you are planting a rectangle garden. it is 5 feet longer than 3 times its width. the area of the garden is 250 feet. find the dimensions

Answers

Answer 1

Answer: l=3w+5
2(3w+5)+2w=250 (both w and l have to be multiplied by two because there are two sides)
This can be simplified to: 6w+10+2w=250
Now subtract 10 from both sides and add the two w's together.
This makes: 8w=260
Divide both by 8: 32.5-w=32.5
32.5 times 2=65
250-65=185, divided by 2=92.5

Length=92.5
Width=32.5

hope this helped!

David wants to pack 574 cereal bars into bags of 10 and bags of 8 the number of bags of 8 is 2 more than the bags of 10. How many bags of 10 and 8 can david pack the cereal bars into

Answers

Answer: Number of bags of 8. = 33

Number of bags of 10. = 31

Step-by-step explanation:

Let x = Number of bags of 8.

y = Number of bags of 10.

As per given.

$8x+10y= 574$ (i)

$x=y+2$ (ii)

Put value of x from (ii) in (i)

$8(y+2)+10y= 574\n\n\Rightarrow\ 8y+16+10y=574\n\n\Rightarrow\ 18y=574-16\n\n\Rightarrow\ 18y=558\n\n\Rightarrow\ y=(558)/(18)\n\n\Rightarrow\ y=18$

Put this in (i), x= 31+2=33

Hence,

Number of bags of 8. = 33

Number of bags of 10. = 31
