Answer:

x=7

Step-by-step explanation:

The angles will always add up to 180.

Subtract 76 from 180, giving you 104

So now, your other two angles when added together equals 104.

104=5x+6+8x+7

Add your like terms, so add 5x and 8x to give you 13x, and add 6 and 7 to give you 13. Subtract 13 from both sides, leaving you with 91=13x

Divide 13 from both sides, giving you 7=x

Now plug in the 7 for the x for the original expressions. So 5x+6= 5×7+6

5×7=35+6=41

8x+7=8×7+7

8×7=56+7

56+7=63

A train leaves Roseville heading east at 6:00 am at 40 miles per hour. Another eastbound train leaves on a parallel track at 7:0
Molodets [167]

Answer:

At 11:00 am the both trains will be at same distance away from Roseville

Step-by-step explanation:

The first train was 40 miles away from Roseville at 7:00 am

After some time t the both trains will be at the same distance away from Roseville.

We will make equation for that situation

d- distance      v1= 40mph and v2= 50mph -  velocity

d =  v1*t + 40 = v2*t  => v2*t - v1*t = 40 => t (v2-v1) = 40 -> t = 40/ (v2-v1)

t = 40/(50-40) = 40/10= 4h      t = 4h

7:00 am * 4h = 11:00 am

Good luck!!!

Which mixed number is equivalent to the improper function below? 46/10
Valentin [98]

Answer:

B. 4 and 6/10

Step-by-step explanation:

in order to find this answer i've always had a trick where i first off find an even number to divide these with and in this case that would be 4 and then the leftovers would be 6/10 and in this case your answer would be right there 4 and 6/10 but if needed to be simplified it would be 4 and 3/5

hope this helps, if it did please make sure to like and rate and give me the brainliest if possible!

have a good day!
