Plz do the equation and tell the answer too ?

ANSWER:

Constant - 55

Variable - x

Equation - y=55x

EXPLANATION :

We have to form an equation to fit the standard form of y= mx+ b

If the car is going 55 miles per hr, we can fill this in for what would be m.

y = 55x + b.

Seeing that we aren't making a graph, we assume that b is non existent, or is the number 0. This means we can remove it from the equation.

y = 55x

We now have to decide what to use for the variable. For algebraic purposes, we will stick to x for the explanation.

y= 55x

Hope that helped

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
