Somebody pls help I’m doin a exam

x=2

y= -3

Step-by-step explanation:

3x+2y=0    2y=-3x, y=-3x/2

3x-15y=51

substitute y

3x-15(-3x/2)=51

3x+45x/2=51

multiply by 2

6x+45x=102

51x=102

x=2

y= -3

x=2

y=-3

Step-by-step explanation:

Ok so

Since this problem is practically set up all you have to do is solve it! So what i did was try to cancel both of the x's so that I am just left with the y. I subtract everything and end up with

17y = -51

Now, all you have to do is divide giving you the answer for y which is

y = -3

Next, you have to plug in the value of y to either the first equation or second equation in the question. I chose the first equation and once I plugged it in it looked like this.

3x - 6 = 0

Now, add 6 to both sides giving you

3x = 6

Now all you have to do is divide

x = 2

TAADAA!!!

If you want to check your answer if you're unsure just plug in both values to either the first equation or second equation in the original problem. Okay well have a good day!! :D

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'.
