expression: 20 - n
total balloons = 20popped balloons = nnumbers of balloons left = total balloons - popped balloons
numbers of balloons left = 20 - n
Answer:
20 - n balloons remained
Explanation:
To find how much balloons remained after the party, we need to subtract the number of balloons popped from the total balloons.Finding how much balloons remained:
We know that there were 20 balloons at the beginning of the party and n balloons popped when the party was over.20 - n balloons remained.

x + 17 = -2x + 23
what is the answer to this ? and show me the work please
Answer:
2
Step-by-step explanation:
[tex]x + 17 = - 2x + 23 \\ \\ x + 2x = 23 - 17 \\ \\ 3x = 6 \\ \\ x = \frac{6}{3} \\ \\ x = 2[/tex]
Answer:
x = 2
Step-by-step explanation:
First, we will move all the xs to one side and everything else to the other side.
x + 17 = -2x + 23
+2x +2x
-17 -17
This gives us:
x + 2x = 23-17
Then we can just combine like terms:
3x = 6
And divide both sides by three:
x = 2

Un grupo de 25 estudiantes aportará $4.00 cada uno, para comprar una pizarra.
Si se reduce la cantidad de estudiantes a 20, ¿cuál será el aporte de cada
estudiante para comprar la pizarra?
Usando algebra, veremos que cada estudiante debe aportar $5.00.
¿Cuál será el aporte de cada estudiante?
En el caso en el que hay 25 estudiantes, cada uno aporta $4.00, entonces la cantidad total que se colecta es:
25*$4.00 = $100
Ahora, en el caso de que hay 20 estudiantes, cada uno aportara una cantidad x, de tal forma que:
20*x = $100
Debemos resolver la ecuación de arriba para x:
x = $100/20 = $5.00
Es decir cada estudiante debe aportar $5.00

9g − g + 4g − 8g − 2 = 18
plz
Answer:
g = 5
Step-by-step explanation:
Combine like terms on the left side.
9g - g + 4g -8g = 4g
4g - 2 = 18
Add 2 to both sides.
4g = 20
Divide both sides by 4.
g = 5

An alloy is composed of nickel, zinc, and copper in a 5:4:8 ratio. How many kilograms of each metal is needed to make 3.4 kg of this alloy?
Answer:
1 kg, 0.8 kg, 1.6 kg
Step-by-step explanation:
Add up each part in the ratio
5 + 4 + 8 = 17
Divide the mass of the alloy by 17
3.4/17 = 0.2
To find out how much of each metal is in the alloy multiply 0.2kg by how many parts of it are in the alloy.
Nickel - 5 parts
0.2 x 5 = 1 kg
Zinc - 4 parts
0.2 x 4 = 0.8 kg
Copper - 8 parts
0.2 x 8 = 1.6 kg
Answer:
Step-by-step explanation:
5x+4x+8x=3.4
17x=3.4
x=0.2
Nickel 1 kg
Zinc 0.8 kg
Copper 1.6 kg

Find the Pattern
12 ↦ −1
3 ↦ −4
0 ↦ −5
−1 ↦ −5.3…
−9 ↦ −8
I have to find a formula to get from the left number to the right number, but I cannot find the pattern. How do I do this, and what is the solution?
Answer: y = (1/3)x - 5
This is the same as writing [tex]y = \frac{1}{3}x-5[/tex]
======================================================
Explanation:
Assume we have a linear pattern matching the form y = mx+b.
The first row has x = 12 lead to y = -1
The second row has x = 3 lead to y = -4
This produces the two points (12,-1) and (3,-4)
Let's find the slope through those points.
m = (y2-y1)/(x2-x1)
m = (-4-(-1))/(3-12)
m = (-4+1)/(3-12)
m = -3/(-9)
m = 1/3
The slope is 1/3.
The y intercept is b = -5 since x = 0 leads to y = -5
We go from y = mx+b to y = (1/3)x - 5
--------------------------
To verify we have the correct equation, plug in each left side value as x values.
Let's try x = 12
y = (1/3)x - 5
y = (1/3)*12 - 5
y = 4 - 5
y = -1
This shows that the input x = 12 maps to the output y = -1
i.e. 12 ↦ −1 is the case here.
Repeat for x = 3
y = (1/3)x - 5
y = (1/3)*3 - 5
y = 1 - 5
y = -4
We can see that 3 ↦ −4 occurs.
I'll let you check the others, but you should find that the other mappings hold true as well. Therefore, the answer has been fully confirmed.
