White a number in the blank so that the equation will have an infinite number of solutions.

The equation 3x+5 = 3x- has infinitely many solutions.

-5

Step-by-step explanation:

The equation 3x+5 = 3x- has infinitely many solutions.

Simplifing these we will get

(-5)

Let's say the blank box is represented by y

3x+5 = 3x-y

3x-3x+5 = -y

5 = -y

Divide both sides by -1

5/-1 = -y/-1

-5 = y

-5

Step-by-step explanation:

3x + 5 = 3x - (-5)

3x + 5 = 3x + 5

Now both sides are identical which means every value of x will satisfy the equation. Hence infinite solutions

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
