I got you hun!
27= 3x is the equation you will need
27 is the total the coach needs making it the total. Since each pack comes with 3 you will mutiply the amount of pack, or x, by 3.
X=9
we know this because if you divide 3 by 27 to get it on the other side we get 9. This means the coach needs to buy 9 packs of baseballs for the team.
27=3(9)
Hope this helps!
Answer:
3.762 x 10^-7
Step-by-step explanation:
Alright this has the same exact concept as other scientific notation problems.
First, multiply your first numbers: 4.18 x 9 = 37.62
Next, we add our powers together -4 +-4 = -8 (can also be read as -4 - 4 = -8)
We now have 37.62 x 10^-8
Wait! This isn't in scientific notation.
Taking a closer look at this we see 37.62 x 10^-8 can be adjusted by moving the decimal over to the left. Scientific notation must be in simplest form with only one number on the left of the decimal. This gives up 3.762.
Now we need to adjust our notation. Since we moved the decimal over one we are adding one more power to our problem.
Our current power of -8 is now adding a power due to moving the decimal place over one unit to the left. This is equivalent to saying -8 + 1 which equals -7. Now that we fixed our powers, we can put our equation back together for our final answer
3.762 x 10^-7
Answer:
-20,2m-11,8
Step-by-step explanation:
rewrite it
2y+14,6m+3,8-(34,8m+15,6-2y)
remove the opposites
and then simplify
-20,2m-11,8
im not sure if this makes sense
It would be the last one because 5 columns are shaded and there are 10 columns all together. 50/100= 0.5
Hey there! :D
7(2x+6)=1
Use the distributive property. Multiply each number by each other.
7*2x= 14x 7*6= 42
14x+42=1
Subtract 42 on both sides.
14x= -41
Divide both sides by 14.
We know that 14 goes into -41 almost three times.
14*3= 42 (there is one left over)
-2 13/14 (we just need one more part of 14)
That is the simplified number.
I hope this helps!
