2x-y=6 2x-y=6
x+y=36 2(36-y)-y=6
72-2y-y=6
x+y=36 72-3y=6
-y -y -72 -72
x=36-y <u>-3y=66</u>
x=36-22 -3y -3y
<em>x=14 y=22</em>
Answer:
Options b) and c) are correct
Step-by-step explanation:
Given: fractions are
To find: the common denominator
Solution:
Multiply both numerator and denominator of by 2
So, have same denominator 8.
Now multiply numerator and denominator of by 2,
Now multiply numerator and denominator of by 4,
So, have same denominator 16.
Hence, options b) and c) are correct
Answer:
8c²+66c+16
Step-by-step explanation:
By expanding paranthesis we get:
(c+8)(8c+2)=8c²+64c+2c+16=8c²+66c+16
Answer:
Sphere Volume = 4/3 * PI * radius^3
Sphere Volume = 4/3 * PI * 8^3
Sphere Volume = 4/3 * PI * 512
Sphere Volume = 2,144.7 cubic inches
