How do I solve 1/2x = 4/5 + 1/4x
Answer:
take 1/4 to the other side since 1/2 and 1/4 are like terms then solve for X getting 16/5 as the answer
Have a wonderful time
Solve for x:
(x + 4) (x - 3) = 0
A. x = -4 and x = 3
B. x= -1 and x = 12
C. x= 1 and x = -12
D. X= 4 and x = -3
Answer:
answer is A x = -4 and x = 3
Step-by-step explanation:
-4 , 3
switch the signs
Answer:
The answer is "A."
Step-by-step explanation:
x+4=0. x-3=0
x=0-4. x=0+3
x= -4. x= 3
x = -4 and x = 3

Sarah's grandmother has a square blanket that covers an area of 25 square feet. Sarah wants to put a string of pearls around the sides of the blanket. How many feet long will the string of pearls have to be for Sarah to complete the job?
Answer:
20 ft
Step-by-step explanation:
area of square = (side)^2
area of square = 25 ft^2
(side)^2 = 25 ft^2
side = 5 ft since (5 ft)^2 = 25 ft^2
The side of the square measures 5 ft.
All around the square is the perimeter.
perimeter = 4 * side
perimeter = 4 * 5 ft
perimeter = 20 ft
Answer: 20 ft
the GCF of 30m^4 and 36m^6 is 6m^?
the missing exponent is ____
9514 1404 393
Answer:
4
Step-by-step explanation:
The exponents of m in the two terms are 4 and 6. The exponent of the common factor can be no greater than the smallest of these. (It is the smallest of these.)
GCF(30m^4, 36m^6) = 6m^4 . . . . exponent is 4
Write a quadratic equation in STANDARD FORM given the roots:
1, 1/2
Answer:
f(x) = 2x^2 - 3x + 1
Step-by-step explanation:
The root 1 is associated with the factor (x - 1).
The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)
The quadratic in question is f(x) = (x - 1)(2x - 1). To write this in standard form, perform the indicated multiplication:
f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1
What is the GCF of (4+16) using the distributive property?
Answer:
20
Step-by-step explanation:
The GCF of 4 and 16 is 4.
[tex] \frac{4}{4} = 1 [/tex]
[tex] \frac{16}{4} = 4 [/tex]
We can rewrite this using the distribute property like so:
[tex] 4(1 + 4)[/tex]
Using the distribute property:
[tex] = 4 + 16[/tex]
[tex] = 20[/tex]
We can also add inside the parentheses and multiply we'll get the same answer.
[tex] = 4(5) \\= 20[/tex]

The length and breadth of the plot in metres are in the ratio 10:3.The perimeter
of the plot is 312 m.
Answer:
I hope this could be of good assistant
Step-by-step explanation:
L:B = 10:3
make L subject of formula
L = 10B/3
perimeter = 312
2( L + B ) = 312
L + B = 312/2
L + B = 156
10B/3 + B = 156
multiply all through by 3
10B + 3B = 156 X 3
10B + 3B = 468
13B = 468
B = 468/13 = 36
B = 36m
L = 10B/3
L = 10 X 36/3
L = 10 X 12 = 120m
L = 120m
Hence if your were asked to find the area
L X B
120 X 36 = 4320m²

hello there
im looking for some help here thanks.
Answer:
divide 2 by 9
the result is 0.2 (repeats so need a bar over the 2) is a repeating decimal.
divide 3 by 10
the result is 0.3, is a terminating decimal.
both are rational and real numbers
Answer:
To change 2/9 to a decimal, divide 2 by 9.
The result, 0.222..., is a repeating decimal.
To change 3/10 to a decimal, divide 3 by 10.
The result, 0.3, is a ____ decimal. (I don't know the answer choices, but it would be the one that is the decimal not repeating).
Both 2/9 and 3/10 are irrational numbers.

The angles with measures x and (4x) are complementary angles.
Which is the value of x?
Answer:
x = 18
Step-by-step explanation:
Complementary means the angles add to 90
x + 4x = 90
5x = 90
5x/5 = 90/5
x = 18
The larger angle is 4*18 = 72
5. Suppose a set of math test scores is normally distributed with a mean of 100 (you do not need to know the standard deviation to answer this question, but you may find it helpful to plug in a standard deviation of your choice). If you randomly select a sample of scores from this distribution, which of the following probabilities is higher? Explain your answer.
a. The probability of the sample mean falling between 100 and 105 with a sample of 25 scores.
b. The probability of the sample mean falling between 100 and 105 with a sample of 36 scores.
Answer:
A
Step-by-step explanation:
It is more likely because there is less of a chance of an outlier. Hope this helps.

Write 41 and 4 as a mixed number
Answer:
Numerator. This is the number above the fraction line. For 41/4, the numerator is 41.
Denominator. This is the number below the fraction line. For 41/4, the denominator is 4.
Improper fraction. This is a fraction where the numerator is greater than the denominator.
Mixed number. This is a way of expressing an improper fraction by simplifying it to whole units and a smaller overall fraction. It's an integer (whole number) and a proper fraction.

Answer:
[tex]- 5 {x}^{3} - {x}^{2} - 11x + 7 \\ [/tex]
Step-by-step explanation:
Before solving that we have to know that,
[tex]( + ) \times ( + ) = ( + ) \\ ( - ) \times (- ) = ( + ) \\ ( + ) \times ( - ) = (- )[/tex]
Let's solve now.
[tex]7 {x}^{3} - 11x - 1 - (12 {x}^{3} + {x}^{2} - 8) \\ 7 {x}^{3} - 11x - 1 - 12 {x}^{3} - {x}^{2} + 8 \\ 7 {x}^{3} - 12 {x}^{3} - {x}^{2} - 11x - 1 + 8 \\ = - 5 {x}^{3} - {x}^{2} - 11x + 7[/tex]

Answer:
Distributive property, Inverse Operation, and Division property of Equality
Step-by-step explanation:
Because 8•x is 8x and 8x3 is 24 so then the equation would be 8x-24=-40 then you have to add 24 on both sides to the 8x by itself and also get -16 which you would divide 8 on both sides to get x= -2
