Answer:
63
Step-by-step explanation:
I'm pretty sure its 63
- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So firstly, add both sides by 9x:
Next, divide both sides by 10 and <u>your slope-intercept form is </u>
Now looking at our slope-intercept form equation, <u>the slope is 9/10 and the y-intercept is (0, -9/10).</u>
Answer:
10
Step-by-step explanation:
Here it's given that the area of the shaded region is 48 u² and we need to find out the value of x .
The given figure is made up of two rectangles where the smaller one is inscribed into the bigger one .
- The area of shaded region will be equal to the difference of the areas of the two rectangles , that is equal to 48 u² .
- The area of rectangle is length × breadth .
- The dimensions of bigger rectangle is (x+3)(x-4) and that of smaller one is 3 × x .
So that ,
ar(bigger) - ar(smaller) = 48
[ (x+3) (x-4)] - 3(x) = 48
[ x² - 4x +3x -12 - 3x ] = 48
x² -4x -12 -48 = 0
x² - 4x - 60 = 0
x² - 10x + 4x - 60 = 0
x( x -10) +4(x -10) = 0
(x +4)(x-10) = 0
x = -4,10
- Since sides can't be negative ,
x = 10

Hence the required answer is 10.</h3>
Answer: 10 nickels
Step-by-step explanation:
A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:
= 12 * 0.01
= $0.12
The amount she has in nickels at most is therefore:
= 0.66 - 0.12
= $0.54
A nickel is $0.05 so the number of nickels are:
= 0.54/0.05
= 10.8 nickels
= 10 nickels
If she has 10 nickels then the total she would have is:
= (12 * 0.01) + (10 * 0.05)
= $0.62
