and define a + b = (a + c)'.
Then you have to define 2:
Def: 2 = 1'
2 is in N by P1, P2, and the definition of 2.
Theorem: 1 + 1 = 2
Proof: Use the first part of the definition of + with a = b = 1.
Then 1 + 1 = 1' = 2 Q.E.D.
Note: There is an alternate formulation of the Peano Postulates which
replaces 1 with 0 in P1, P3, P4, and P5. Then you have to change the
definition of addition to this:
Def: Let a and b be in N. If b = 0, then define a + b = a.
If b isn't 0, then let c' = b, with c in N, and define
a + b = (a + c)'.
You also have to define 1 = 0', and 2 = 1'. Then the proof of the
Theorem above is a little different:
Proof: Use the second part of the definition of + first:
1 + 1 = (1 + 0)'
Now use the first part of the definition of + on the sum in
parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.

A. Write an expression to represent the difference between the two points shown on the number line.
B. Find the distance between the two points. [Hint: Remember that distance is always positive.]
Part A
distance of point 1 = -1.6
distance of point 2 = 0.3
difference: -1.6 - 0.3 = -1.9
distance: 0.3-(-1.6) = 1.9
The expression that represents the distance between the two points is |0.3 + 1.6| and the distance between the two points is 1.9 units
The expression of the distanceThe points on the line are represented as:
Point 1 = 0.3
Point 2 = -1.6
The distance between the two points is calculated using the following absolute value equation
d = |Point 1 - Point 2|
Substitute the known values
d = |0.3 - -1.6|
This gives
d = |0.3 + 1.6|
Hence, the expression that represents the distance between the two points is |0.3 + 1.6|
Evaluate the expressionIn (a), we have:
d = |0.3 + 1.6|
Evaluate the sum
d = |1.9|
Remove the absolute sign
d = 1.9
Hence, the distance between the two points is 1.9 units

In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether the proportions have changed, a random sample of 300 students from ABC University was selected. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. Refer to Exhibit 12-4. This problem is an example of a _____. a. multinomial population b. normally distributed variable c. uniformly distributed variable
Answer:
A. Multinomial population
Explanation:
A multinomial population has categorical data. In other words data in this form has different classes in which data is grouped into. These classes do not overlap and are more than two as opposed to binomial populations that have just two outcome variables or data categories. For example in the above data, we see that data is grouped into three categories:students in business college, students in liberal art college and students in education college

Write the equation of the graph.
y=1/2x+5
y−3=−1/2(x+1)
y−3=1/2(x+1)
y+3=−1/2(x−1)
Answer:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Combine 32 3 2 and x x . Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 32 .
Step-by-step explanation:
Lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase right angle is 110 degrees. At the intersection of lines b and e, the uppercase right angle is 110 degrees. At the intersection of lines b and f, the bottom right angle is 80 degrees.
Which lines are parallel? Justify your answer.
Lines a and b are parallel because their corresponding angles are congruent.
Lines a and b are parallel because their same side exterior angles are congruent.
Lines e and f are parallel because their corresponding angles are congruent.
Lines e and f are parallel because their same side exterior angles are supplementary.
Answer:
D. Lines e and f are parallel because their same side exterior angles are supplementary.
Step-by-step explanation:
I know for a fact that it is not C or A even though those ones would make the most sense. This leaves B and D; It's not B because is said that angles A and B are both exterior which is incorrect, A in interior and B is Exterior. This leaves us with D as our final answer.
Hope this helps, may I get brainliest please? :)
The parallel lines are; Lines e and f are parallel because their same side exterior angles are supplementary.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 4x + 2, thus its slope is 4 and thus, the slope of the needed line is 4.
We have given that Lines e and f are intersected by lines a and b.
At the intersection of lines a and e, the uppercase right angle is 110 degrees. The lines b and e, the uppercase right angle is 110 degrees. The lines b and f, the bottom right angle is 80 degrees.
Therefore, The parallel lines is; Lines e and f are parallel because their same side exterior angles are supplementary.

The slope-intercept form of the equation of a line that passes through point (–3, 10) is y = 2x + 16. What is the point-slope form of the equation for this line?
(A): y -3 = 2 (x +10)
(B): y +3 = 2 (x -10)
(C): y + 10 = 2 (x - 3)
(D): y - 10 = 2 (x + 3)
Answer:
D

the equation would be D bc using the point given u can fill out the equation y-y1=m(x-x1) so it would be y-10=m(x-(-3). then fill in slope and change the (x-(-3) into x+3. The equation is now y-10=2(x+3).

A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed. explain your reasoning
Hurry please I need it ASAP!!
Find the required table attached
Since the speed of the Cheetah is constant, this means that the speed must be the same all through in the table.
To get the unknown time and distance, we will have to use the formula below:
Speed = Distance/Time = kWhen distance = 120m, time = 4secsSpeed = 120/4 = k
Speed = 30m/s = k
We are to get the distance when the time is 25secs
Speed = Distance/Time
30 = d₂/25
d₂ = 30 × 25
d₂ = 750 m
To get the time in the third column
Time = Distance/Speed
