The equation can be expressed as: ( 9 - 3x = 5(y + 5) ), where ( x ) is the unknown number being decreased and ( y ) is the unknown number being summed with five. This states that nine decreased by three times ( x ) is equal to five times the sum of ( y ) and five.
To write the equation based on the given statement, let the number be represented by ( x ). The phrase "20 decreased by two times a number" translates to ( 20 - 2x ), and "10 less than three times the number" translates to ( 3x - 10 ). Therefore, the equation is: [ 20 - 2x = 3x - 10. ]
Four times the unknown number. Let's say the unknown number is x. x + 3x = 4x
It is an equation in three unknown variables.
To solve the equation "three times a number equals the number minus 8," we can express it mathematically as (3x = x - 8), where (x) is the unknown number. Rearranging the equation gives us (3x - x = -8), which simplifies to (2x = -8). Dividing both sides by 2 results in (x = -4). Thus, the number is -4.
Let the number be represented as ( x ). The equation can be expressed as ( 30 - 3x = 3x - 6 ). By solving this equation, we add ( 3x ) to both sides to get ( 30 = 6x - 6 ), and then add 6 to both sides to obtain ( 36 = 6x ). Dividing by 6 gives ( x = 6 ).
let x=the number 87-3*(x)>165
The location of a point in 3-dimensional space.
Four times the unknown number. Let's say the unknown number is x. x + 3x = 4x
The number is 26
three times a number decreased by eleven
It is an equation in three unknown variables.
Answer = 7 - 3n
3x+32=4x-15 3x-4x=-15-32 x=-47
x + x - 3 = 2x - 3
(x3 - 1)/(x - 1) = x2 + x + 1
.6n - 1 = 23 .6n = 24 n = 40
How do you write half a number decreased by 8 is equal to the sum of the number and 14
