PEMDAS- Parenthesis, Exponents, Multiply, Divide, Add, and Subtract.
First, do parenthesis.
(7+3)⁰
Add.
7+3=10
10⁰=1
= 1
Therefore, the final answer is 1.
The required expression evaluates to 1.
When we raise a number to the power of 0, the result is always 1, except when the base is 0 itself (as 0⁰ is undefined). This is a fundamental property of exponentiation.
In the given expression, (7 + 3)⁰, we have a simple addition inside parentheses. The sum of 7 and 3 is 10. Therefore, the expression simplifies to 10⁰.
Since any non-zero number raised to the power of 0 is 1, the value of 10^0 is equal to 1.
Hence, the expression evaluates to 1.

distribute 8 through the parentheses
16x - 112 + 13 = 4x - 27
combine like terms
16x - 99 = 4x -27
subtract 4x from each side
12x - 99 = -27
add 99 to each side
12x = 72
divide each side by 12
x = 6

32=16x2=2x2x2x2x2=2^5
48=24*2=6x4x2=2x3x2x2x2
Pick the highest number that occurs. In this case it is 2. Now we have to see how many times it appears in both. It appears 5 times in 32 and 4 times in 48. 4 is the highest number of times it appears in the numbers so:
2^4=2x2x2x2=16
The Greatest Common Factor (GCF) of 32 and 48 is 16.
The factors for 48 are −48,−24,−16,−12,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,12,16,24,48.
List of all the factors for 32 and 48.
32=−32,−16,−8,−4,−2,−1,1,2,4,8,16,32
48=−48,−24,−16,−12,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,12,16,24,48
The common factors for 32,48 are −16,−8,−4,−2,−1,1,2,4,8,16.−16,−8,−4,−2,−1,1,2,4,8,16
The GCF of numerical factors −16,−8,−4,−2,−1,1,2,4,8,16 is 16.

Answer:
Let A and B be the two rocks.
As per the statement: a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock
⇒Total weight of rock () =
pounds
or
Also, it is given A weighed a total of of the weight.
⇒
then;
Therefore, pounds did rock A weight.
Now
Total weight of the two rocks = 2 1/2 pounds
= 5/2 pounds
Then
Weight of Rock A = (5/2)/(1/7) pounds
= (5 * 7)/2 pounds
= 35/2 pounds
17 1/2 pounds
So Rock A weighs 17 1/2 pounds. This is the weight of Rock A and it is only required for this question. If you are eager to find the weight of rock B then you have to subtract the weight of Rock A form the total weight of the two rocks.

D.

Answers
x + y = 12
14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
14x + 10y = 140
-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = 12
5 + y = 12
y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
