Explain why these two equations are different
5(x+4)=60 and 5x+4=60
Step-by-step explanation:
When you use the distributive property, you multiply everything inside the parentheses by the number outside of the parentheses. When you distribute, the equation becomes 5x+20=60 vs 5x+4= 60. Hope this helps!

2 people can paint a fence in one hour. How long would it take 10 people? Please answer in minutes :)
Answer:
12 minutes
Step-by-step explanation:
We must understand that as the number of people increase in a work, lesser time is taken to finish the work. This implies that the number of people is inversely proportional to the time taken to do the work.
Let n be the number of people.
Let t be the time taken to do the work.
Thus,
n ∝ 1/t
n = K/t
Next, we shall determine the constant of proportionality. This can be obtained as follow:
Number of people (n) = 2
Time (t) = 1 h = 60 minutes
Constant of proportionality (K) =.?
n = K/t
2 = K / 60
Cross multiply
K = 2 × 60
K = 120
Finally, we shall determine the time taken for 10 people to do the work. This can be obtained as follow:
Number of people (n) = 10
Constant of proportionality (K) = 120
Time (t) = ?
n = K/t
10 = 120 / t
Cross multiply
10 × t = 120
Divide both side by 10
t = 120 / 10
t = 12 minutes
Thus, it will take 12 minutes for 10 people to finish the work.

In how many ways can coach Lewis select 5 young women for the basketball team if 15 players try out?
Given:
Total number of players = 15
Required players = 5
To find:
The number of ways to select 5 young women for the basketball team if 15 players try out?
Solution:
We know that, the total number of ways to select r items from n item is
[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
The total number of ways to select 5 players from 15 is
[tex]^{15}C_5=\dfrac{15!}{5!(15-5)!}[/tex]
[tex]^{15}C_5=\dfrac{15\times 14\times 13\times 12\times 11\times 10!}{5\times 4\times 3\times 2\times 1\times 10!}[/tex]
[tex]^{15}C_5=\dfrac{15\times 14\times 13\times 12\times 11}{5\times 4\times 3\times 2\times 1}[/tex]
[tex]^{15}C_5=3\times 7\times 13\times 11[/tex]
[tex]^{15}C_5=3003[/tex]
Therefore, coach Lewis can select 5 young women from 15 in 3003 ways.
Alfred owns land that has an area of x²-25. His neighbor Grace is selling him the land she owns so he can combine them into one big property. Her land has an area of x²+3x+2. PART A-4pts Factor the expressions that represent Alfred's land and Grace's land to find the Dimensions of each property.
Answer:
Step-by-step explanation:
Area of Alfred's land = (x²- 25)
Factors of given expression = (x - 5)(x + 5)
Therefore, Alfred's land will have the dimensions (x - 5) and (x + 5).
Area of his neighbor's land = x² + 3x + 2
Factors of the given expression = x² + 2x + x + 2
= x(x + 2) + 1(x + 2)
= (x + 1)(x + 2)
Therefore, dimensions of Grace land will be (x + 1) and (x + 2).

Dividir 254 en tres partes tales que la segundasea el triplo de la primera y 40 unidades mayor que la tercera
Responder:
x = 40
y = 120
z = 80
Explicación paso a paso:
Número dividido = 240
Las 3 partes:
x, y, z
y = 3x
Z = 3x - 40
x + y + z = 240
x + 3x + 3x - 40 = 240
7x - 40 = 240
7x = 240 + 40
7x = 280
x = 280/7
x = 40
y = 3 (40)
y = 120
z = 3x - 40
z = 3 (40) - 40
z = 120 - 40
z = 80
