Answer:

i think its x=16 or x=11

Step-by-step explanation:

∠2 = 90 - 42 = 48 degrees

3x degrees = 48 degrees

3x = 48

x = 16

If f(x) = −3x + 4 and g(x) = 2, solve for the value of x for which f(x) = g(x) is true.Noah started to solve the equation –4.6p

barxatty [35]

Answer:

p = 1.2

Step-by-step explanation:

The given equation is :

–4.6p – 6.3p + 3.9 = –9.18

Combining the like terms,

–4.6p – 6.3p = -9.18 - 3.9

−10.9p = −13.08

⇒ $p=\dfrac{-13.08}{-10.9}\\\\p=1.2$

Hence, the value of p is 1.2

Zaria is going down to the arcade to play

Nana76 [90]

Answer:

I believe that it would be y=$0,25x+$5

Step-by-step explanation:

The initial cost to get into the arcade is $5 so that would be the y-intercept (b) in a slope equation (y=mx+b). Since each game costs $0,25, then that would be the slope (m) and x would be the number of games she played. y would equal the total amount of money spent. So if she played 10 games, substitute 10 for x and multiply by 0,25 and take the answer and add 5 to get the total amount.

2 hours after a freight train leaves delhi a passenger train leaves the same station traveling in the same direction at an avera

insens350 [35]

The average speed of the freight train was 10.67 km/hr.

<h3>What is average speed?</h3>

The average speed is the total distance traveled by the object in a particular time interval.

Now it is given that,

Average speed of the passenger train = 16 km/hr

Time taken by passenger train to overtake the freight train = 4 hours

So, the distance between two trains = Average speed of the passenger train * Time taken by passenger train overtake the freight train

⇒ distance between two trains = 16 * 4 = 64 km

Thus, Distance to be covered by freight train = 64 km

Since, freight train leaves the same station in the same direction after 2 hours.

Hence, total time taken to cover 64 km by freight train = 2 + 4

= 6 hours

⇒ Average speed of the freight train = Distance covered by freight train/total time taken to cover 64 km

⇒ Average speed of the freight train = 64/6 km/hr

⇒ Average speed of the freight train = 32/3 km/hr

or, Average speed of the freight train = 10.67 km/hr

Thus, the average speed of the freight train was 10.67 km/hr.

1. set up the equation which makes these shapes equal, 1/2(2(x+1)) = 1x

2. solve, x+1=x, 1=0

3. since this is impossible, there is no solution and zero answers
