2.4x + 4.6x = 28 Could someone help me with this problem I need it.
Answer:
x = 4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define
2.4x + 4.6x = 28
Step 2: Solve for x
Combine like terms (x): 7x = 28Divide 7 on both sides: x = 4Step 3: Check
Plug in x to verify it's a solution.
Substitute in x: 2.4(4) + 4.6(4) = 28Multiply: 9.6+ 18.4= 28Add: 28 = 28Here we see that 28 does indeed equal 28.
∴ x = 4 is a solution of the equation.
A ski club rents cross-country skis. The table below shows the cost of rentals for two and four days. Number 1 2 3 of Days Rented Rental Cost ($) 12 17 22 27 Which explicit formula models the cost of renting skis from the club? o an . = 12 + 5n O an . 10n An = 5 + 5n O an an = 7+5n
Answer:
an = 7 + 5n
Step-by-step explanation:
First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.
We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.
Hence the answer an = 7 + 5n

Kiran has LaTeX: 10\frac{1}{2} 10 1 2 feet of lumber and wants to make a bookshelf. Kiran needs two side panels that are each LaTeX: 5\frac{2}{3} 5 2 3 feet. How much more lumber does Kiran need in order to make the side panels? A) LaTeX: \frac{5}{6} 5 6 feet B) LaTeX: \frac{1}{2} 1 2 feet C) LaTeX: 1\frac{5}{6} 1 5 6 feet D) LaTeX: 1\frac{1}{2} 1 1 2 feet
Answer:
A) LaTeX: \frac{5}{6} 5 6 feet
Step-by-step explanation:
Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.
Kiran needs two side panels that are each 5 2/3 feet.
1 side panel = 5 2/3 feet
2 side panels =
2 × 5 2/3
2 × 17/3
= 34/3
= 11 1/3 feet
Kiran would need 11 1/3 feet of lumber.
Kiran already has 10 1/2 feet
How much more lumber does Kiran need in order to make the side panels?
This is calculated as:
11 1/3 - 10 1/2
11 - 10 + (1/3 - 1/2)
1 + ( 2 - 3/6)
1 + (-1/6)
1 - 1/6
= 5/6
Hence, Kiran need 5/6 feet more of Lumber.

Y=-6x+10. Y=-6x+3
Solve the system of equations
Given:
The system of equations is
[tex]y=-6x+10[/tex]
[tex]y=-6x+3[/tex]
To find:
The solution of given system of equations.
Solution:
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
For [tex]y=-6x+10[/tex], slope is -6 and y-intercept is 10.
For [tex]y=-6x+3[/tex], slope is -6 and y-intercept is 3.
Slopes of both lines are but the y-intercepts are difference. So, the two lines are parallel.
Therefore, the given system of equation has no solution.

There are 14 teams in a basketball league.
Each team plays every other team twice
during the season.
a) Suppose that you want to determine
how many games, in total, are played.
Suggest a simpler problem that you
could solve first.
b) How many games, in total, are played
during the season?
Answer:
Step-by-step explanation:210 games
14+13+12... (x2)
The total number of games played is 182.
What is permutation?The number of possible arrangements for a given set is calculated mathematically using permutation, where the arrangement's order matters.
Given that, there are 14 teams and each team plays twice with the other team.
Since each team plays every other team twice, the total number of games is nothing but the permutation of 2 out of 14 which is given by:
₁₄P₂
=14!/((14-2)!)
= (14×13×12!)/ 12!
= 14×13
=182
Hence, the total number of games played is 182.

The fundraiser actually made $600. What was the percent
error of David's estimate?
Answer:
18%
Step-by-step explanation:
if i am right
it would be subtract 492- 600 = -108
make this a positive value so 108
and divide it by the actual made amount
108/600 which would be 0.18 multiply this by 100 and you have 18% !!
