River C is 300 Miles Longer than River D. If the sum of their lengths is 5,570 miles, what is the length of each river?

d1i1m1o1n [39]

$x-\ length\ of\ river\ D\\
x+300-\ length\ of\ river\ C\\\\
5570=x+x+300\\
5570=2x+300\ \ \ | subtract\ 300\\5270=2x\ \ \ | divide\ by\ 2\\x=2635\\\\
River\ C\ is\ 2935miles\ long\ and\ river\ D\ 2635\ miles\ long.$

Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Step-by-step explanation:

we know that

The isosceles trapezoid has :

Two parallel sides not equal in length called its bases (KL and NM)

Two non-parallel sides equal in length (LM and NK)

$NK=\sqrt{5}\ units$

The perimeter is equal to

$P=KL+LM+NM+NK$

substitute the values

$P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}$

$P=(3\sqrt{2}+2\sqrt{5})\ units$

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

A clipboard costs $2.23. It costs $0.58 more than a notebook. Sheila bought two clipboards and one notebook. She paid with a ten

Troyanec [42]

Hey! So, you know she bought two clipboards. You're going to want to add 2.23 and 2.23 together, which is 4.46. Sheila only bought one notebook, so you simply add 4.46 and 0.58 together, which is 5.05. But, wait! She paid with a 10 dollar bill. Now, we have to take 5.05 out of 10.00, which is 4.95. Now, our answer is going to be $4.95 in change. I hope I helped! :)
