Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?
Answer:
6 days
Step-by-step explanation:
pay 60 = -60
Let d = the number of days
30d - 60 = sister
20d = me
Equation:
30d - 60 = 20d Move 30 to the other side
-30d -30d
-60 = 20d - 30d Combine liked terms
-60 = -10d
-10 -10 Divide
d = 6

Find the equation of the line thatis perpendicular to y =
contains the point (4,-8).
- 2/3 x
Answer:
y= 3/2x -14
Step-by-step explanation:
The formula to solve this problem is y- y1 = m(x-x1), so plug in the coordinates according to the formula: y-(-8)= m(x-4). Then, find the reciprocal of the slope, which is 3/2. Plug 3/2 to where the slope belongs: y+8=3/2(x-4). Calculate to solve the rest: y =3/2x -14

Evaluate 36 = (x +9) when x=3.
A.4
B.21
C.12
D.3
Answer:
C
Step-by-step explanation:
The value of the equation 36 = (x +9) when x=3 is 12. option C is correct.
To evaluate the expression 36 = (x + 9) when x = 3.
we substitute the value of x into the expression:
36 = (3 + 9)
We know that the value of three plus nine is twelve.
Now, we simplify the expression inside the parentheses:
36 = 12
Hence, the value of the equation is 12.

Help please! Thanks, answer only if you know how to do this.
Answer:
2 radians
Step-by-step explanation:
The ratio of the arc length to the circumference is the same as the measure of angle AOB in radians to 2pi. 2pi radians is a full circle. We can now construct an equation, with x being our answer.
[tex]\frac{6}{6\pi } =\frac{x}{2\pi } \\\frac{1}{\pi } =\frac{x}{2\pi }\\1=\frac{x}{2} \\2=x[/tex]
First, we try to simplify both sides. Next, we multiply both sides by pi. Then, we multiply both sides by 2. Finally, our answer is 2, so 2 radians.

To raise money for homecoming the student council sold a total of 240 tickets to a basketball game the number of adult tickets sold was 2 times the number of student tickets based on this information would it be reasonable for the student council to have sold 160 student tickets and 80 adult tickets
Answer:
no
Step-by-step explanation:
because the number of student tickets 160 is higher than the number of adult tickets 80 and the information tells us that the adult tickets were twice the amount of student tickets sold. If the numbers were swapped to be adult=160 and student=80 then it would be correct.
