Answer:
3.5×10^4=35000
Step-by-step explanation:
Consider the value
3.5
we are saying that we are counting in units (1's) in that we have
3

Consider the value

. Now we are saying we have

of tens. That is; 3 lots of 10 is 30 and
1
2
of 10 is 5 so we have
30

Consider the value

So if we are counting in 100's then the decimal point stays where
it is and we move the number of 3.5 to the left until the
3 becomes hundreds.
Note that we have to insert a place holder of 0 just to the left of the decimal point to make sure the three is viewed as in the hundreds.

Answer:
0.51km × 1000 = 510m
510m × (3×7) = 510m × 21 = 10710m in whole
Step-by-step explanation:
first we transform km to m (multiply by 1000)
then we count how much days are in three weeks ( 3 weeks × 7 days)
then we just multiply the meters per day × the days
99% it's true
Subtract 3 from both sides
simplify 12 - 3 to 9
break down the problem into these two equations
1 + p = 9 and -(1 + p) = 9
solve the first equation 1 + p = 9 and that would be 8 since 1 + 8 = 9 is true.
solve the second equation -(1 + p) = 9 and just simplify brackets and add 1 to both sides then add 9 + 1 and lastly multiply both sides by -1 and p = -10.
Gather both solutions
Answers: p = -10, 8
Answer:
the coefficient in the equation is 13
Step-by-step explanation:
a coefficient is a number that is in front of a variable. 13 is in front of the variable u so it is the coefficient.
