- -4(-3n - 8) = 104
Divide both sides by -4!
-4(-3n - 8) over -4 = 104/-4
Simplify!
-3n - 8 = -26
Add 8 to both sides!
-3n - 8 + 8 = -26 + 8
Simplify!
-3n = -18
Divide both sides by -3!
-3n/-3 = -18/-3
Simplify!
n = 6

invertimos el orden de dichas cifras, el número obtenido es 36 unidades mayor que
el inicial.
porfavor es para mañana
Answer:
A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla
entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100
en mi primera ecuación seria: 4X + 3Y = 14.100
ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla
en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:
primera ecuación: 4X + 3Y = 14.100
segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1
al sumarlas obtengo como resultado: -5X = -12
resolviendo esa ecuacion obtengo que X=
X=2.4
luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100
reemplazando seria: 4 x (2.4) + 3Y =14.100
9.6 + 3Y = 14.1000
3Y= 14.100 - 9.6
Y=
Y=1.5
entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

subtract 16 from both sides:
3x = 39
divide 3 to both sides:
x= 13

-2x – 6y = -24
X-8y = -10
Answer:
{x,y}={31,4}
Step-by-step explanation:
x-8y = -1 x-6y = 7
Answer:
first we find the value of 'y' so
x-8y=-10+8y
x=-10+8y
-2(-10+8y)-6y=-24
20-16y-6y=-24
20-22y=-24-20
-22y=-44
y=2
then also we can find the value of 'x'
-2x-6y=-24
2x-6(2)=-24
2x-12= -24
2x= -24+12
x= -12

Your parents gave you $20 to spend at the book fair. You are getting the new Diary of the Wimpy kid book that costs $8.99/ If pencils and erasers cost $0.79 each, what is the maximum you can buy with the money provided?
Answer:
You can buy a maximum of 13 erasers/pencils.
Step-by-step explanation:
Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

What is 35a + 14 = 1
Answer:
a = -13/35
Step-by-step explanation:
35a + 14 = 1
(given)
_________
35a + 14 = 1
- 14 -14
(subtraction property of equality)
(subtract 14 from both sides to isolate the 35a term)
_________
35a = -13
÷35 ÷35
(division property of equality)
(divide by 35 on both sides to remove the coefficient of 35 in 35a)
_________
a = -13/35
35a+14=1
35a+14 - 14 = 1 - 14
35a= -13
35a= -13
35a = -13
35 35
a= -13/35

= 5,136 / 210
= 24 months approximately.

granola evenly among 4 friends. How much granola did
each friend get?
Answer:
Step-by-step explanation:
So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.
(3/5) / 4
Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.
So (3/5) * (1/4) is 3/20 which is .15 pounds

Answer:
2 x ? = 7 1/2 and ? x 2 = 7 1/2
Step-by-step explanation:
This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.

Which ratio is the simplest form of 68:84?
A 2:3
17:21
34:42
D 21:17
Answer:
17:21
Step-by-step explanation:
The ratio 68:84 in its simpliest form is;
68:84 (Since it can divided by 2 perfectly);
34:42 (We also divide this by 2 )
17:21
17:21 is the final answer and it can be divide any further. Since 17 is a prime number, it can't be divided and also 21 can be divided by 3 but 17 can't be divided by 3 so we leave the final answer like that.
