For this case we must find the solution of the following equation:

[tex]5x + 20 = 7 (x + 2)[/tex]

Applying distributive property on the right side of the equation we have:

[tex]5x + 20 = 7x + 14[/tex]

Subtracting 7x from both sides of the equation:

[tex]5x-7x + 20 = 14\\-2x + 20 = 14[/tex]

Subtracting 20 from both sides of the equation:

[tex]-2x = 14-20[/tex]

Different signs are subtracted and the major sign is placed.

[tex]-2x = -6[/tex]

Dividing between -2 on both sides of the equation:

[tex]x = \frac {-6} {- 2}\\x = 3[/tex]

Thus, the solution of the equation is[tex]x = 3[/tex]

[tex]x = 3[/tex]

The 1/3 of the adult dosage of the medicine will be 60 milligrams(mg).

A fraction is a number that is less than 1.

For example, a number 0.5 than is called a fraction number because it is less than 1.

Given that the adult dosage of the medicine is 180 milligrams(mg).

The 1/3 of the 180 milligrams(mg) will be

⇒ 180×1/3

⇒ 60 hence, 60 milligrams(mg) is one-third of adult dosage.

To find 1/3 of the adult dosage of 180 mg, you simply divide by 3, which results in a dose of 60 mg. This method ensures safe and accurate medication dosing.

If the adult dosage of the medicine is 180 milligrams (mg), then 1/3 of the adult dose can be calculated by dividing the adult dose by 3. So, you would perform the following calculation:

1/3 of 180 mg = 180 mg / 3 = 60 mg.

Therefore, 1/3 of the adult dosage of the medicine is 60 mg.

The mile symbol 'm' was commonly used before the widespread adoption of the metric system. The total miles taken by Ashlynn to ride her bike to school and home in 40 days is 160.

A mile is defined as the unit of length which is exactly equal to 5280 feet or 1760 yards and it is standardized as exactly 1609.344 meters. It is the largest unit which is commonly used to measure the distance between places that are far from each other.

Here the total miles covered by the bike is 2 + 2 = 4

The total miles covered by Ashlynn = 4 × 40 = 160

A mile is a customary unit of distance. It is commonly used to express the distance between cities, roads and the lengths of the rivers. The symbol of mile is denoted as 'mi'.

Thus the total miles is 160.

The small sign's perimeter is 36 inches

Answer:

Julie worked 18 hours at Job A and 17 hours at Job B.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Rate per hour at Job A = US$ 6.10

Rate per hour at Job B = US$$ 7.40

Hours at Job A = x

Hours at Job B = 35 - x

Total of hours worked by Julie = 35 hours

Total weekly earnings = US$ 235.60

2. How many hours did she work at each job the week that she made $235.60?

For finding the result, we will use the following formula:

6.10x + 7.4 (35 - x) = 235.60

6.10x + 259 - 7.4x = 235.60

-1.3x = 235.60 - 259 (Subtracting 259 to both sides)

-1.3x = - 23.40

x = -23.4/-1.3 (Dividing by -1.3)

x = 18

Julie worked 18 hours at Job A, so she worked 17 (35 - 18) hours at Job B.

3. Proof that x = 18 is correct.

6.10x + 7.4 (35 - x) = 235.60

6.10 (18) + 7.4 (35 - 18) = 235.60

109.80 + 125.80 = 235.60

235.60 = 235.60

It's proven that x = 18 is correct.

Answer:

Step-by-step explanation:

Let x represent the number of hours worked at Job A and 35-x represent the number of hours worked at Job B.

($6.10 × x) +$7.40 × (35-x) =$235.60

Solving for x

$6.10x + $259 - $7.40x = $235.60

Collect like terms and solve for x

$6.10x-$7.40x=$235.60-$259

-$1.3x=-$23.4

x=18hours for Job A while 35-x=17hours for Job B

Answer:

10,000 cups

Step-by-step explanation:

Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2

Let's suppose a cup of regular ice cream would have 100 parts of fat.

The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.

If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it

These numbers won't change if we used another number instead of 100 in the example shown.

The points located 5 units from the point M (-6, 6) are (-1, 6), (-11, 6), (-6, 11) and (-6, 1).

To find a point located 5 units from point M in any direction, you can use the coordinates of point M and adjust them based on the distance.

If point M is located at (-6, 6), and you want a point 5 units away, you can choose a direction (left, right, up, or down) and adjust the coordinates accordingly.

For example, if you want a point 5 units to the right of M, you add 5 to the x-coordinate:

[tex]x_{new[/tex] = -6 + 5 = -1

So, a point located 5 units to the right of M is (-1, 6).

If you want a point 5 units to the left of M, you subtract 5 from the x-coordinate:

[tex]x_{new[/tex] = -6 - 5 = -11

So, a point located 5 units to the left of M is (-11, 6).

Similarly, the y-coordinate can be modified for points 5 units above or below M.

For example, if you want a point 5 units to the top of M, you add 5 to the y-coordinate:

[tex]y_{new[/tex] = 6 + 5 = 11

So, a point located 5 units to the top of M is (-6, 11).

If you want a point 5 units to the bottom of M, you subtract 5 from the y-coordinate:

[tex]y_{new[/tex] = 6 - 5 = 1

So, a point located 5 units to the bottom of M is (-6, 1).

Ratio of PQC to ABC is 2:9.

Step-by-step explanation:

In ΔBRQ and ΔBPC

∠BQR = ∠BCP (given) and ∠B is common for both triangles, so from AAA similarity ΔBRQ and ΔBPC are similar.

⇒ BQ : QC = BR : RP = 2 : 1    →(1)

now draw perpendiculars from points A and P to BC line segment. Call the projected points as A' and P'.

It is clear that lines AA' and PP' are parallel. So in ΔBPP' and ΔBAA' we have AAA similarity with common angle at B.

⇒PP' : AA' = BP : BA = 2 : 3    →(2) (∵ AP : PB = 1 : 2)

area of ΔPQC = 0.5×PP'×QC

area of ΔABC = 0.5×AA'×BC

area of ΔPQC : area of ΔABC = (0.5×PP'×QC)/(0.5×AA'×BC)

                                               =(PP'/AA')×(QC/BC)

                                               =(2/3)×(1/3) (∵ from (1) and (2))

                                               =2/9.

∴ Ratio of PQC to ABC is 2:9

so basically 35*12 wouuld be what u would pay for a year

so 420 dollars is for one year- and yet u got a 700 dolllar loan so u actually are only paying 420 dollars which is 280 interest

Step-by-step explanation:

Answer:

60%

Step-by-step explanation:

The monthly rate is:

There are 12 months in a year, so the annual rate is:

12 × 0.05 = 0.6

The annual interest rate is 60%.

Answer:

Jack is five. so, it's A

Step-by-step explanation:

subtract 4 from both sides of the equation. You can cancel out the four on the left, and get 40 on the right (since you took four away from 44.)

Then, divide by 8 on both sides. The eight is canceled out on the left. eight goes into 40 five times, meaning a=5.

The correct option is (A) 5. To find Jack's age, subtract 4 from both sides of the equation 8a + 4 = 44 and then divide by 8. This results in a = 5, meaning Jack is 5 years old.

To solve the given equation, 8a + 4 = 44, for Jack's age, we first need to isolate the variable a, which represents Jack's age. This can be done by first subtracting 4 from both sides of the equation to undo the addition.

8a + 4 - 4 = 44 - 4

8a = 40

Next, we divide both sides of the equation by 8 to undo the multiplication and solve for a:

8a / 8 = 40 / 8

a = 5

Therefore, Jack's age is 5 years old, which corresponds to option A.
