Solve the equations. 2.5x−3.67=1.52
aleksklad [387]
Our current equation is:
2.5x -3.67 = 1.52.
To solve for x, we need to get x by itself and then simplify what we can from there.
2.5x -3.67 = 1.52
Add 3.67 to both sides to get 2.5x by itself.
2.5x = 5.19 is now our new equation.
Divide both sides by 2.5 to get x.
5.19/2.5 = 2.07
x = 2.07
I hope this helps!

I need help with this problem bk I’m so konfused by it

Do you want 5 and 6 or just 5? 5 is kind of neat.

44.5% = 0.445

4/9 = 0.4444444

You have enough information to put the numbers in order.

0.44 is the smallest number.

0.44444444.... is the next smallest number

0.4445 is bigger than the number above. 5 is in the ten thousandths place. that is bigger than 4 in the thousands place of 4/9

Finally the largest number of all is 0.445 for the same reason given above.

Six

5/12 = 0.416666

0.4

42% = 42/100 = 0.42

0.416

0.4 is the smallest number

0.416 is the next smallest number

0.41666666 is bigger than 0.416 because you are adding a bunch of 6s onto the decimal place.

The largest one is 0.42. You can put these into your calculator to verify the results. For example, 0.42 - 0.4166666 = 0.003344. Any result more than 0 will show that the first number is bigger than the second.

There are 5 red marbles and 12 silver marbles in a bag. You randomly choose one of the marbles. What is the probability of choos
AleksandrR [38]
So we know there are 5 red and 12 silver marbles, together making 16 marbles.

This would mean that there is a 5/17 chance of choosing a red marble.

When you do the math to convert 5/17 into a decimal, it turns into being a .29 chance.

Convert .29 into a decimal, and you know that you have a 29% chance of grabbing a red marble.

Hope this helped!
