Please help me write an equation for these two:
Ten fewer than the number of band instruments is 47 instruments.
The number of meters decreased by 25.6 is 84.3 meters
x-10 = 47
x-25.6 = 84.3
Sure! Let's write equations for each of the given statements.
1. Ten fewer than the number of band instruments is 47 instruments.
Let's represent the number of band instruments as 'x'.
The phrase "Ten fewer than the number of band instruments" can be written as 'x - 10'.
According to the statement, 'x - 10' is equal to 47.
So, the equation is:
x - 10 = 47
2. The number of meters decreased by 25.6 is 84.3 meters.
Let's represent the initial number of meters as 'y'.
The phrase "The number of meters decreased by 25.6" can be written as 'y - 25.6'.
According to the statement, 'y - 25.6' is equal to 84.3.
So, the equation is:
y - 25.6 = 84.3
These are the two equations representing the given statements.
To write an equation for these two situations, we need to use variables to represent the unknown quantities.
1. Ten fewer than the number of band instruments is 47 instruments.
Let's use the variable 'x' to represent the number of band instruments. The phrase "ten fewer than the number of band instruments" can be expressed as 'x - 10'. According to the given information, this expression is equal to 47 instruments.
So, the equation would be: x - 10 = 47
2. The number of meters decreased by 25.6 is 84.3 meters.
Let's use the variable 'y' to represent the initial number of meters. The phrase "the number of meters decreased by 25.6" can be expressed as 'y - 25.6'. According to the given information, this expression is equal to 84.3 meters.
So, the equation would be: y - 25.6 = 84.3
These equations represent the situations you described. Now, you can solve them to find the values of 'x' and 'y'.
