The average of two numbers is 55. If their positive difference is 64 determine the numbers algebricly

Y= 87 - 64 = 23

Step-by-step explanation:

Let one number be x and the other y

(x + y)/2 = 55

x-y = 64

x + y = 110

x - y =    64

adding the last 2 equations; 2x = 174; giving x = 87

substituting x = 87 into the second equation gives y = 87 - 64 = 23\

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
