4.25
Step-by-step explanation:
To find the scale factor divide the image coordinates by the original coordinates, that is
scale factor = 
= 
= 4.25
Answer:
$8
Step-by-step explanation:
20% of 10 is 2 so 10-2=8
Answer:
Expression : 300,000 + 7x% = a
a = 384,000
Step-by-step explanation:
a = population in 4 years
x = every year increased
Expression: 300,000 + 7x% = a
300,000 + 7x% = a
replace x what will its population be in x years variable (this is 4)
300,000 + 7(4)% = a
multiply 7(4)
300,000 + 28% = a
Add 28% of 300,000 to 300,000
384,000 = a
<h3>
You need to add 4 to both sides</h3>
The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2
---------
Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10
I thin the answer is 625+250=875
So each student have to sell 35 tickets
35x25= 875
So I think the answer is 35
