Answer:

in explanation

Step-by-step explanation:

angle rules say that those angles respond to each other meaning

they will equal each other

so 6x-4=4x+14

now solve for x

x=9

the top angle will be

6(9)-4=50

bottom angle will be 50

4(9)+14=50

The longest side of a triangle is 8 more units than the shortest side. The third side is 4 times the length of the shortest side

Answer:

10 3/4, 4 3/4, and 9 1/2

Step-by-step explanation:

We're going to let x represent the length of the longest side. The perimeter is

x +(x-6) +2(x-6) = 25

4x -18 = 25

4x = 43

x = 43/4 = 10 3/4

Then x-6 = 4 3/4.

Multiply that two to get 8 3/2 = 9 1/2

I hope this helped! :)

Robert and Chris can skate 4 miles in 18 minutes. How far can they ride in 45 minutes?

Answer: Robert and Chris can skate 10 miles in 45 minutes.

Step-by-step explanation:

Let's start by finding the unit rate.

$\frac{4}{18} =\frac{2}{9} \\\frac{18}{18} =1$

Robert and Chris can skate $\frac{2}{9}$ of a mile in 1 minute. Now we can multiply both by 45 to see how far the can go in 45 minutes.

$(\frac{2}{9}) (\frac{45}{1} )\\\frac{(2)(45)}{(9)(1)} \\\frac{90}{9} \\10$

45x1=45

The can skate 10 miles in 45 minutes.
