Answer: L=90-10t
0-90
1-80
2-70
3-60
Step-by-step explanation:
that should be right lol
because it decreases by ten a week so just count down by ten each week. Then, you can make the equation 90-10t and if you substitute each week for t it is true.
90-10(0)=90-0=90
90-10(1)=90-10=80
and so on...
Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y
Hope this helps ya! Keep smiling!
Answer:
N < 5
Step-by-step explanation:
"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50" can be written as $8 = ($1.50/ticket)*N.
Dividing both sides by ($1.50/ticket) results in
$8
---------------------- = 5 1/3 tickets
($1.50/ticket)
or N < 5.
