Answer:
-23
Step-by-step explanation: You have to combine like terms first:
-3.8x -5.9x =223.1
-9.7x = 223.1
Then divide om each side of the equation by -9.7.
-9.7x/-9.7 = 223.1/-9.7
x =- 23
Answer:
The volume of the cube is;
Step-by-step explanation:
The parameters of the prism are;
The number of cubes used to fill the prism, n = 70 cubes
The side length of each cube, s = 1/2 unit
The volume of the cube, V = n × s³
∴ Therefore, the volume of the cube, V = 70 × (1/2)³ =
= 8.75 cube unit
Answer:
Both proportions are equivalent.
Step-by-step explanation:
We have been given two proportions
and
. We are asked to find why the solutions to our given proportions are equal.
We can solve proportions by cross multiplying them.
After cross multiplying our both proportions we will get same equation that is:




Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.
