<h3>Answer:  40 inches</h3>

==========================================================

Explanation:

  • x = first piece
  • 2x = second piece, since its twice as long as the first
  • 5x = third piece, since its five time as long as the first

x is some positive real number, and the units of each are in inches.

Add up the smaller pieces and we should get 64 inches back again

x+2x+5x = 64

8x = 64

x = 64/8

x = 8

The first piece is 8 inches long.

2x = 2*8 = 16 is the length of the second piece (in inches)

The third piece is 40 inches because 5x = 5*8 = 40

--------

Summary:

first = 8 inches

second = 16 inches

third = 40 inches

Check: 8+16+40 = 64, which confirms the answer

Pam spelled 68 of 100 words correctly on the pretest. How many words did she miss? If she learns 8 of those each day, how long w
Fofino [41]

Answer:

Pam missed 32 words in her pretest.

It will take 4 days for Pam to learn all missed words.

Step-by-step explanation:

Given:

Number of words spelled correctly = 68

Total number of words on the pretest = 100

We need to find the number of words she missed.

Solution:

now we can say that;

Number of words she missed can be calculated by subtracting Number of words spelled correctly from Total number of words on the pretest.

framing in equation form we get;

Number of words she missed = 100 -68 =32\ words

Hence Pam missed 32 words in her pretest.

Now Given:

Number of words missed learned each day = 8

Total number of words missed = 32 words.

We need to find how long will take to learn them all.

now we can say that;

days required to learn missed words is equal to total number of words missed divided by Number of words missed learned each day.

framing in equation form we get;

Days required to learn missed words = \frac{32}{8}=4\ days

Hence It will take 4 days for Pam to learn all missed words.

vaieri [72.5K]

Answer:

x=67 y=113 x=52

Step-by-step explanation:

85+28= 113

180-113=67

67= x

67+28=95

95+85=180

y= 28+ 85 =113

113+15= 128

180-128=52

52=x
