The system of inequalities that can be used to determine he number of pencils that Mr.Carnegie can buy is 0.15x +0.75y < 30 and y < 3x.

<h3>What are inequality sign and what do they mean?</h3>

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

<h3>What are the system of inequalities?</h3>

The total amount spent on pens and pencils cannot exceed $30. Thus, the inequality sign to be used is <. Thus, the equation is: 0.15x +0.75y < 30 and 3x > y

kerry is comparing the number 9.207 and 9.210. what is the least place value she needs to compare to decide which number is grea
andrew11 [14]
The number 9.210 is greater. The least place value is the 0 (Zero) and the 1 (One). This is because the 9 (Nine) and the 2 (Two) in 9.207 and 9.210 is the same numbers. There so, you can't compare those 2 (Two) numbers.

How to solve which fraction is larger 10/13 or 11/14 or 14/15 or 17/18
alexandr402 [8]
To solve these type of problem you have to make the denominator the same or use the claculator.

let us do this problem by making the denominator the same.

\frac{10}{13} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{11}{14} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{14}{15}  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{17}{18} \\\\ \frac{10}{13}\times \frac{3780}{3780} \ \ \ \ \ \ \ \ \ \frac{11}{14} \times \frac{3510}{3510} \ \ \ \ \ \ \ \ \ \frac{14}{15} \times \frac{3276}{3276} \ \ \ \ \ \ \ \ \ \frac{17}{18} \times \frac{2730}{2730}

\frac{37800}{49140} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{38610}{49140}  \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{45864}{49140}  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{46410}{49140}

So, now. the one with the largest numerator is the largest fraction

In this case, \frac{46410}{49140} is the largest which is equal to \frac{17}{18}.

So, the largest fraction is \frac{17}{18}.

PLEASE HELP! I AM CONFUSED! Explain your answer, thank you so much! (I will give brainlyest)
antiseptic1488 [7]

Answer:

y+3 = 2(x-4)

Step-by-step explanation:

If we have a slope and a point, we can use the point slope form for an equation of a line

y -y1= m(x-x1)

where m is the slope and (x1,y1) is the point

y--3 = 2(x-4)

y+3 = 2(x-4)

A​ salesperson's ratio of successful signups to the number of people called is 0.625. This​ month, the salesperson had 125 signu
stellarik [79]

Answer:

The salesperson called 200 people this month.

Step-by-step explanation:

Let us denote the total people that the salesperson called by a variable "x".

Then,

The ratio of successful signups(success ratio) is given as=0.625

Then total no. of successful signups is the product of the success rate and the total no. of signups ,

i.e. Total successful signups = 0.625*x

According to the data given in the question,

The total no. of successful signups this month =125

or , 0.625*x= 125

or,  x=\frac{125}{0.625}

   ∴x= 200

So, the salesperson called 200 people, out of which only 125 signed up.

(Picture included)<br> Please solve:
DerKrebs [107]

Answer:

\$16.625\approx \$16.30

Step-by-step explanation:

Original price = $17.50

Discount = 5%

Find the amount of discount (in dollars):

5\%=0.05\\ \\\$17.50\cdot 0.05=\$0.875

Now, the sale price is

\text{Sale Price}=\text{Original Price}-\text{Discount}\\ \\\text{Sale Price}=\$17.50-\$0.875\\ \\\text{Sale Price}=\$16.625\approx \$16.30
