Answer:
y = 
and x = 
Step-by-step explanation:
To solve simultaneous equations, you need to have the number in front of both x's or y's the same. (signs doesn't matter)
To get -x to -10x we simply need to multiply the first equation by 10:
-x * 10 = -10x
-9y * 10 = -90y
16 * 10 = 160
-10x - 90y = 160
Now we can add the two equations:
-10x + 10x = 0
-90y + 20y = -70y
160 + 20 = 180
-70y = 180
70y = -180
7y = -18
y =
Now plug into the second equation:
10x + 20() = 20
10x - 
= 20
Move the over to the other side, making it a positive:
10x = 20 +
10x = 
Divide both sides by 10:
x =
So y = and x =

__Data__
The equilateral's lengths are all the same
Also if AB = AD = BD = CD that would mean all those sides have the exact same length
Answers and Explanations
15A. BCD has 2 acute angles and one obtuse angle, so this is an Obtuse Triangle
15B. If beforementioned = 5 cm
Then the perimeter is 5cm x 3 = 15cm
15C. ABC is a Right Triangle
16. abcdef. Measure the angles using a protractor
17. The shortest side of ABC is AB which is 5cm, the longest is AC which is 10cm
Shortest side: Longest side
5cm:10cm
1:2 is the ratio
Answer:
Given:
Radius of large sphere: R1
Volume of sphere: V1
Radius of small sphere: R2
Volume of sphere: V2
R1=2R2
We know that:
Volume of a sphere: 4/3πR^3
Volume of large sphere: 4/3πR1^3
Now we know that R1=2R2(given)
Thus volume of large sphere(V1) 32/3πR2^3.
Volume of small sphere(V2): 4/3πR2^3.
Ratio of volume of large sphere to small sphere is 8:1.
