Answer:
x = 14/3
y = 16.3333333333
Step-by-step explanation:
Step 1. equal them to each other and solve for x
2x + 7 = 5x - 7
5x - 2x = -14
3x = 14
x = 14/3
Step 2. Plug in the value of x and solve for y
y = 5x - 7
y = 16.3333333333

Answer:
8 + f i know this is right because i had the same question
Step-by-step explanation:
The approximate mass of the spherical weight is 51 pounds
To answer the question, we need to know what the mass of the sphere is
<h3>Mass of the sphere</h3>
The mass of the sphere m = ρV where
- ρ = density of steel = 0.284 lb/in³ and
- V = volume of sphere = 4πr³/3 where
- r = radius of sphere = 3.5 in
So, m = ρV
= ρ4πr³/3
Substituting the values of the variables into the equation, we have
m = ρ4πr³/3
= 0.284 lb/in³ × 4π(3.5 in)³/3
= 0.284 lb/in³ × 4π × 42.875 in³/3
= 48.706π lb/3
= 153.014 lb/3
= 51 lb
The approximate mass of the spherical weight is 51 pounds
