Step-by-step explanation: if that doesn’t work sorry please don’t report I’m a student like, you
9. $112.50 / 9 lawns = $12.50 per lawn
10. $122.50 / 7 lawns = $17.50 per lawn
11. $112.50 / 7.5 hours = $15.00 per hour
$122.50 / 5 hours = $24.50 per hour
Alastair earns more per hour
12. Taryn: 49 more hours ($735 / $15.00)
Alastaie: 30 more hours ($735 / $24.50)
You found how much money they charge per hour in 11 so use that to find how many hours it takes to earn $735.
Answer:
x = -1 or x = -y
Step-by-step explanation:
Solve for x:
(x + 1) (x^2 + 2 x y + y^2) = 0
Split into two equations:
x + 1 = 0 or x^2 + 2 x y + y^2 = 0
Subtract 1 from both sides:
x = -1 or x^2 + 2 x y + y^2 = 0
Write the left hand side as a square:
x = -1 or (x + y)^2 = 0
Take the square root of both sides:
x = -1 or x + y = 0
Subtract y from both sides:
Answer: x = -1 or x = -y
Answer:
an = 6n -2
Or
an+1 = an +6
Step-by-step explanation:
to go from 4 to 10 we add 6 tiles
to go from 10 to 16 we add 6 tiles
We add 6 tiles each time
an = a1 + d(n-1) where an is the value of the nth term a1 is the first term d is the common factor and n is the term number
an = 4 + 6( n-1)
an = 4 + 6n -6
an = 6n -2
Or
an+1 = an +6
They are not equivalent because:
<em>6*3=18 </em>
but...
<em>4*3=12 <- </em>The ratio says "8" not "12"
If you don't get it just say and I'll explain it further. :)
Have an awesome day!
