Answer:

x = 10

y = 25

Step-by-step explanation:

if you add the equations as they are then the 'y-term' is eliminated:

60x = 600

x = 10

substitute x=10 to find value of 'y':

40(10) + 4y = 500

400 + 4y = 500

4y = 100

y = 25

Check:

20(10) - 4(25) should equal 100

200 - 100 = 100

100 = 100

The largest side of a triangle is six more units than the smallest side. The third side is twice the smallest side. If the perim

svetlana [45]

Equation: x + x + 6 = 2x = 25
smallest side is 4.75 units
largest size is 4.75 + 6 = 10.75 units
3rd side is 2(4.75)= 9.5 units

smallest side is x
largest size is x + 6
3rd side is 2x
-----------------------------------
4x + 6 = 25
-6 -6
4x = 19
 4 4

x = 4.75 is the smallest side

smallest side is 4.75 units
largest size is 4.75 + 6 = 10.75 units
3rd side is 2(4.75)= 9.5 units

pochemuha

ok so divide 1500 by 250 to determine how many boxes you need to by in 1 year

so that equals 6 then you multiply that by $30 to find the total cost of all the diapers per year so the is $180 per year and then multiply that by 3 to find the cost of all 3 years

So the answer is you will spend $540 in total
