Answer:
$1.6
Step-by-step explanation:
The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost
Using the concept of cross multiplication we say that if
1.45 is equivalent to $2.32
1 is equivalent to x
Therefore, the company incurs $1.6 for each plug
Answer:
y = 2x - 7
Step-by-step explanation:
To find the line equation we assume that its form is y = m*x + b. Where m is the slope and b is the independent variable that intercepts the Y axis.
If we have two points as P1=(x1,y1) and P2=(x2,y2) we can use the slope formula as:
m = (y2-y1)/(x2-x1)
The points given are P1=(7,7) and P2=(2,-3), then the using the slope formula we obtain:
m = (-3-7)/(2-7)
m = (-10)/(-5)
m = 2
By now the equation is y = 2x + b. To find the value of b we have to replace in the equation any point, in this case i am using P2:
-3 = 2*(2) + b
-3 = 4 + b
-3 -4 = b
-7 = b
Therefore the equation of the line is:
y = 2x - 7
Srry I don’t know this but I’m sure You’ll find d answer
Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10−2x=19x+2−5x
10+−2x=19x+2+−5x
−2x+10=(19x+−5x)+(2)(Combine Like Terms)
−2x+10=14x+2
−2x+10=14x+2
Step 2: Subtract 14x from both sides.
−2x+10−14x=14x+2−14x
−16x+10=2
Step 3: Subtract 10 from both sides.
−16x+10−10=2−10
−16x=−8
Step 4: Divide both sides by -16.
−16x/−16 = −8/−16
x = 1/2
