Suppose you are driving to visit a friend in another state. you are driving 55 miles per hour. you must drive 440 miles total. i
Oliga [24]
Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours

Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours

Answer: 3 hours

Find all numbers whose absolute value is – 3.
Gwar [14]

Answer:

remember that |x|=x if x\geq0 and |x|=-x \; \text{ if } x\leq 0. This means that |x| always is a positive number.

Then, there are no numbers such that |x|=-3 because -3 is a negative number.

Need the help thanks guys
Diano4ka-milaya [45]

Answer:

x=−5+√29 or x=−5−√29

Step

Let's solve your equation step-by-step.

x2+10x+10=14

Step 1: Subtract 14 from both sides.

x2+10x+10−14=14−14

x2+10x−4=0

For this equation: a=1, b=10, c=-4

1x2+10x+−4=0

Step 2: Use quadratic formula with a=1, b=10, c=-4.

x=

−b±√b2−4ac

2a

x=

−(10)±√(10)2−4(1)(−4)

2(1)

x=

−10±√116

2

x=−5+√29 or x=−5−√29
