Answer:
The value of the expression is 0.5.
Step-by-step explanation:
To evaluate, we need to do order of operations.
To solve, we start with the parenthesis because they come first in the order of operations.
-1+3[(10-12)³/(-16)]
-1+3[-2³/-16]
Now we do the second thing in the order of operations, which is to simplify the exponents.
-1+3[-8/-16]
Now we do the third thing left to do, which is to do division and multiplication from left to right.
-1+3[0.5]
-1+1.5
Now we do the last thing left to do, which is to do addition and subtraction from left to right.
0.5
So the value of this expression is 0.5.

n = 4 and p = 6? MP 2

D 3.6
O E 6
Answers
Answer:
2
Step-by-step explanation:
mn + p = m + 3n, n = 4 and p = 6
m(4)+6=m+3(4)
4m+6=m+12
4m=m+6
3m=6
m=2
Answer:
B) 2
Step-by-step explanation:
Step 1: Plug in the values of n and p.
[tex]m(4) + 6 = m + 3(4)[/tex] [tex]4m + 6 = m + 12[/tex]Step 2: Subtract m from both sides.
[tex]4m + 6 - m = m + 12 - m[/tex] [tex]3m+6=12[/tex]Step 3: Subtract 6 from both sides.
[tex]3m + 6 - 6 = 12 - 6[/tex] [tex]3m = 6[/tex]Step 4: Divide both sides by 3.
[tex]\frac{3m}{3} = \frac{6}{3}[/tex] [tex]m = 2[/tex]Step 5: Check if solution is correct.
[tex](2)(4)+(6)=(2)+3(4)[/tex] [tex]8 + 6 = 2 + 12[/tex] [tex]14 = 14[/tex]Therefore, the answer is B) 2.

Answer:
The first box is 4, the second box which is above the third box is 12 and the third box is 8
Step-by-step explanation:
To add fractions, you have to find like terms. So, you have to make 1/2 have a denominator of 8.
8/2 is 4, so 1/2 equals 4/8.
Now, the first box above the 8 will be 4.
The second and third boxes will be the sum to 4/8+8/8 which is 12/8.

Answer:
a) x = (√5 -1)/2 ≈ 0.618034
b) 1/x = (√5 +1)/2 ≈ 1.618034
Step-by-step explanation:
Given:
x/(1 -x) = 1/x
Find:
Exactly, and as a decimal approximation, ...
a) x, using the quadratic formula
b) 1/x
Solution:
a) We can multiply the given equation by x(1 -x) to obtain ...
x² = 1 -x
x² +x -1 = 0 . . . . . . add x-1
The coefficients for use in the quadratic formula are a=1, b=1, c=-1. The solution using the quadratic formula is ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-1\pm\sqrt{1^2-4\cdot1\cdot(-1)}}{2\cdot1}=\dfrac{-1\pm\sqrt{5}}{2}[/tex]
We are only interested in the positive solution, which is ...
[tex]\boxed{x=\dfrac{\sqrt{5}-1}{2}\approx0.618034}[/tex]
__
b) The quadratic we developed in the first part can be rearranged like this:
x² +x = 1 . . . . . . add 1 to both sides
x(x +1) = 1 . . . . . factor out x
x +1 = 1/x . . . . . .divide by x
Then to find the value of 1/x, we simply need to add 1 to the value of x we have:
[tex]\dfrac{1}{x}=\dfrac{\sqrt{5}-1}{2}+1=\dfrac{\sqrt{5}-1}{2}+\dfrac{2}{2}=\dfrac{\sqrt{5}-1+2}{2}\\\\\boxed{\dfrac{1}{x}=\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

jeff makes the generalization that a 10s fact can be broken into two 5s facts. write an equation to test his generalization
Answers
Expressions can be simplified by breaking it down into several sub expressions.
The equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]
The original expression is:
[tex]\mathbf{Expression = 10s}[/tex]
Express 10s as 5s + 5s
[tex]\mathbf{10s= 5s + 5s}[/tex]
Apply distributive property
[tex]\mathbf{10s= 5s(1 + 1)}[/tex]
Add 1 + 1
[tex]\mathbf{10s= 5s \times 2}[/tex]
Rewrite as:
[tex]\mathbf{10s= 2 \times 5s }[/tex]
Hence, the equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]
