Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right
Hi! Welcome to Brainly! Let's solve this word problem together below! :)
Let's write this as a system of equations.
8a+4s=880
a= s+20
Let's plug our a value into the first equation.
8(s+20)+4s=880
8s+160+4s=880
We combine like terms.
12s+160=880
We subtract 160 from both sides.
12s=720
We divide both sides by 12
s=60
Now, we plug this value into the second equation.
a= 60+20
a= 80
Therefore, 80 adult tickets were sold.
I hope this helps! Have a fabulous time here at Brainly! :)
the answer is 3:20 to 6:00 which equals 3 hours and 20 minutes
Infinitely many solutions means that you have the same thing on both sides of the equation no matter what value of x you plug in, right?
We just need both sides to be 3x then, correct?
If a were equal to 3 and b were equal to 0, we'd have
3x = (3)x + 0
Which is essentially 3x = 3x
So that means a = 3 and b = 0 must work!
Let's say x = 5
3(5) = 3(5) + 0
15 = 15 + 0
15 = 15
That means that a = 3 and b = 0 is your final answer :)
