Answer:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]
Step-by-step explanation:
Given the expression
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}[/tex]
Group like terms
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}=-4n+4n+\frac{1}{3m}-\frac{4}{5m}[/tex]
Adding similar elements: -4n + 4n = 0
[tex]=\frac{1}{3m}-\frac{4}{5m}[/tex]
L.C.M of 3m and 5n will be: 15m
so adjusting fractions based on the LCM
[tex]=\frac{5}{15m}-\frac{12}{15m}[/tex]
Since, the denominators are equal, combine the fractions: [tex]\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{5-12}{15m}[/tex]
[tex]=\frac{-7}{15m}[/tex]
[tex]=-\frac{7}{15m}[/tex]
Therefore, we conclude that:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]
In the equation 5x-2=-x-20, What is the value of x?
a. 2
b. -1
c. -3
d. -2
Answer:
C choice.
Step-by-step explanation:
[tex]5x - 2 = - x - 20 \\ [/tex]
First, we move the same terms to the same side.
[tex]5x + x = - 20 + 2 \\ 6x = - 18[/tex]
Then we move 6 to divide - 18.
[tex]x = \frac{ - 18}{6} \\ x = - 3[/tex]

Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei, iar 3 kg de nectarine şi 9 kg de piersici costă 54 de lei, află cât costă un kilogram de nectarine şi cât costă un kilogram de piersici.
Answer:
Costul unui kilogram de nectarine = x = 6 lei
Costul kilogram de piersicilor = y = 4 lei
Step-by-step explanation:
Lăsa
Costul nectarinelor = x
Costul piersicilor = y
Prin urmare:
Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei
4x + 6y = 48 .... Ecuația 1
3 kg de nectarine și 9 kg de piersici costă 54 de lei
3x + 9y = 54 .... Ecuația 2
Combinând ambele ecuații
4x + 6y = 48 .... Ecuația 1
3x + 9y = 54 .... Ecuația 2
Rezolvăm folosind metoda Eliminare
Înmulțiți ecuația 1 cu 3 și ecuația 2 cu 4 pentru a elimina x
12x + 18y = 144 .... Ecuația 3
12x + 36y = 216 ... Ecuația 4
Scădeți ecuația 4 din 3
-18y = -72
y = -72 / -18
y = 4 lei
Pentru a rezolva pentru x: y = 4
4x + 6y = 48 .... Ecuația 1
4x + 6 × 4 = 48.
4x + 24 = 48
4x = 48 - 24.
4x = 24
x = 24/4
x = 6 lei
Prin urmare:
Costul unui kilogram de nectarine = x = 6 lei
Costul kilogram de piersicilor = y = 4 lei

How to convert To prepare for a bake-off, Louise used 0.61 kilogram of flour each day for 3 weeks. How many grams did Louise use in those 3 weeks? 1 kg = 1,000 g
Given:
Louise used 0.61 kilogram of flour each day for 3 weeks.
To find:
How many grams did Louise use in those 3 weeks?
Solution:
We know that,
1 kg = 1000 g
Flour used by Louise each day for 3 weeks = 0.61 kg
1 week = 7 days
3 week = 21 days
Flour used by Louise for 3 weeks (21 days) = (21 × 0.61) kg
= 12.81 kg
= (12.81 × 1000) [ 1 kg = 1000 g]
= 12810 g
Therefore, flour used by Louise for those 3 weeks is 12,810 grams.
In a box of chocolates, 1/5 of the chocolates contain nuts.
The rest of the chocolates do not contain nuts.
Write down the ratio of the number of chocolates that contain nuts to number of chocolates that do not contain nuts.
Give your answer in the form of 1:n
Answer:
1:4
Step-by-step explanation:
Ratios and Fractions
It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:
[tex]1 - \frac{1}{5}=\frac{4}{5}[/tex]
We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.
This can be done by dividing 1/5 by 4/5:
[tex]\displaystyle \frac{\frac{1}{5}}{\frac{4}{5}}[/tex]
Operating:
[tex]\displaystyle \frac{1}{5}\cdot\frac{5}{4}=\frac{1}{4}[/tex]
Expressing it as a ratio: 1:4

