SAT
1 answer:
frozen [14]3 years ago
8 0

Answer:

X=1

Explanation:

2x+3x=5x

Add the like terms

+5(5x-5)=(0)+5

Add 5 to both sides so you cancel 5

(5x)/5=(5)/5

Divide by 5 so that your x is alone

X=1

Patrick drives from p to q at an average speed of 40mph.
Bumek [7]

The distance in miles from P to Q is 12 miles

<h3>Distances and speed</h3>

Let the distance from P to Q be "d"

Since the formula for calculating speed is expressed as:

  • s =d/t

For the distance of P to Q

40 = d/t

d = 40t

If he drives back at an average speed of 45mph and 2 mintes less, then;

45 = d/t - 0.033

d = 45 (t - 0.033)

Equating both distances

40t = 45(t - 0.033)

40t = 45t - 1.485

-5t = -1.485
t = 0.297

Get the distance from P to Q:

d = 40(0.297)
d = 11.88 miles

Hence the distance in miles from P to Q is 12 miles

Why do you believe there has been an increasing interest in hemispheric specialization (the difference in right-brained and left
Fynjy0 [20]

Answer with Explanation:

"Hemispheric specialization" refers to an idea on how the different parts of the hemisphere (left and right) affects or controls the functions in the human body.

I believe there has been an increasing interest in hemispheric specialization because many people are <em>highly educated</em> nowadays which <em>makes them constantly curious with many things.</em>

Studying and investigating the roles of the two hemispheres allows people (the public) to know how their body's function. Exploring unknown areas of study is a normal activity for advanced species like the human beings.

Hemispheric specialization also allows health care professionals to know the underlying conditions of their patients and in this way, they can assist them with proper care.
