Rewrite the following equation in standard form. y=1/10x− 2/9

The answer is  9x - 90y = 20.

Explanation:

y = 1/10 x - 2/9

First eliminate the fractions by multiplying through by the LCM which is 90:-

90y = 9x - 20

Standard form is ax + by = c, so rearranging we get:

0 = 9x - 90y - 20

9x - 90y = 20 .

9x-90y=20

Step-by-step explanation:

Given equation is

y=1/10x-2/9

Ax+By=C where A,B and C are constants and x and y are variables.

We have to change given equation into standard equation.

y=1/10x-2/9

Adding -1/10x to both sides of above equation,we get

(-1/10x)+y=(-1/10x)+1/10x-2/9

-1/10x+y=-1/10x+1/10x-2/9

-1/10x+y=0-2/9

-1/10x+y=-2/9

Multiplying by 9 on both sides of equation,we get

9(-1/10x+y)=9(-2/9)

9(-1/10x)+9(y)=-2(9/9)

-9/10x+9y=-2

Multiplying by 10 on both sides of above equation,we get

10(-9/10x+9y)=10(-2)

10(-9/10x)+10(9y)=-20

-9x+90y=-20

Multiplying by -1 on both sides of equation,we get

-1(-9x+90y)=-1(-20)

-1(-9x)-1(90y)=20

9x-90y=20 is the standard form of equation where A= 9,B= -90 and C=20.

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'.
