Answer: 3
Step-by-step explanation:
12+3 =15
8*60 minutes = 480
4*60 minutes = 240
480-240=240
240 miles
Answer: -x
step-by-step explanation:
convert the mixed numbers to improper fractions 125/6 = 77/6
77/6x-14x+1/6x
77/6x-14x+1/6x = -1 times x
= 1 times x
multiply 1 times x = x
= x
Answer:
The answer is the last line.
Step-by-step explanation:
Use the quadratic formula
a = 1
b = -a
c = a^2 - b
x = -b +/- sqrt(b^2 - 4ac)
=================
2a
x = a +/- sqrt(a^2 - 4(1)*(a^2 - b)
========================
2
x = a +/- sqrt(a^2 - 4a^ + 4b)
=====================
2
x = a +/- sqrt(4b - 3a^2)
===================
2
