Answer:
(x, y) = (2, 3)
Step-by-step explanation:
The first step is to find the least common multiple of the denominators of each of the equations. If the denominators have no common factors, a reasonable choice is their product. Here, it works to start with the fractions that must be added, then compare the LCM found to the denominator on the right to see if any further factors must be included.
First equation:
LCM = 3×4 = 12
12(2x/3 -y/4) = 12(7/12) . . . . . multiply the equation by 12
8x -3y = 7 . . . . . . . . . simplify
Second equation:
LCM = 4×5 =20
20(3x/4 -2y/5) = 20(3/10) . . . . multiply equation by 20
15x -8y = 6 . . . . . . simplify
Solve by elimination
We can eliminate the y-variable by subtracting 3 times the second equation from 8 times the first:
8(8x -3y) -3(15x -8y) = 8(7) -3(6)
19x = 38 . . . . . simplify
x = 2 . . . . . . . divide by 19
Substituting into the first equation gives ...
8(2) -3y = 7
3y = 9 . . . . . . add 3y-7
y = 3 . . . . . divide by 3
The solution is ...
(x, y) = (2, 3)
_____
There are many ways to solve such a system of equations. Using the LCM to eliminate fractions is one way to start. You can also do the arithmetic with the fractions intact, though most folks don't care to. In addition to the elimination method used here, you can use matrix or graphical methods, substitution, or any of the variations of Cramer's Rule.

Find the Value of X (in this picture)
9514 1404 393
Answer:
x = 64
Step-by-step explanation:
The two base angles in the isosceles obtuse triangle are equal, so are both 29°. The sum of these angles is 58°, which is the measure of the external acute angle at the upper left of the acute triangle.
The two base angles of the acute isosceles triangle are equal, so are both 58°. The angle marked x° has a measure that makes the sum of angles in that triangle be 180°.
x° = 180° -2(58°)
x° = 64°
A puppy named Dusty started out at 2 pounds and gained 1 pound every month. At
how many months did Dusty weigh 6 pounds?
Answer:
4 months
Step-by-step explanation:
Let x be the number of months
Dusty started at 2 lbs, and gains 1 lb every month
So we can make the equation
2+x=6
x=4
At 4 months, Dusty was 6 lbs

In the diagram, Find the value of w
Answer:
-13
Step-by-step explanation:
the angle of ACD is 180-72 = 108 degrees.
simply because every side of a line represents 180 degrees of turning potential (to flip something around on a flat ground is a 180 degree turn). and we know 72 degrees are already "taken" at the other side of the angle.
BC bisects the angle. that means it divided the angle into 2 equal parts.
so the angle between BC and k is 108/2 = 54 degrees.
because j is parallel to k, this angle is the same as the angle between BC and j.
so,
54 = 2w + 80
-26 = 2w
w = -13

Solve this equation 2n-9<25
Answer:
n < 17
Step-by-step explanation:
2n-9<25
Add 9 to each side
2n-9+9<25+9
2n < 34
Divide each side by 2
2n/2 < 34/2
n < 17
Answer:
n < 17
Step-by-step explanation:
Move the constant to the right -hand side and change its sign
2n<25+9
Then add the numbers
2n < 34
Divide both sides of the inequality by 2
so that would be n<17

Keisha's teacher gives her the following information:
• m,n,p,and q are all integers and p= 0 and q=0
•A= m/q and B= n/p
What conclusion can Keisha make?
A: A +B = mp+nq/PQ,so the sum of a rational number and an irrational number is an irrational number.
B: A•B= mp+nq/PQ,so the product of two irrational numbers is an irrational number.
C: A+B= mp + nq/PQ,so the sum of two rational numbers is a rational number.
D: A•B= mp + nq/PQ,so the product of two rational numbers is a rational number.
Answer:
C.
Step-by-step explanation:
Integers are rational numbers.
A + B = m/q + n/p = (mp + nq)/pq

