1)
x= -2y
2. (-2y)+4y=0
0=0
2)
x+2x= -3
x=-1
y= -2
3)
7x+2x+2=4
9x=2
x=2/9
y=2/9+1
y=11/9
Answer: There are 28.375 grams in an ounce.
Step-by-step explanation:
Given: Total grams in a pound =454 grams
Total ounces in a pound = 16 ounces
Therefore, 16 ounces = 454 grams
To find grams in an ounce, we need to divide 454 grams by 16, we get
The total grams in an ounce=
∴The total grams in an ounce= 28.375 grams
Hence, there are 28.375 grams in an ounce.
Answer:
Option A. 14.13 cu. in
The volume of the water balloon is 14.13 in³
Step-by-step explanation:
First we calculate the radius
r = 3in / 2
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 1.5in
π = 3.14
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * 3.14 * (1.5in)³
V = 4.187 * 3.375 in³
V = 14.13 in³
The volume of the water balloon is 14.13 in³
