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

uysha [10]

Answer:

B

Step-by-step explanation:

eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.

The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.

Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .

PLEASE HELP-----The volume of the sandbox is 4575 cubic feet. If the length is 30.5 and the width is 10, what is the height?
Minchanka [31]

assuming you mean 30.5 and 10 feet, the height is 15 feet.

Step-by-step explanation:

Volume = length X width X height

so

4,575 = 30.5 X 10 X height

4,575 = 305 X height

4,575 / 305 = height

15 equals height