Missing Angles in Triangles Worksheet
I need help with everything on this sheet (A-U) please and thank you.
Answer:
Step-by-step explanation:
This question is based on the angles of the triangle.Therefore, the angles of the triangle is 180 degree.
We need to determined the all the angles of triangle in the figure.
In the triangle ABC,
All sides are equal, therefore it is equivalent triangle. Hence, all angles are also equal.
Therefore, angle A = 60 degree, angle B = 60 degree, angle C = 60 degree.
Now, find the angle N.
In triangle PAN, one of the angle is 69 degree, and the other is 90 degree.
We know that,
Sum of angles of the triangle is 180 degree.
Thus, angle N = 180-69-90
Angle N = 21 degree
From the figure, it is observe that,
Angle P = 90 -69 = 21 degreeAngle O = 90 - angle N = 90 - 21 = 69 degree.Angle R = 90 degree - 15 = 75 degreeAngle Q = 90- 15 = 75 degreeAngle S = 90 - 48 = 42 degreeAngle T = 180- 48-90 = 42 degreeAngle J = 180 - 75 - 90 = 15 degreeAngle L = 180 - 15 - 90 = 75 degreeAngle H = 180 - 75- 60 = 45 degreeAngle I = 90 - 45 = 45 degreeAngle M = 180 - 60 = 120 degreeAngle K = 180 - 120 - 45 = 15 degreeAngle E = 90 - 55 =35 degreeAngle G= 180 - 35 - 90 =55 degreeAngle F = 90 - 55 = 35 degreeAngle U = 69 degree ( from the figure)Angle D = 180 - 69 - 69 = 42 degreeTherefore, these are the all the angles of the given figure.

An indoor soccer field is a rectangle that is 700 feet long by 250 feet wide. Coach Garza is having his players run diagonally from one corner of the field to the opposite corner. What is the distance the players must run?
Answer: 743.30343766 . . . ft
Round it to whatever place your teacher requires it to be at.
Step-by-step explanation: So, this question can be treated as one in which you need to find the hypotenuse. If you cut the soccer field diagonally, the length and width are still the same. The two legs of our triangle are 700 ft and 250 ft. The formula for finding the hypotenuse is a²+b²=c². Input the numbers, and it becomes 700²+250²=c². 700² is 490,000 and 250² is 62,500. 490,000 + 62,500 = 552,500. This means that 552,500 is c², and in order to find c, or the hypotenuse/diagonal, we need to find the square root of 552,500. The square root of 552,500 is 743.3034376 . . . , which you can round to whatever place you need it to be at.

In a right triangle the measure of one acute angle is 4 times the difference of the measure of the other acute angle and 5. Find the measure of each acute angle
Answer:
The measures are 22 and 68 degrees
Step-by-step explanation:
for a right triangle, the total angle measure gives 90
Let one of the acute angle be x and the other be y
The measure of one of the acute angle is 4 times the the difference of the measure of the other angle and 5
x = 4(y-5)
Also x + y = 90
Put i into ii
4(y-5) + y = 90
4y-20 + y = 90
5y-20 = 90
5y = 90 + 20
5y = 110
y = 110/5
y = 22
But;
x = 4(y-5)
x = 4(22-5)
x = 4(17)
x = 68
The sum of the acute angles in a right-angled triangle is 90.
The acute angles are 22 and 68 degrees
Let the acute angles be x and y, such that:
[tex]\mathbf{y = 4(x - 5)}[/tex]
So, we have:
[tex]\mathbf{x + y = 90}[/tex]
Substitute 4(x - 5) for y
[tex]\mathbf{x + 4(x - 5) = 90}[/tex]
Open brackets
[tex]\mathbf{x + 4x - 20 = 90}[/tex]
Add x and 4x
[tex]\mathbf{5x - 20 = 90}[/tex]
Add 20 to both sides
[tex]\mathbf{5x = 110}[/tex]
Divide both sides by 5
[tex]\mathbf{x = 22}[/tex]
Recall that:
[tex]\mathbf{y = 4(x - 5)}[/tex]
So, we have:
[tex]\mathbf{y = 4(22 - 5)}[/tex]
[tex]\mathbf{y = 68}[/tex]
Hence, the acute angles are 22 and 68 degrees
