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

if i dont eat for a week how much weight will i gain?
Answer:
Your body can maintain itself for a week or two without access to food and water and possibly even longer if you consume water. Those who experience starvation will need to be monitored by a doctor to get back to health following the time period without nourishment to avoid referring syndrome.
Step-by-step explanation:
its not safe dont think about it dude
Answer:
Around 5 pounds
Step-by-step explanation:
While some may think that not eating will make them lose weight, it doesn't. When your body doesn't get the nutrients it needs, it senses danger, and holds on to body fat to help you stay strong.

Given f(x) = -x + 6 write an equation for f(x + 3).
Answer:
-fx +9f
(i think)
Step-by-step explanation:
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
k/6 + 8 = 5 what does k=?
Answer:
The answer is k= -18
Step-by-step explanation:
hope this helps
k/6 + 8 = 5
1/6k+8-8=5-8
1/6k=-3
To find I divide both sides by 1/6.
1/6k/1/6=-3/1/6
k= -18
The value of k in the equation k/6 + 8 = 5 is -18.
The given equation is k/6 + 8 = 5 .
We have to find the value of k.
Let us isolate the term with variable k by subtracting 8 from both sides:
k/6+8-8=5-8
k/6=-3
Apply cross multiplication:
k=-18
Hence, the value of k is -18.
