Which equation is equivalent to 2x+3y=12

Answers

some possible equations equivalent to 2x+3y=12 would be:

1)

y=−2x+12/3

written form:

y= negative 2x plus 12 over/divided by 3

2)

y=−2/3x+4

written form:

y= negative 2 over/divided by 3x plus 4

3)

y=4−2/3x

written form:

y= 4 minus 2 over/divided by 3x

4)

y=12−2x/3

written form:

y= 12 minus 2x over/divided by 3

those are all i could think of! Hope this helped :)

The equivalent expression for the equation 2x + 3y = 12 are:

x = 6 - 3y/2

y = 4 - 2x/3

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

2x + 3y = 12

We need to find an equivalent expression for this equation.

We can have many forms:

Case 1.

2x + 3y = 12

Subtracting 3y on both sides.

2x + 3y - 3y = 12 - 3y

2x = 12 - 3y

Dividing 2 into both sides.

x = 12/2 - 3y/2

x = 6 - 3y/2

Case 2.

2x + 3y = 12

Subtracting 2x on both sides.

2x + 3y - 2x = 12 - 2x

3y = 12 - 2x

Dividing 3 into both sides.

y = 12/3 - 2x/3

y = 4 - 2x/3

Thus the equivalent expression for the equation 2x + 3y = 12 are:

x = 6 - 3y/2

y = 4 - 2x/3

Answers

Answer:
$1.21

Explanation:
What we know:
- $5.88=3 pounds of apples
- price went up by $0.75 per pound

First, we divide $5.88 by 3 to find out how much one pound of apples cost.

5.88/3
=1.96

Therefore, the new price of apples per pound is $1.96.

Because the old price of apples per pound was $0.75 cheaper, we subtract 0.75 from 1.96.

1.96-0.75
=1.21

Therefore, the old price of apples per pound was $1.21.

Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?

Answers

Answer: 20.25

Step-by-step explanation: Rebecca can expect to be making her regular 13.50 an hour, however once time and a half hits she’s looking at taking her 13.50 and dividing it by 2. So 13.50 divided by two is 6.75. You then take that 6.75 and add it on top of her regular 13.50 hourly. Putting you at 20.25 for time and a half.

Twice the sum of three and a number is 30. Find the number

Answers

9514 1404 393

Answer:

2(x +3) = 3012

Step-by-step explanation:

When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:

  2(x +3) = 30 . . . . an equation for the given conditions

__

We can solve this equation by dividing by 2:

  x + 3 = 15

  x = 12 . . . . . . subtract 3

The number is 12.

angles a and b are vertical angles. If mA = (5x – 24)° and m B = (3x + 24),
then find the value of x.

Answers

Answer:

The correct answer is x = 24.

Step-by-step explanation:

To solve this problem, we must remember that vertical angles have the same measure.  This lets us set up the following equation:

m<a = m<b

If we substitute their values, we get the following:

5x - 24 = 3x + 24

To solve this equation, we can first subtract 3x from both sides of the equation.

2x - 24 = 24

Next, we can add 24 to both sides of the equation.

2x = 48

Finally, we can divide both sides of the equation by 2.

x = 24

Therefore, the answer is x = 24.

Find the value of MN if AB = 9 cm, BC = 7.2 cm, and LM = 12 cm.
ABCD - LMNO

Answers

Answer:

9.6 cm

Step-by-step explanation:

Since the shapes are similar, we can write a proportion. Let x be the length of MN.

9/12 = 7.2/x Write a proportion.

9x = 12(7.2) Use cross products.

9x = 86.4 Multiply.

x = 9.6 Divide both sides by 9.

Side MN is 9.6 cm.

This story originally appeared in Chatterbox, a book of stories edited by J. Erskine Clarke.Which line from the story supports the idea that Fred is a courageous boy?It was Saturday afternoon when the boys of Wedderburn School went off as usual to swim their boats on a beautiful lake. Fred Langton had a new boat, which his grandfather had sent to him as a birthday present. It was a larger and better-constructed boat than any of the others. Each boy was, of course, eager that his own boat should win the race. Although all the boys admired Fred's boat and wished that they could have had one as good, they felt no grudge towards Fred himself. In fact, he was a general favorite in the school. He was kind-hearted, unselfish, and always willing to give anything that he had to his companions.I tell you, said Bill Cowan to his own particular chum, Joe Morris, that boat of Fred's will beat ours all hollow! I wish I had one as good!Well, suppose it does win, replied Joe Morris, I shall not grudge it to him, for Fred is no sneak; he is out-and-out the jolliest fellow in Wedderburn School.So he is, said Bill Cowan, and no mistake about it. Well, here we are at the lake, and now for some fun.On this particular Saturday, however, Fred was going to become famous in quite another way. The little boats were all in full sail, and the schoolboys were shouting with glee at the fun. Suddenly a fox-terrier took it into his head to chase the boats and show that he could swim as well as they could. Poor dog! It was quite true that he could swim. Unfortunately he got caught among weeds. He began struggling in the water and barking for help.Oh, I say, I can't stand this! cried Fred Langton; he will be drowned. I must go in and fetch him out!No, no! cried Bill Cowan; the lake is quite deep just at that place.Yes, I know it's deep, added Joe Morris, and, besides, you can't swim, Fred; don't be silly. Who cares for a dog being drowned?I do, for one, cried Fred, and dashing into the water he waded out to where the poor dog was half-standing, half-lying, among the choking weeds. Yes, the water was deep; but stretching out his arms he contrived to catch hold of the poor animal, and he quickly waded back to shore amid ringing cheers from all the people who had now gathered on the bank to watch the plucky lad. And whose was the dog? Nobody knew; it seemed, indeed, to have no owner and no home. But Fred and his companions carried it back with them to the school, and, after having told their tale, they begged the head master to keep it for himself. As Dr. Williams could not discover anything about the dog's ownership, he did keep it. So Fred's brave deed not only saved the animal's life, but procured a good home for it as well. what of the following are functions of lipids? choose three correct answers derive ideal gas equation for n mole of gas.
