Answer
<h3>Part a:</h3>
This part is already solved in the question:
<h3>Part b:</h3>
The graph is shown at the bottom
<h3>Part c:</h3>
The given equation is:
6 - 2x = 3
-2x = 3-6
-2x = -3
2x = 3
x = 3/2
x = 1.5
This can also be solve by seeing the graph. The equation which was given to us was y = 6 - 2x, and in this part we have to find the value of 3 = 6 -2x , which means y=3.
We can see in the graph that y = 4 when x = 1 and y = 2 when x = 2, so as y=3 is the midpoint of 4 and 2, the values corresponding to y = 3 should be midpoint of 1 and 2 i.e 1.5
Answer:
The copper percentage = 64%
Step-by-step explanation:
Given
- Nickle quantity = 9 grams of nickel
- Copper quantity = 16 grams of nickel
- Total quantity = 25 grams
The percentage of copper metal can be determined using the formula
Copper percentage = [Copper quantity / Total quantity] × 100
= [16 / 25] × 100
= 0.64 × 100
= 64%
Therefore, the copper percentage = 64%
To correctly apply the distributive property, we can multiply the parenthesized terms makong sure to have the correct positive and negative signs. Distributive the -2.1 by multiplying it by 3.4 to get -7.14 as your equivalent expression.
idk who the fu.ck cares just give me points XD
Answer:
7
3 times ? - 11
=
? + 3
? = 7
Step-by-step explanation:
3 times 7 is 21 -11 is 10
7+3 is 10
Both equations has to make 10 so it is the answer of 7
Hope this helps :)
