Answer: The value of x is 3.

Step-by-step explanation:

so we know the surface area of the shape as 112.

And to find the missing angle  we could use the equation  

20 + 20 + (10 *x) + ( 10* x) +(2 * x) + (2 * x) =112   solve for x and that is x

20 + 20  + 10x + 10x + 2x + 2x = 112

40 + 24x = 112

-40              -40

 24x = 72

x= 3  

Check:  3 * 10 = 30

           3 * 10 = 30

           2 * 3 = 6

           2 * 3 = 6

            2 * 10 = 20

            2* 10 = 20

30 + 30 + 6 + 6 +20 +20 = 112

112 = 112

The vendor of a coffee cart mixes coffee beans that cost $9 per pound with coffee beans that cost $5 per pound. How many pounds
lidiya [134]

Answer:

56.25 pound of the coffee that costs $5 per pound is needed

18.75 pound of the coffee that costs $9 per pound is needed

Step-by-step explanation:

Let the number of pounds be x and y respectively

The total pounds is 75;

So;

x + y. = 75 •••••••(i)

Total cost of first type

9 * x = $9x

Total cost of second type;

5 * y= $5y

75 pound at $6 per pound; total cost of this is;

6 * 75 = $450

Thus;

9x + 5y = 450 ••••••••(ii)

From i, x = 75-y

Put this into ii

9(75-y) + 5y = 450

675 -9y + 5y = 450

4y = 675-450

4y = 225

y = 225/4

y = 56.25

x = 75 - y from i

x = 75-56.25

x = $18.75
