Sally grew 18 flowers with 9 seed packets. How many seed packets does Sally need to have a
total of 44 flowers in her garden? Assume the relationship is directly proportional.
Answer:
22 seed packets
Step-by-step explanation:
we can look at this in a couple of ways. the first way to solve this is an algebraic problem. we know that 18 flowers came from 9 packets so 18 is going to be on one side of the equation while 9 is going to be on the other. we dont know how many seeds were in each packet though so we will use x to represent the amount of seeds. now our equation looks like this: 18 = 9x. heres how to solve it:
given: 18 = 9x
to get x alone we divide each side by 9 because its the opposite of muliplication: 2 = x
answer: x = 2 seeds per packet
another way we could figure this out is by using proportions. when we see the ratio flowers to packet is 18:9, we can tell that it needs to be simplified. we know both 9 and 18 are divisible by 9 so when we do that we get the answer, our ratio of flowers to packets is 2:1.
next, we need to look back at how we solved that problem we just did, and plug in our new numbers. when doing it algebraically, we follow these steps:
plug in: 44 = (x)2
x times 2 is equal to 2x: 44 = 2x
to get x alone divide each side by 2 because its the opposite of multiplication: 22 = x
answer: x = 22
if we want to solve it using ratios and proportionalities, we set it up flowers to packets like before so we have the ratio 44:x. seeing that the ratio was 2:1 last time, we know that 44 is 2 times x, or x is 1/2 (half) of 44. so we can find half of 44 to get x. half of 44 is 22 so 44:22 is the ratio's answer.

Rewrite this single inequality as two inequalities with AND connector. -6 < x < 12 x > -6 and x < 12 x > 12 and x > -6 x < -6 and x > 12
Answer:
The single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Step-by-step explanation:
For the single inequality -6 < x < 12,
To write the single inequality as two inequalities, first we will separate it into two as
-6 < x and x < 12
-6 is less than x means x is greater than -6, Hence, -6 < x can be written as
x > -6.
∴-6 < x and x < 12 becomes
x > -6 and x < 12
Hence, the single inequality -6 < x < 12, can be written as two inequalities thus
x > -6 and x < 12
Therefore, the correct option is the first one
x > -6 and x < 12

tammy will order both macaroni and potato salad. She estimates that she will spend a total of $38 on 7 pounds of salad. She uses this system of equations to show how many pounds of macaroni salad, m, and potato salad, p, she plans to buy. 5m + 6p = 38 m + p = 7 How many pounds of each salad does Tammy plan to buy?
Answer: Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds
Step-by-step explanation:
From the question,
5m + 6p = 38 ......... i
m + p = 7 .......... ii
Multiply equation i by 1
Multiply equation ii by 5
5m + 6p = 38 ....... iii
5m + 5p = 35 ....... iv
Subtract equation iv from iii
p = 3
Since m+p = 7
Therefore, m + 3 = 7
m = 7-3
m = 4
Marcaroni salad = 4 pounds
Potatoes salad = 3 pounds

Let |AB| = The length of the rectangle.
|BC| = The Width of the rectangle.
Hence Area = |AB| × |BC|

A certain county has a population of 34,237 people. The county hospital is interested in estimating the number of people in the county with blood-type A−. To do this, they test blood samples from 245 patients. Out of this group, 12 have blood-type A−. Use this sample to estimate the number of people in the county with blood-type A−.
Answer:
About 1677 people in the county will have blood-type A−.
Step-by-step explanation:
From the question, 12 out of 245 patients have blood-type A−.
To estimate the number of people in the county which has a population of 34,237 people with blood-type A−, we will assume that for every 245 people out of the 34,237 people, 12 of them have blood-type A−.
Let the number of people with blood-type A− in the county be x.
Now,
If 12 people out of 245 people have blood-type A−
Then, x people out of 34237 people will have blood-type A−
245 × x = 34237 × 12
245x = 410844
x = 410844/245
x = 1676.9
x ≅ 1677
Hence, about 1677 people in the county will have blood-type A−.

Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) to be 3. Which best describes his error? Ankur multiplied the compatible numbers 15 and –3. Ankur found that the quotient of a positive number and a negative number is negative. Ankur found that the quotient of a positive number and a negative number is positive. Ankur added the compatible numbers 15 and –3.
Answer:
Ankur found that the quotient of a positive number and a negative number is negative
Step-by-step explanation:
Given that:
Quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
Mathematically,
( 15 1/3) ÷ (-4 2/3) = 3
Here,
Dividend = 15 1/3 (positive)
Divisor = - 4 2/3 (negative)
Dividing a positive Dividend by a negative Divisor will always give a negative quotient
Hence,
15 1/3 = 46 / 3
-4 2/3 = - 14 / 3
46/3 ÷ - 14/3
= 46/3 * -3 / 14
Ankur must have either forgotten or neglected the negative sign in the divisor
The correct option which describes Ankur's error is: Ankur found that the quotient of a positive number and a negative number is positive.
Given that,
Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
We have to find,
Which best describes his error?
According to the question,
The two [tex]15\dfrac{1}{3}[/tex] and [tex]-4\dfrac{2}{3}[/tex] number are mixed fractions.
Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
Then,
Convert the equation into an improper fraction,
[tex]= \rm \dfrac{15\dfrac{1}{3}}{-4\dfrac{2}{3}} \\\\\ Convert \ into \ improper \ fraction\\\\= \dfrac{\dfrac{15\times3+1}{3}}{\dfrac{-4\times 3+2}{3}} \\\\[/tex]
Now simplify the equation,
[tex]= \dfrac{\dfrac{46}{3}}{\dfrac{-10}{3}} \\\\\\ = \dfrac{\dfrac{46}{3} } {\dfrac{3}{-10}} \\\\\\ = \dfrac{-3}{14}[/tex]
The mistake he has committed, while dividing two fractions, he must have forgotten that one of the fractions which is in the denominator bears a negative sign before it.
Ankur forgot to put the negative sign before 3.
Hence, The correct option which describes Ankur's error is: Ankur found that the quotient of a positive number and a negative number is positive.

Lenny makes $55,000 and is getting a $2,500 raise per year. Karl makes $62000, with a $2,000 raise per year. Which inequality shows how many years, y, will it take for Lenny to earn more than or the same salary as Karl. 55000x + 2500 ≤ 62000x + 2000 55000 + 2500x < 62000 + 2000x 55000 + 2500x ≤ 62000 + 2000x 55000 + 2500x ≥ 62000 + 2000x
Answer:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]
Step-by-step explanation:
Given
Lenny:
Base Earnings = $55000
Raise = 2500 yearly
Karl:
Base Earnings = $62000
Raise = 2000 yearly
Required
Determine the inequality that takes years for Lenny to earn more or exact as Karl
Let y represent years:
Earnings = Base Earnings + Raise * Years
First, we need to determine Lenny's earning:
[tex]Lenny: 55000 + 2500 * x[/tex]
[tex]Lenny: 55000 + 2500x[/tex]
Next, we determine Karl's earning
[tex]Karl: 62000 + 2000 * x[/tex]
[tex]Karl: 62000 + 2000x[/tex]
To determine the required inequality, we have:
[tex]Lenny \geq Karl[/tex]
This gives:
[tex]55000 + 2500x \geq 62000 + 2000x[/tex]

Deez clothing is having a discount of 40% on all shirts let X represent the regular price of any show in the store enter an expression that can be used to find the sale price of any show in the store I know
Answer:
0.6X
Step-by-step explanation:
Given that :
Discount on shirt = 40%
Regular price of shirt = X
The sales price of shirt after applying the discount will become :
Regular price - discount on price
X - (40% of X)
X - (0.4x)
= 0.6x
Hence.the sales price of shirt will be : 0.6x
