-9
Five more than twice a number is -13 find the number
zero (0) ; -5 - -5 = -5 + +5 = 0. Two things to note here:Any number subtracted from itself equals zero.Subtracting a negative number is the same as adding.
"Five Times the Difference" implies multiplying five by an operation of subtraction so you would represent it by using parentheses: 5(number - number). "Twice a number" means you are multiplying an unknown number, X, by 2. So you represent this as 2x. The equation now looks like: 5(2x - 14) "Is negative ten" basically means "Is Equal to -10." The final equation should look like: 5(2x - 14) = -10 Solve using distribution and combining like terms.
A Negative number but yes it is a number.
Yes. Write the number line horizontally with the negative numbers to the left, zero in the middle and positive numbers to the right, then the further right a number is, the greater it is; so with two numbers the number further right on the line is the greater of the two: Positive five is to the right of negative five, therefore it is greater than negative five, ie +5 > -5
As written, the question has no solution.It was supposed to read " ... negative number squared...", but was corruptedduring the complex typing operation. Had it been correctly typed, the answerwould have been -9 .
negative 5
No. -5 x -5 = -25 ... still a negative number.
54.3 squared
Five more than twice a number is -13 find the number
No because 25 is a rational number
We can't be sure from a reading of the question.The question could be saying " ... five times [ (a number X) squared ] ...",or it could be saying " ... (five times a number X) squared ...' .In the first case, it's [ 5x2 ] .In the second case, it's [ (5x)2 ] which is equal to [ 25 x2 ].

Five km2 = 1.93 square miles.
Five squared is 25
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
