Answer:
2 hours
Remember that time = distance/rate
The distance you need to cover is 56 miles, while you go 28 miles per hour. Using these, we get this:
time=56/28
time=2
So it will take two hours to go across a 56 mile wide bay at 28 mph.
Step-by-step explanation:
(x+2)(x+3)
=x^2 +2x+3x+6
=x^2 + 5x + 6
answer: x^2 + 5x + 6(third choice)
Answer: Square root (52), No
Step-by-step explanation:
Answer:
121°
Step-by-step explanation:
The angle with measure x is an exterior angle of the triangle.
The angles measuring 90° and 31° are the remote interior angles to the exterior angle.
<em>Theorem:</em>
<em>In a triangle, the measure of an exterior angle equals the sum of the measures of its remote interior angles.</em>
x = 31 + 90
x = 121°
Answer:
The value of x is 322/5 OR 64.4 in decimal form.
Step-by-step explanation:
To find the value of x, start by following the order of operations for solving equations. The step-by-step is below for you.
5/7x + 17 = 63 ----> Subtract 17 from both sides.
5/7x = 46 -----> Multiply both sides by 7/5.
x = 322/5 OR 64.4
