When you add the degrees of all the angles in a triangle you should get 180
A= 5x+5
B= 90
C= 3x+5
5x + 3x = 8x
5 + 90 + 5 = 100
8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8
x = 10
Now plug 10 into angles A and C
5(10)+5= 55
3(10)+5= 35
A= 55 , B= 90 , C=35
.0018529956763434 is my calculated answer.<span />
There will always be 34.5L of water in the cups because no water is removed.
Therefore the cups still total 34.5L after the water is poured from one to the other.
The smaller cup has some amount of water we'll call x.
The larger cup has nine times this, so 9x.
We know that x + 9x = 34.5.
We can simplify this to 10x = 34.5.
Divide each side by 10...x = 3.45.
So, we know that the smaller cup had 3.45L of water at the end.
Since 0.68L was poured in, it must've started with 2.77L. (3.45 minus 0.68)
We can also conclude that the larger pail had 31.73L .
(35 minus 2.77, or 9 times 3.45 plus 0.68)
Answer:
15 necklaces 5 bracelets
Step-by-step explanation:
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
