4(x-5)=10(x-10)
solve for x
Answer:
40/3
Step-by-step explanation:
4x -20 = 10x -100 (Distributive Property)
4x -10x = -100 +20 (I swith the numbers so all of them are similar)
-6x= -80 (Divide -6 on both sides)
And you will get 40/3 or 13.3333..
Answer:
x = 40/3
Step-by-step explanation:
4(x-5)=10(x-10)
=> 4x - 20 = 10x - 100
=> 4x - 10x = - 100 + 20
=> -6x = -80
=> x = 80/6
=> x = 40/3

For (triangle)DEF, you are required to construct the median DG to EF. Which of the following must be performed first?
A. Draw EF to DG.
B. Draw DG to EF.
C. Bisect DE at G.
D. Bisect EF at G.
Answer: C. Bisect DE at G.
Step-by-step explanation:
In a triangle, a median is a line segment drawn from a vertex to the midpoint of the opposite side of the vertex.So, for triangle DEF , if we draw the median DG to the opposite side EF.
Here EF is the opposite side to vertex D.
So, G must be the midpoint of line segment EF.
So , we need to first mark G on EF.
i.e. we need to bisect EF at G.
So first step would be : Bisect EF at G.

SF = 7/3
Step-by-step explanation:
Like the problem hint says, you want to put the new coordinate over the old one to find the scale factor. We'll use both x and y.
-7/-3 = 7/3
14/6 = 7/3
Therefore, the scale factor is 7/3.
I NEED HELP WIT MATH!!!!!!!!!!
Answer:
x-intercept= -6 & y-intercept = 8
Step-by-step explanation:
To find the intercepts you just have to put the opposite value as 0 in the equation.
X-intercept:
-4x + 3(0) = 24
Y-intercept:
-4(0) + 3y = 24
Everything times 0 is 0, so it cancels out.
Then it is just simple dividing.
Future reminder:
Just remember this (x,y)
-X-intercept point (?,0)
-Y-intercept point (0,?)
? = any number

Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
Answer:
x = 60°Step-by-step explanation:
Sum of interior angles of a regular polygon is:
180°(n-2)Pentagon has 5 sides, so sum of angles is:
180°(5-2) = 180°*3 = 540°For the given pentagon we have sum of angle measures as below, and solving for x:
x + 2x + 2.5x + (x +10) + (2x + 20) = 540°8.5x + 30° = 540°8.5x = 510°x = 510°/8.5x = 60°There are 50 teens in a work program. The circle graph shows the percentage of workers who have 0, 1, 2, 3, and 4 siblings.

The length of a rectangle is twice the width. An equation that models the perimeter of the rectangle is 2w+4w=36 where w is the width of the rectangle is ft. What are the length and width of the rectangle?
Answer: 12
Step-by-step explanation:
Let w = the width of the rectangle
Let 2w = the length
P = 2l + 2w
36 = 2(2w) + 2w
36 = 4w + 2w
36 = 6w
w = 6
l = 2(6)
l = 12

David works in a department store selling clothing. He makes a guaranteed salary of $250 per week, but is paid a commision on top of his base salary equal to 5% of his total sales for the week. How much would David make in a week in which he made $1500 in sales? How much would David make in a week if he made xx dollars in sales?
Answer:
250 + 0.05 (1500)
250 + 75 = $325 david made i a week with 1500 in sales
250 + 0.05(xx) is how much david would make if he sold xx that week
Step-by-step explanation:
i hope this helped :)
A linear function is a function that changes at a constant rate.
David would make $325 if he made $1500 in sales,He would make 250 + 0.05x if he made $x in salesThe given parameters are:
Flat Salary = $250 weeklyCommission= 5%A linear function is represented as:
[tex]C(x) = b + mx[/tex]
Where:
b represents the y-interceptm represents the slopeSo, we have:
[tex]C(x) = 250 + 5\% \times x[/tex]
Express 5% as decimal
[tex]C(x) = 250 + 0.05 \times x[/tex]
[tex]C(x) = 250 + 0.05x[/tex]
On a sale of $1500, the equation becomes
[tex]C(x) = 250 + 0.05 \times 1500[/tex]
[tex]C(x) = 325[/tex]
Hence. David would make $325 if he made $1500 in sales, and he would make 250 + 0.05x if he made $x in sales
