Let's help Tyler simplify the expression correctly.

6-2x+5+4x

Add the x's:-

-2x+4x

Now add the numbers:-

6+5

Put the terms together (but don't add them, since 11 and 2x are not like terms)

11+2x

An equivalent expression would be

2x+11 (switch the order)

Answer:

Tyler grouped up 6-2 and 5-4 instead of grouping up the x terms.

6-2x + 5+4x=

2x+4x= ?

6 + 5 = 11

11- 2x + 4x =

-2x + 4x = 2x

2x + 11

I need it ASAP! Tristan swam around a lake 8 times. The distance around the lake was 0.25 miles. He swam at an average of 60 min

yarga [219]

Total of 8 times
Distance is 0.25 miles

8 * 0.25 is 2 so a total distance of 2 miles

We know his avg swim rate to be 60 minutes per mile, meaning if he traveled 2 miles then we multiply it by 60 to get our total time taken.

60min/mile * 2 miles = 120 minutes total

So, step D is the same as what I've done to calculate the total time it will take Tristan to swim around the lake.

Can someone help me find x

Viefleur [7K]

Answer:

Rounded to the nearest tenth: $x=5.7$ in

Rounded to the nearest hundredth: $x=5.74$ in

Step-by-step explanation:

We have a right triangle with a given angle of 35°. We also have the opposite side of that angle, $x$ , and its hypotenuse 10 in. To find $x$ , we are using the trig function that relates the opposite side with the hypotenuse; in other words, the sine trig function.
