Answer:

1.) k + 516

2.) 2n - 4 = 3

3.) 57 - 2s

4.) 9h = 153

5.) c = 5n

Step-by-step explanation:

All of the problems given require you to set up an expression or equation.  Expressions have a variable and a coefficient or a constant.  Equations also have a variable, coefficient or constant but also include an equal sign.

1.) last year's miles = k, this year = 516, so total:  k + 516

2.) twice the difference of a number and 4 equals 3

twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3

2n - 4 = 3

3.) 57 decreased: 57 -; twice her savings: 2s:  57 - 2s

4.) 153 is:  153 =; the product of height and 9:  9h, so 9h = 153

5.) notebooks 'n', were $5 each:  5n; total cost = c, so 5n = c

39<br> 125°<br> Find the value of x
Savatey [412]

Answer:

Step-by-step explanation:

The sum of the interior angles of this triangle must be 180 degrees.

Thus, angle x is 180 degrees less (39 degrees plus 125 degrees), or

x = 180 degrees - 164 degrees = 16 degrees.

Because of the 125 degree angle, this is an obtuse triangle.

At a NASCAR racetrack, the distance per lap is 2 miles. Lou Lambert drives his car at a constant rate of 160 miles per hour. Ral
Nezavi [6.7K]

Answer:

<em>24 minutes</em>

<em></em>

Step-by-step explanation:

Given:

Distance per lap = 2 miles

Speed of Lou Lambert = 160 miles/hr

Speed of Ralph Redding = 170 miles/hr

Speed difference between the two = 170 - 160 = 10 miles/hr

Therefore, we can say that <em>Ralph gains 10 miles in 60 minutes </em>over Lou<em>.</em>

We have to find the time in which Ralph will gain 2 laps i.e. 2 \times 2 = 4 miles.

Let us use unitary method to find the required time.

10 miles are gained by Ralph in 60 minutes

1 mile will be gained in \frac{60}{10} = 6\ minutes

4 miles will be gained in 6 \times 4 = <em>24 minutes</em>
