The answer is $2.50 because you do 145-132.50=12.5
Then you divide by 5 because that’s the difference between students then the final answer is 2.50
Yes and for a. You can just put y=x [y=1x is bascually the same but just the 1 isnt needed]
Answer:
x=2
x=-5
Step-by-step explanation:
You need to get everything on one side to have a quadratic equation:
x^2+6x-4 -(3x+6) = x^2+3x-10
All factors of 10 are 1*10 and 2*5.
5-2 = 3 and 5*-2 = -10
Factoring x^2+3x-10 gives us (x-2)(x+5)
x=2
x=-5
Apologies if it’s dark but here’s the work for your question. If you need an explanation, let me know.
The shipping fee is $30
1. 12%×250
= 250×12/100
= 2.5 ×12
= 5/2×12
=60/2
=30
