3/5 explanation because I’m big brain boii
5.7y-5.2=y/2.5
Add 5.2 to both sides:
5.7y = y/2.5 + 5.2
y/2.5 = 0.4y
5.7y = 0.4y + 5.2
Subtract 0.4y from both sides:
5.3y = 5.2
Divide both sides by 5.3:
y = 5.2/5.3
y = 0.98113
She drove 2 hours at 70 miles per hour, so she drove 70 * 2 = 140 miles total.
The jet traveled 400 miles per hour for 2 hours for a total of 400 * 2 = 800 miles.
Total miles = 140 + 800 = 940 miles.
The answer is C.
The answer is 11 because you do the smallest parenthesis. and work your way out.
Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
8
