Answer:
12y+9.48x=0
Step-by-step explanation:
Note dozen means 12 in mathematics
So 12 muffins cost $9.48
X muffins cost $y
So let's cross multiply
12×y=9.48×x
12y=9.48x
Substrate 9.48x from both sides
12y-9.48x=0
So the final equation is 12y-9.48x=0
A=3X-3
B=-X+3
If A+B=2X-2, then using equalivant exchange A=2X-2-B and
B=2X-2-A
If A-B=4X-8, then A=4X-8+B and -B=4X-8-A(or B=-4X+8+A)
Since A equals both 2x-2-B and 4X-8+B we can add both equations to equal 2A=6X-6 now we devide that by 2 to get
A=3X-3
Do the exact same for B, so b equals both 2X-2-A and -4X+8+A
We can add them both to get 2B=-2X+6 and decide that by 2 to get B=-X+3
Answer:
V = 200.96 m^3
Step-by-step explanation:
V=1/3hπr²
h=12, r=4
V = 1/3 (12) (3.14) (4^2)
V = 1/3 (12) (3.14) (16)
V = 200.96 m^3
Answer:
Step-by-step explanation:
The same way that you can perform any (most) operation(s) on both sides of an equation, you can do the same to the numerator and denominator of a fraction. Thus, simply multiply the numerator (4) and the denominator (10) to get 40/100 from 4/10. Then, because 40/100 and 8/100 have the same denominator, simply add the numerators 40 and 8 to get 48/100.
