I believe that the answer is 10 because the first bottle will be exposed to the light 3 times and then the next will be exposed 4 times and then the next 5 and so on so by the tenth bottle it will have been exposed 12 times by the time she drinks it.
The answer is 10
Answer:
1.5y - 5
Step-by-step explanation:
I used the distributive approach and distributed -1/2 to the -3y and 10.
(If you try this and it's incorrect, you may just need to distribute -1/2 to the 10, creating -3y - 5.)
Answer:
a = -6/5
Step-by-step explanation:
For the graphs to be parallel the graphs should have same slope(m)
So we rewrite both our equations in the slope-intercept form then compare the slope to find the value of a like this,
This equation is the slope-intercept form we convert both our equations in this form firstly taking equation 1

so if we compare it with y = mx + b the coefficient of x is m and hence
m= -2/5 now solving for equation 2

so here if we compare it with y = mx + b the coeffienct of x is a/3 so since parallel lines have same slope by the formula:

we equation both the slope to each other to find the value of a like this,

so the value of a equals
a= -6/5
2x - 3 < 11 or 8x -10 < 82: <span>X < 23/2
<span>
Part 1</span>
</span>2x-3<11
Add 3 both sides
2x-3+3<11+3
Refine
2x<14
Divide by 2 on both sides
2x / 2 / 14 / 2
Refine
x < 7
<span>
Part 2</span>
8x-10<82
Add 10 to both sides
8x-10+10<82+10
Refine
8x<92
Divide by 8
8x / 8 / 92 / 8
Refine
x < 23 / 2
