9x10 to the -8th power.
Since the numbers are both x10^-8, you can simply add 2 and 7. If you would rather look at it as:
0.00000007 + 0.00000002 = 0.00000009 = 10x10^-8
then you will get the same answer.
Answer:
31 + 21 = 52
Step-by-step explanation:
Calculation for the correct sum
First step is to factor 651 which means that 1 * 3 * 7 * 31 will give us 651
Second step is to find 3 possibilities numbers that will give us 10 as the difference
3 possibilities numbers =(31, 21), (93, 7), (217, 3)
Third step is to make use of equation 1 to find the numbers that has 10 as the difference among the 3 possibilities numbers
The number that has 10 as the difference is (31, 21) because 31-21 will gives us 10
Now Equation 1 = X – Y = 10
Where,
X=31
Y=21
Hence,
31 – 21 = 10
Since 31 – 21 gave us 10 as the difference which means that the correct sum will be:
Correct sum =31 + 21 = 52
Therefore the Correct sum is 31 + 21 = 52
Answer:
60
Step-by-step explanation:

The amount of shirts and pants the clothier makes is an illustration of a linear equation
The equation that represents the number of shirts, and the number of pants is 4s + 6p = 40
<h3>How to determine the equation</h3>
The rates are given as:
Shirts = 4 hours
Pants = 6 hours
In time t, the shirts and pants made is represented with:
t = 4s + 6p
Given that the time is 40 hours, the equation becomes
4s + 6p = 40
Hence, the equation that represents the number of shirts, and the number of pants is 4s + 6p = 40
