Answer:
Class 7A collected 4.8 ounces of pure gold.
Step-by-step explanation:
<u>Key skills required are: Percentages, Multiplication</u>
<u />
- We only need the information about Class 7A. They collected 40 oz that contains 12% gold.
- In other words, this means that 12% of that 40 oz gold sand is pure gold.
Here we have to do 12% x 40 to find the number of oz of pure gold. We first have to convert 12% into a decimal. Divide it by a 100 (or move the decimal point 2 places to the left) and you will get 0.12.
<em>Do 0.12 x 40 and you will get 4.8</em>
Therefore, there are 4.8 oz of pure gold in Class 7A's gold sand
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides
-6 (+10) = n/2 - 10 (+10)
10 - 6 = n/2
4 = n/2
Next, isolate the n. Multiply 2 to both sides
4(2) = n/2(2)
n = 4(2)
n = 8
8 is your answer

Answer:
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Since x-value increases by 3,
Δx = 3
And y-value decreases by 2,
Δy = -2
Therefore, slope = 
Slope = 
Equation of the line passing through (-2, 5) and slope =
will be,
y - 5 = 
y = 
y = 
y = 
Table for input-output values will be,
x -2 0 1 2 3
y 5 3.7 3 2.3 1.7
We can plot these points to get the line on a graph.
