A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $26. Option B is a commission rate of 10% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?
Step-by-step explanation:
12,500.
Step-by-step explanation:
We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.
First of all we will find amount earned by salesperson with option A.
\text{Option A earnings}=40\times 25=1000Option A earnings=40×25=1000
The salespersons earns $1000 through option A.
Let x be the amount of weekly sales.
8% of x should be equal to 1000 for salesman to earn the same amount with the two options.
\frac{8}{100}x=1000
100
8
x=1000
0.08 x=10000.08x=1000
x=\frac{1000}{0.08}x=
0.08
1000
x=12500x=12500
Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.

Answer:
ANGLE 1 = 40°
Step-by-step explanation:
angle 1 = angle 2 ------(alternate interior angles)
2x + 20 = 3x + 10
20 - 10 = 3x - 2x
x = 10.
Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.

add like terms
30 + 7k = 100
100-30 = 70
70 divided by 7k = 10
k = 10
4. add the z's together
2z - 6 -2 = -10
+ 6 + 2
-10 will be -2 now since we dragged the -6 and -2 to the other side
2z = -2
z = -1
5. 3.2x - 1.7x = 1.5x
1.5x + 5.5 = 10
10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5
3.2x = 5.5
x = 1.71875

Here is a system of equations:
-7x + 3y = -65
-7x + 10y = -135
Write an equation that results from subtracting the two equations.
Answer:
y = -10
Step-by-step explanation:
(-7x+3y) - (-7x +10y) =-65 -(-135)
-7x + 3y + 7x -10y = 70
-7y = 70
y = -10
The equation that results from subtracting - 7x + 3y = - 65 and
- 7x + 10y = - 135 is 7y = - 70.
What are simultaneous equations?We know two simultaneous equations have a unique solution when they intersect at a point,
when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.
Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.
Subtracting the first equation from the second we get,
- 7x + 10y = - 135
(-) - 7x + 3y = - 65
_________________
Negative sign gets distributed
- 7x + 10y = - 135
+ 7x - 3y = + 65
_________________
7y = - 70
y = - 70/7
y = - 10.
So, the value of x is -7x +10×(-10) = - 135.
- 7x - 100 = - 135.
- 7x = - 135 + 100.
- 7x = - 35.
x = 7.

A 12% brine solution was mixed with a 16% brine solution to produce a 15% brine solution. How much of the 12% solution and how much of the 16% solution were used to produce 40 L of the 15% solution?
Answer:
10 liters
Step-by-step explanation:
x=12% solution, y=16% solution
x+y=40
0.12x+0.16y=6 . (12x+16x=600)
-12x-12y=-480
12x+16x=600
+ -12x-12y=-480
-------------------------------
4x=120
x=30
12% solution= 30 liters
16% solution= 10 liters
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Let 12% brine solution be x.
Let 16% brine solutions be y.
12% brine solution was mixed with a 16% brine solution to produce 40L of the 15% solution.
This can be written as,
x + y = 40 ______(1)
0.12x + 0.16y = 0.15 x 40
0.12x + 0.16y = 6 _______(2)
We will solve for x and y.
From (1) we get,
x + y = 40
x = 40 - y _____(3)
Putting ( 3) in (2)
0.12 (40 - y) + 0.16y = 6
4.8 - 0.12y + 0.16y = 6
4.8 + 0.04y = 6
0.04y = 6 - 4.8
0.04y = 1.2
y = 1.2/0.04
y = 30
Putting in (3) we get,
x = 40 - 30 = 10
Thus,
10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.

m(n+r)=s solve for n. Show two methods.
9514 1404 393
Answer:
n = (s/m) -r n = (s -mr)/mStep-by-step explanation:
1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.
m(n+r) = s . . . given
n +r = s/m . . . divide by m
n = (s/m) -r . . . subtract r
__
2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.
m(n+r) = s
mn +mr = s . . . eliminate parentheses
mn = s -mr . . . subtract the added term
n = (s -mr)/m . . . divide by the coefficient of n
