Create an equation modeling the scenario. Use the equation to solve for the missing number. In your final answer, include the equation and all necessary calculations. Twice the sum of a number and seven is three times the number.

Answers

Answer 1

Answer:

2(n+7)=3n

Step-by-step explanation:

"A number" is unknown so just create a variable in this case I made it "n."

We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.

Answer 2

2 (n+7)=3n Hopefully this helps !!!

5-4t = 6

Answers

The answer is negative one fourth.

t = 1/4

-----

First, rearrange the subtraction problem

5 - 4t = 6 is the same as -4t + 5 = 6

-----

Next, subtract 5 from both sides

-4t + 5 - 5 = 6 -5

This is known as the Subtraction property of equality.

-----

Then, since 5-5 is 0 and 6-5 is 1

-4t = 1

-----

Then, you would divide that so

-4/-4 = 1/-4

-----

So your answer would be

1/4!

In the mid-19th century, the quest for control of the West led to the annexation of Texas and the Mexican–American War. ... This expansion led to debates about the fate of slavery in the West, increasing tensions between the North and South that ultimately led to the collapse of American democracy and a brutal civil war.

In Science class, Mrs. Olson had 30.6 pounds of metamorphic rock. Mrs. Olson had to divide the rocks into 9 different containers for a class assignment. If the rocks are equally divided into 9 different containers, how many pounds of rock will be in each container?

Answers

The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.

the answer is most likely 3.4

Kathryn is cooking pancakes. The recipe calls for 3 2/9 cups of flour. She accidentally put in 5 4/5 cups. how many extra cups did she put in?

Answers

subtract
29/5 - 29/9
261/45 - 145/45
116/45

Answer

So basically you need to subtract 5 4/5 - 3 2/9

then you do all this:

= (5-3) + (4/5 - 2/9)

= 2+ 4x9/5x9 - 2x5/9x5

= 2 + 36/45 - 10/45

= 2 + 26/45

= 2 26/45

So then the answer is 2 26/45
