Answer:68-c=M

35

Step-by-step explanation:m is the number needed, it is the thing we are trying to find, so lets start out by putting it as the thing we need to equal

=m

Now, what equals m?

However many blocks Tegan still needs to make. What do we know? We know she needs 68 in all, and she has already made some. If we take away c, which is how many she has made, then we will have the number she still needs.

68-c

=m

68-c=m

Convert to scientific notation ​
andreev551 [17]

Answer:

8.245*10^6

Step-by-step explanation:

scientific notation is known as c*10^n

c : any number from 1-10

n : the power of base 10

the number in our case between 1 and 10 is 8.245

but then we want to move the decimal 6 spaces to the right, so we multiply that by 10^6