Los principales accionistas de la empresa global zafiro S.A. están interesado en una empresa que representa una importante competencia. Entre los datos de la empresa tiene los siguientes: la planta opera a nivel que oscila entre 80 y 100% de su capacidad. Cuando su nivel de actividad es de 80% los costos variables de fabricación totalizan $180,000,000. A su nivel normal de 90% de la empresa utiliza 40,500 horas de mano de obra directa y tiene costos de fabricación totales de $371,500,000. Determina los costos de fabricación finos y variables al 80 y 100% de su capacidad
Answer:
Los costos de fabricación fijo y variables al 80 y 100% de su capacidad son:
80%: Fijos = $169,000,000.00 Variables = $180,000,000.00
100%: Fijos = $169,000,000.00 Variables = $225,000,000.00
Explicación:
Los costos totales de fabricación (CT) vienen dados por la suma de los costos fijos (CF) y los costos variables (CV), recordando que los costos fijos son aquellos en los que se incurre independientemente de que se esté operando o no; mientras que los costos variables son aquellos que dependen del nivel de actividad pues corresponden a consumibles en el proceso productivo.
En el caso estudio, se sabe que los costos variables de fabricación totalizan $180,000,000.00 al nivel de actividad de 80%. Ya que estos costos incrementan o disminuyen en relación con el nivel de actividad, planteamos una regla de tres simple para calcular los costos variables en los niveles de actividad 90% y 100%
Si al 80% de actividad ---------------- los CV son $180,000,000.00
al 90% de actividad ---------------- los CV serán x
x = [(90)(180,000,000.00)]/(80) = 202,500,000.00
Los costos variables de fabricación al nivel de actividad de 90% son $202,500,000.00
Si al 80% de actividad ---------------- los CV son $180,000,000.00
al 100% de actividad ---------------- los CV serán x
x = [(100)(180,000,000.00)]/(80) = 225,000,000.00
Los costos variables de fabricación al nivel de actividad de 100% son $225,000,000.00
Para conocer los costos fijos basta recordar que al nivel de actividad de 90% lo costos de fabricación totales son $371,500,000.00. Este monto es la suma de los costos fijos y los costos variables; así que:
CT = CV + CF ⇒ CV = CT - CF ⇒
CV = 371,500,000.00 - 202,500,000.00 = 169,000,000.00
Los costos fijos de fabricación son de $169,000,000.00
Conclusión:
Los costos de fabricación fijo y variables al 80 y 100% de su capacidad son:
80%: Fijos = $169,000,000.00 Variables = $180,000,000.00
100%: Fijos = $169,000,000.00 Variables = $225,000,000.00
Find the value of the polynomial 3x
3 – 4x
2+ 7x + 5, when x = 3 and also when
x = –3.
Answer:
71
-133
Step-by-step explanation:
Given the polynomial :
3x³– 4x² + 7x + 5, when x = 3 and also when
x = –3.
Put x = 3
3(3)³– 4(3)² + 7(3) + 5
3(27) - 4(9) + 21 + 5
81 - 36 + 21 + 5
= 71
Put x = - 3
3(-3)³– 4(-3)² + 7(-3) + 5
3(-27) - 4(9) - 21 + 5
-81 - 36 - 21 + 5
= - 133
Solve for x.
-15x + 60 ≤ 105 AND 14x + 11 ≤ -31
Choose 1 answer:
A. x ≤ -3
B. x ≥ -3
C. x = -3
D. There are no solutions
E. All values of x are solutions
Answer:
C. x = -3
Step-by-step explanation:
-15x + 60 <= 105
-15x <= 45
-x <= 3
x >= -3
14x + 11 <= -31
14x <= -42
x <= -3
the only solution that is in both solution areas is x = -3.
for all other values of x we violate one of the 2 conditions.

due in 5 years and 3 months?
Answer:
6,825
Step-by-step explanation:
The principlal is #65,000
Rate, = 2%
= 2/100
= 0.02
Time= 5+0.25
= 5.25
Simple interest= 65,000×0.02×5.25
= 6,825

the product of -3 and m increased by 7 is -20. what is the value of m?
Answer:
The value of m is 9.
Step-by-step explanation:
We need to set up an algebraic equation, then solve.
(-3 * m) + 7 = -20
-3m + 7 = -20
Subtract 7 from both sides so we can get -3m by itself. We are isolating it.
-3m + 7 - 7 = -20 - 7
-3m = -27
Divide by -3 on both sides.
m = 9
The value of m is 9.
