5. You are making your Halloween costume this year. You have 6 yards of fabric and the pattern says that you need to cut it in t

REY [17]

Answer:

The shorter side piece of fabric = x = 8 feet

The longer side piece of fabrics = (x + 2) = 10 feet

Step-by-step explanation:

Total yards of fabrics = 6 yards

you need to cut it in two pieces where one is two feet longer than the other.

First piece= x feet

Second piece= x+2 feet

Convert 6 yards to feet

6 yards = 18 feet

First piece + second piece = total piece of fabrics

x + (x+2) = 18

x + x + 2 = 18

2x + 2 = 18

2x = 18 - 2

2x = 16

Divide both sides by 2

x = 16 / 2

x = 8 feet

8 feet = 2.66667 yards

x + 2

= 8 + 2

= 10 feet

10 feet = 3.33333 yards

The shorter side piece of fabric = x = 8 feet

The longer side piece of fabrics = (x + 2) = 10 feet

Nick's Printing Press promptly sold 5-cent pencils and 10-cent pens to the public. It sold 1000 writing utensils and took $74.50

galben [10]

Answer:

490 pens
510 pencils

Step-by-step explanation:

Let p represent the number of pens Nick sold. Then the revenue is ...

0.10p +0.05(1000 -p) = 74.50

0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50

p = 490 . . . . . . . . . . . . multiply by 20

The number of pencils sold is then ...

pencils = 1000 -490 = 510

Nick's Printing Press sold 490 pens and 510 pencils.
