B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.
Answer:
The answer would be 7.5 degrees colder or -7.5
Step-by-step explanation:
5x+12 5/7=72 5/7
subtract 12 5/7 from each side
5x +12 5/7 - 12 5/7=72 5/7- 12 5/7
5x = 60
divide by 5 on each side
x = 60/5
x=12

The volume of a square pyramid is:
First, calculate the volume of pyramid A
Next, the volume of pyramid B
To calculate how much more sand the greater pyramid has, we simply calculate the absolute difference (d) between their volumes
Answer:
Step-by-step explanation:
We can find the derivative using the <u>chain rule.</u>
To get the derivative of an expression with an exponent you multiply the expression by the exponent and raise it to the power of the exponent minus one.
Then multiply it by the derivative of the expression inside the parentheses.
The derivative of 4x+3 is 4, so multiply the rest by 4.
Therefore the derivative is:
