Solve by trial and error method :

a) 5 x - 3 = - 8.​

x = -1

Step-by-step explanation:

5x - 3 = -8

Trial and error means make a guess and then see if it is right and if not make another guess

Let x =0

5*0 -3 = -8

-3 = -8

We need a number that is negative for x

Let x = -1

5(-1) -3 = -8

-5-3 = -8

-8 = -8

x = -1

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
