To find the percent of the question she got wrong, we have to divide 2 by 40, because she only missed 2.

\frac{2}{40}=\frac{1}{20}=0.05<h2>So, she got wrong 5% of the question only.</h2>

The expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

<h3>What is stated as the equivalent expression?</h3>
  • Equivalent expressions have been expressions that perform the same function despite their appearance.
  • If two linear algebra expressions are equivalent, they have the same value when the variable is set to the same value.

For the given question, the expression is stated as-

Negative 7 over 6 times t plus 4 over 9 end quantity minus expression quantity negative 5 over 12 times t plus 2 over 3 end quantity

This can be written as;

= -7t/6 + 4/9 - (-5t/ 12 + 2/3)

Simplify the expression as;

= -7t/6 + 4/9 + 5t/ 12 - 2/3

Re arrange the numbers

= -7t/6  + 5t/ 12 - 2/3 + 4/9

Combine the variables and constant separately.

= -9t/12 - 2/9

This can be written in words as- negative 9 over 12 times t minus 2 over 9.

Thus, the expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

Answer:

She can make cookies for 4.95 weeks

Step-by-step explanation:

2 x 1 2/3 = 3.333333333

16.5/ 3.333333333 = 4.95

Since Jordan is making two batches of Cookies per week, you need to multiply 2 by the amount of resources needed to bake one batch of cookies. So you multiply 1 and 2/3 by 2 to get the amount of resources neccesary for one week of making cookies. Then, you take the full amount of resources that she has, and divide that by the amount she uses per week, that number will give you the number needed to figure out how many weeks she has to bake cookies.

To figure out the number that is being divided to get the whole number in weeks, you would take the 16.5 cups of flour. The reason why this is, is because that Is the starting number of cups that she has. So here you would need to divide the amount you are taking from it each week. This will result in the amount of weeks that she is able to bake cookies with her flour.

One pipe fills a storage pool in 20 hours, another pipe fills the same pool in 15 hours.
erica [24]
X=time  of the third person it would take to fill the pool 
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20

Answer: the third person alone would fill the pool in 20 hours .
