Step-by-step explanation:
to make it perpendicular 2/3 becomes -2/3
Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h
Part 1:
3+2+1 = 6 total units
There is only 1 history book.
1/6 total.
Part 2:
6-1 (we've lost the history book) = 5 total units
3 novels. = 3/5
Part 3:
1/6 * 3/5 = 3/30 or 1/10
<em>x</em> = liters of 1% solution
<em>y</em> = liters of 5% solution
<em />
<em>x</em> + <em>y</em> = 16
0.01<em>x</em> + 0.05<em>y</em> = 0.04*16 = 0.64
<em />
<em>y</em> = 16 - <em>x</em>
<em />
0.01<em>x</em> + 0.05(16 - <em>x</em>) = 0.64
0.01<em>x</em> + 0.8 - 0.05<em>x</em> = 0.64
0.16 = 0.04<em>x</em>
<em>x</em> = 4
<em>y</em> = 12
