Answer:
7:3
Step-by-step explanation:
The number of yellow marbles: the number of blue marbles
Answer:
CE= 9cm, DE= 5cm, CD= 10.2956cm
Step-by-step explanation:
Let E be the point of the other triangle.
Using Pythagoras' Theorem,
CD= square root symbol (CE^2 + DE^2)
= square root symbol (9^2+5^2)
= 10.2956cm (6 sf)
To subtract fractions, we need a common denominator.
-
the common denominator will be (y-2)(y+3)
The answer above will be the simplified form.
For 5a+5b+5c=-20
A= -4 - b - c
B= -4 - a - c
C= -4 - a - b
———————————
4a+3b+3c=-6
A= -3/2 - 3b/4 - 3c/4
B= -2 - 4a/3 - c
C= -2 - 4a/3 - b
———————————
-4a+3b+3c=9
A= -9/4 + 3b/4 + 3c/4
B= 3 + 4a/3 - c
C= 3 + 4a/3 - b
10,000 or 100,000 so I hope it helps
