Step-by-step explanation:
explain how using fraction strips with like denominators makes it possible to add fractions with unlike denominators.
Fraction strips uses (least) common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.
Fraction strips require three major steps.
1. Firstly convert the problem with modelling as fraction strips.
2. Find the common denominator which should be least of all.
3. Now calculate the sum on new converted fractions.
For example:
[tex]\begin{aligned}\dfrac{1}{2} + \dfrac{3}{4} &= \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{3}{4}\\&= \dfrac{2}{4} + \dfrac{3}{4}\\&= \dfrac{5}{4} = \: Ans.\end{aligned}[/tex]

For the functions f left parenthesis x right parenthesis equals 6 minus x squared and g left parenthesis x right parenthesis equals x squared plus 4 x minus 12, find fplusg, fminusg, fg, and StartFraction f Over g EndFraction . Determine the domain for each function.
Answer:
Step-by-step explanation:
Given the functions
F(x) = 6-x²
G(x) = x²+4x-12
A) we are to find F(x)+g(x)
F(x)+G(x) = 6-x²+x²+4x-12
F(x)+G(x) = 6+0+4x-12
F(x)+G(x) = 4x+6-12
F(x)+G(x) = 4x-6
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER
F(x)-g(x) = 6-x²-(x²+4x-12)
F(x)-g(x) = 6-x²-x²-4x+12
F(x)-g(x) = 6-2x²+4x+12
F(x)-g(x) = -2x²+4x+6
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER
3) F(x)/G(x)
= 6-x²/x²+4x-12
The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER

A phone company offers two monthly charge plans. In plan a there is no monthly fee, but the customer pays 8 cents per minute of use. In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use. For what amount of monthly phone use will plan a cost more than plan b? Use m for the number of minutes of phone use in a month and solve your inequality for
Answer:
[tex]m>2.40[/tex]
Step-by-step explanation:
Let m denotes the number of minutes of phone use in a month.
In plan a there is no monthly fee, but the customer pays 8 cents per minute of use.
Total cost of plan a = [tex]8m[/tex]
In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use.
Total cost of plan b = [tex]2.40+7m[/tex]
To find amount of monthly phone use for which plan a cost more than plan b, solve the inequality [tex]8m>2.40+7m[/tex].
[tex]8m>2.40+7m\\8m-7m>2.40\\m>2.40[/tex]

Answer:
c. m∠2 = m∠5
Step-by-step explanation:
We can check 1 by 1 and find the false one.
For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.
For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.
For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.
For answer d, measure 2 and 6 are corresponding angles, so that's also not false.
Therefore, the answer must be c.

Answer:6(-4)
Step-by-step explanation:
Answer:
4(-6), 6(-4), 12(-2)
Step-by-step explanation:
Hi there!
A negative number times a positive number is a negative number. So, since -4 x 6 has one negative number, you can think of it as 4 x 6 and then add a minus sign after multiplying, so -4 x 6 is -24.
In multiplication, no matter which way the equation goes, the answer will always be the same ( 5 x 3 is the same as 3 x 5). Therefore, we are looking for another equation that will also equal -24.
4(-6) is the same because it is still one number that is a negative, and it still equals -24.
6(-4) is the same as well, it's just we're putting the parentheses around the -4 this time.
12 x 2 is 24, so 12(-2) is negative 24 (-24)

3/5 (2m-10)=2/3m+10
Answer:
m = 30
Step-by-step explanation:
3/5 (2m-10)=2/3m+10
Distribute
6/5 m - 6 = 2/3m +10
Subtract 2/3 m from each side
6/5 m - 2/3 m - 6 = 2/3m -2/3m +10
6/5 m -2/3m - 6 = 10
Add 6 to each side
6/5 m -2/3m - 6+6 = 10+6
6/5m -2/3m = 16
Get a common denominator of 15
18/15 m - 10/15 m =16
8/15 m = 16
Multiply each side by 15/8
15/8 *8/15 m = 16*15/8
m = 30

Answer:
107
Step-by-step explanation:
it looks like a right angle
Answer:
The answer is 107 degrees.
Step-by-step explanation:
The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.
