Answer:
10.8
Step-by-step explanation:
Given that there are two numbers whose sum is equal to 27, you can set up an equation:
x + y = 27, where 'x' is the first number and 'y' is the second number
'The first number is 60% of the sum.' Set up another equation for the first number:
x = 27(0.6) or x = 16.2
Since x = 16.2, plug this number into the first equation and solve for 'y':
16.2 + y = 27
y = 10.8

Answer:
133.33g
Step-by-step explanation:
Let the:
Mass of 1.2g/cm³ of liquid = x
Mass of 1.8g/cm³ of liquid = y
From our Question above, our system of equations is given as:
x + y = 400........ Equation 1
x = 400 - y
1.2 × x + 1.8 × y = 1.6 × 400
1.2x + 1.8y = 640..... Equation 2
We substitute, 400 - y for x in Equation 2
1.2(400 - y) + 1.8y = 640
480 - 1.2y + 1.8y = 640
- 1.2y + 1.8y = 640 - 480
0.6y = 160
y = 160/0.6y
y = 266.67 g
Solving for x
x = 400 - y
x = 400 - 266.67g
x = 133.33g
Therefore, the mass of the liquid of density 1.2g/cm³ is 133.33g
4 feet and 2 inches would be the answer to that question
