Help me understand please ;-;Which shows the equation in standard form?

6y - 12 = -3x

Which shows the equation in standard form?

10 - 2(x - y) = 3x + 1

Answers

standard form for first one is
ax+by=c

6y-12=-3x
add 3x both sides
3x+6y-12=0
add 12
3x+6y=12

second one
distribute (don't forget double negative y)
10-2x+2y=3x+1
minus 3x both sides
10-5x+2y=1
minus 10 both sides
-5x+2y=-9

the equations are
3x+6y=12
-5x+2y=-9

The standad form of linear equation is of the form Ax + By = C, where A, B and C are integers.
Here, the standard form of the eduation 6y - 12 = -3x is 3x + 6y = 12

Least to greatest7/12 2/3 5/36 2/7

put them in order from least to greatest it might help if u put them in decimals

Answers

5/36 2/7 7/12 and 2/3

5/36 = 0.139
2/7 = 0.285
7/12 = 0.583
2/3 = 0.667

so the order is 5/36 , 2/7 , 7/12 , 2/3

Sofia is correct because if you replace x with 7 you multiply 3 and 7 and get 21 then add 4 and your final answer will be 25

If a>b and b>c, what is true about the relationship between a and c? Explain your reasoning

Answers

You could say that A is the biggest of the three letters and C is the smallest of the three letters. This is shown because A is bigger than B, but B is bigger than C, which means C is less than A and B, and A is greater than B and C.

Please help!Sarai uses 4 cm3 of face wash each night. The cylindrical container of face wash is 10 cm tall and has a diameter of 5 cm. The container is half empty.How many more days will the face wash last her? Use 3.14 to approximate pi, and round your answer to the nearest whole number.

A.196 days

B. 98 days

C. 49 days

D. 25 days

Answers

first you need to find how much is left in the container by finding the whole volume.
cylinder volume= πr²h where r is the radius and h is hight
V= (3.14)*(5²)*(10)
V=(31.4)(25)
V=785cm³ is the total volume
now half has been used so divide that number in half
785/2= 392.5cm³
now she uses 4cm³ a day so divide
392.5/4= 98.125
round to the nearest whole number
answer is B 98

Well I took the test and used the 98 days answer but it was wrong its actually 25 days
