Answer 1: 5x + 4
Answer 2: 9m + -10y
Step-by-step explanation:
To simplify 3x + 9 + 2x − 5, you have to find the like terms which are 3x and 2x, and 9 and -5. So you get 3x + 2x + 9 - 5 which gives you the result of 5x + 4. Now to simplify 7m + 2 (m − 5y), you have to distribute first, so 7m + (2) (m) + (2) (−5y) which gives you 7m + 2m + −10y. So now you just have to add. 7m + 2m = 9m and then you have -10y so basically the answer is 9m + -10y.

Moira borrowed $4,500 from her grandfather to pay for her first year of college. Three years later, she repaid the $4,500 along with an interest of $243. What was the annual interest rate? Round your answer to one decimal place.
9514 1404 393
Answer:
1.8%
Step-by-step explanation:
The effective rate can be found using the simple interest formula.
I = Prt . . . interest of principal P at annual rate r for t years
r = I/(Pt) . . . . solve for r
Using the given numbers, we have ...
r = 243/(4500·3) = 0.018 = 1.8%
The annual interest rate was 1.8%.

Josh made $253 for 11 hours of work. At the same rate, how many hours would he have to work to make $299
Answer:
The answer is 13.
Step-by-step explanation:
Divide 253 by 11. This gives you the total he makes within an hour, which is 23. Next add 253 and 23 together. This gives you 276. Add 23 again and you get 299. Since you added 23 together twice, that's two extra hour of work. Finally, add 11 and 2 and you get 13.
How much water does Ms. Maryna need to add to 60g of sugar to make a syrup that is 20% concentrated?
Answer:240
Step-by-step explanation:You get 240 because 60X4 is 240. to get the 4, you need to use 100-20, then therer would be 80. 80 divided by 20 is 4, which is the amount of water.
Ms. Maryna needed 240g water to add to 60g of sugar to make a syrup that is 20% concentrated
Given that,
Ms. Maryna need to add to 60g of sugar to make a syrup that is 20% concentrated.
We have to determine,
How much water does she need.
According to the question,
Ms. Maryna need to add to 60g of sugar to make a syrup that is 20% concentrated.
If Maryna need 20% sugar by mass,
Then,
[tex]= \dfrac{20}{100} = \dfrac{1}{5}[/tex]
It is 1/5 of the total mass is sugar,
And ,
Total water needed is,
[tex]= 1-\dfrac{1}{5} \\\\=\dfrac{5-1}{5}\\\\= \dfrac{4}{5}[/tex]
It needed 4\5 times of water.
Then,
Maryna needed times as much water as sugar,
[tex]= \dfrac{4}{5} \times \dfrac{5}{1}\\\\= 4 \ times[/tex]
Maryna needed 4 times as much water as sugar.
Maryna need water to add in syrup = 4 × 60g = 240g.
Hence, Maryna needed 240g of water to add to make a syrup.

Solve for r.
5r - -17r - 4r + -9 = 9
Answer:
r=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5r−−17r−4r−9=9
5r+17r+−4r+−9=9
(5r+17r+−4r)+(−9)=9(Combine Like Terms)
18r+−9=9
18r−9=9
Step 2: Add 9 to both sides.
18r−9+9=9+9
18r=18
Step 3: Divide both sides by 18.
18r/18 = 18/18
r=1
Which of these situations would follow the general rule for basis of inherited property?
Louis died on August 12, 2019, leaving his house to his sister, Etty.
On August 15, 2018, Leroy gave his brother Ralph appreciated stock. Leroy's brother Ralph died on February 16, 2019. Ralph's only heir was Leroy.
Mick died on June 30, 2019. He named his brother Emmett as the beneficiary of his 401(k) plan.
Janet died on January 1, 2019. At that time, she had an IRA with a balance of $32,640. She named her daughter, Emily, as the beneficiary of her IRA.
Amon the following situation 2 cases follow the general rule for basis of inherited property
Given , Statements of inheritance.
1. Louis died on August 12. 2019 leaving his house to his sister, Etty.
This is a case of inheritance of property as it justifies conditions of the definition of Inheritance of Property i.e Louis died and as a consequence his property is transferred to his sister which is her relative as per law. So, this is a valid case of inheritance. Even a person can transfer his property to some unrelated person, if he so mentions in his will.2. On August 15, 2018, Leroy give his brother Ralph appreciated stock. Leroy's brother died on February 16, 2019, Ralph's only heir was Leroy.
In this case, transfer of stock from Leroy to Ralph is outside the definition of inheritance, since Leroy was not died at that time. On second instance, when stock was transferred to Leroy after Ralph death in February 2019. It is a case of inheritance but it is the case of inheritance of stock, not inheritance of property. Stock of a company is not considered a property.3.Mick died on June 30, 2019. He named his brother Emmett as the beneficiary of his 401(k) plan.
A 401(k) plan is a retirement savings account that allows an employee to divert a portion of his or her salary into long-term investments. The employer may match the employee's contribution up to a limit.This is also a case of inheritance but not the case of inheritence of property. Retirement Savings account is not considered as property.
4.Janet died January 1, 2019. At that time, she had a IRA with balance of $32640. She named her daughter, Emily, as the beneficiary of her IRA.
This is also a case of inheritance but not the case of inheritence of property. IRA (Individual Retirement Account) is not considered as property.Know more about inheritance of property,

I dont get it.
Answer:

Step-by-step explanation:
This is wanting you to put a numerator that will make this fraction bigger then 2/4.
2/4 is greater then 1/6, so that won't work
2/4 is greater then 2/6, so that won't work either
2/4 is equal to 3/6 because they reduce to 1/2, so it won't work
2/4 is less then 4/6, this will work

Julie’s family took a 4-day trip. Julie’s mother wrote an equation to calculate their gas mileage, m, in miles per gallon. Let d = the number of total miles driven on the trip. Let g = the total number of gallons of gas used for the trip.
=
What was the gas mileage for the 4-day trip?
Answer:
[tex]m = 26[/tex]
Step-by-step explanation:
Given
See attachment for missing details
Required
Determine the gas mileage for the trip
First, we calculate the miles driven
[tex]Miles = 476 + 439 + 382 + 263[/tex]
[tex]Miles = 1560[/tex] --- d
Next, we calculate the amount of gas used
[tex]Gas = 15.0 + 13.5 + 15.4 + 16.1[/tex]
[tex]Gas = 60.0[/tex] ---- g
The gas mileage is then calculated as:
[tex]m = \frac{d}{g}[/tex]
[tex]m = \frac{1560}{60}[/tex]
[tex]m = 26[/tex]
Hence, the gas mileage is 26 miles per gallon
