Answer:

Jamie's claims are correct because 3/10 of the spool twine is left over after using 1/2 of the spool twin for friendship knot

Step-by-step explanation:

Full question: He claims to have 3/10 of the original spool of twine leftover.

First, we compare 3/10 with 4/5 - 1/2

The lowest common multiple for2 and 5 is 10.

To write 4/5 as a fraction with common denominator, multiply numerator and denominator by 2

4/5 = (4×2)/(5×2) = 8/10

To write 1/2 as a fraction with a common denominator, multiply denominator and numerator by5

1/2 =(1×5)/(2×5) = 5/0

So we have :

8/10 - 5/10

Since denominators are equal ,we go ahead and subtract

8/10 - 5/10 = (8-5)/10 = 3/10

You’re taking an exam in math, and you spend 5 minutes for every 2 questions you answer on the test.(Plz answer! I’m failing and
Natali5045456 [20]

Given:

Time spend on every 2 questions = 5 minutes.

To find:

The missing values for the given table.

Solution:

Let x be the number of questions and y be the number of minutes.

We have,

Time spend on every 2 questions = 5 minutes

Time spend on 1 question = \dfrac{5}{2}=2.5 minutes

Time spend on x questions = 2.5x minutes

Now,

y=2.5x

For x=0,

y=2.5(0)=0

For x=1,

y=2.5(1)=2.5

For x=2,

y=2.5(2)=5

For x=3,

y=2.5(3)=7.5

For x=4,

y=2.5(4)=10

Therefore, the required table is

Questions        :           0                1                2               3                 4

Time (minutes) :           0             2.5              5              7.5              10
