Answer:

x=21

Step-by-step explanation:

Hello

The solution to the equation is the numerical values ​​of the letters  for which equality is true.

To  find the value of x , you have to isolate x. to do this, you pass the 13 that is positive number to the other side of the equation,When you pass a positive number to the other side of the equation it passes as negative number.

x+13=34

x=34-13

x=21

The cost of one yard of fabric, based on given prices, is 6 dollars. This is calculated by taking the total cost and dividing by the total quantity, using the concept of ratio and proportion in mathematics.

This problem revolves around the concept of unit rates in mathematics, especially ratio and proportion. If 5/8 yards of fabric costs 3.75 dollars, then to find the cost of one yard, known as the unit rate, we need to divide the total cost by the total quantity. Therefore, the cost of one yard would be 3.75/(5/8), which equals 6 dollars. Hence, one yard of fabric costs 6 dollars.

Answer:

He had 0.8 liters to start with...

Step-by-step explanation:

0.44 is 55% of what? (what = x)

Equation: Y = P% * X

X = Y/P%

X = 0.44/55%

55% = 0.55

X = 0.44/0.55

X = 0.8

Answer:

ans is 0.8 liters

Step-by-step explanation:

Jackson drinks 0.44 liters of water, which was 55% of the water in the bottle.

Let X be the volume of water in the bottle to start.

55% of X = 0.44L

X = 0.44/55% = 0.44/55*100=44/55=4/5=0.8 liters

Find the LCM of the four numbers (3, 5, 8, 12)

3: 3

5: 5

8: 2 * 2 * 2

12: 2 * 2 * 3

LCM = 2 * 2 * 2 * 3 * 5

        = 120

Answer: 120 years

Final answer:

The planets will be in conjunction again after 15 years.

Explanation:

To determine when the planets will be in conjunction again, we need to find the least common multiple (LCM) of their orbital periods.

The orbital periods of the four planets are: 3 years, 5 years, 8 years, and 12 years.

To find the LCM, we can list the multiples of each of the numbers and identify the smallest number that appears in each list.

The multiples of 3 are: 3, 6, 9, 12, 15, ...

The multiples of 5 are: 5, 10, 15, 20, 25, ...

The multiples of 8 are: 8, 16, 24, 32, ...

The multiples of 12 are: 12, 24, 36, ...

The smallest number that appears in all lists is 15, so the planets will be in conjunction again after 15 years.

B because 30% of 1000 is 300

Answer:

Option B) $1000 would be correct.

Step-by-step explanation:

Jacklyn's employer matches 30% of Jacklyn's contributions to her 401(k) plan.

Let Jacklyn's contribution = x

Her employer's contribution = 30% of x = 300

= [tex]\frac{30x}{100}[/tex] = 300

= 30x = 300 × 100

= x = 30000 ÷ 30 = $1000

Jacklyn contributed $1000 to the 401(k) plan last year.

To solve this problem we propose the following equation:

1) [tex]b*h =45\\[/tex]  This is the equation of the area of a rectangle.

Where a and b are the sides of the rectangle

If b is the longest side, then

b is 80% longer than h.

2) [tex]b= h+0.8h\\[/tex]

Now we have 2 equations and two unknowns.

Therefore we solve the following equations

[tex]45=b*\frac{b}{1+0.8}\\[/tex]

[tex]b^2=45(1+0.8)[/tex]

[tex]b =\sqrt{45(1+0.8)}\\[/tex]

b = 9 feet

The length of the longest side is 9 feet.

The area of a rectangle is 45 ft^2

If the length of the long side of the rectangle is 80% greater than the short side of the rectangle.

Let the shortest side be the width (x)

Length of rectangle L = 80% greater than x

So length = 0.8 x + x

Length = 1.8 x

Area of the rectangle = Length * width

45 = 1.8x * x

[tex]45= 1.8x^2[/tex]

Divide by 1.8 from both sides'

[tex]25= x^2[/tex]

Take square root on both sides

x=5

so width of the rectangle = 5 feet

Length of the rectangle (longer side) = 1.8x = 1.8 * 5 = 9 feet

If it's $2.70 now, the cost would be $4.45 in 1995.

To find the 1995 cost of a movie ticket that was $2.70 in 1980, divide the 1995 CPI by the 1980 CPI and multiply by the 1980 price. The calculation yields a cost of approximately $4.99 for a movie ticket in 1995.

To calculate the cost of a movie ticket in 1995 using the Consumer Price Index (CPI) from 1980 to 1995, we can use the formula to adjust prices based on inflation:

Let's assume the cost of a movie ticket in 1980 was $2.70. The CPI for 1980 is 82.4, and for 1995 it is 152.4. We calculate the ratio as 152.4 / 82.4 = 1.8495.

Multiplying the 1980 ticket price by this ratio gives us:

$2.70 * 1.8495 = $4.99 approximately.

Therefore, the cost of a movie ticket in 1995, adjusted for inflation, would be about $4.99.

(2, 2 ), (- 2, 18 ), (0, 10 )

substitute the x-coordinate of each point into f(x) and if the value is equal to the y-coordinate then it is on the graph of f(x)

(- 18, 2 ) ⇒ y = 10 + 72= 82 ≠ 2

(- 10, 0 ) ⇔ y = 10 + 40 = 50 ≠ 0

(- 2, - 2 )⇒ y = 10 + 8 = 18 ≠ 2

(18, - 2 ) ⇒ y = 10 - 72 = - 62 ≠ - 2

(2, 2 ) ⇒ y = 10 - 8 = 2 ⇒ (2, 2 ) is on graph

(- 2, 18 ) ⇒ y = 10 + 8 = 18 ⇒ (- 2, 18 ) is on graph

(0, 10 )⇒ y = 10 - 0 = 10 ⇒ (0, 10 ) is on graph

(2, - 18 ) ⇒ y = 10 - 8 ≠ - 18

Answer:

Team A= 2b-5

Team B= b

Team C= b+80

The equation representing this scenario is (2b-5)+ b + (b+80)= 983

Step-by-step explanation:

Solving the equation b + (2b - 5) + (b + 80) = 983, we found that Team B scored 227 points. Therefore, Team A scored 449 points and Team C scored 307 points.

To represent the scenario mathematically, let's define the variable b as the total points scored by Team B. Then, we can express the points scored by the other two teams in terms of b:

The combined score for all three teams was 983 points. Thus, we can write the equation:

Simplify the equation step-by-step:

So, Team B scored 227 points.

Answer:

y = 7x/5 - 5

Step-by-step explanation:

m = 7/5

y - 2 = 7/5(x - 5)

y - 2 = 7x/5 - 7

y = 7x/5 - 5

slope intercept form: y = mx + b

Note the equal sign. what you do to one side, you do to the other. First, subtract 4x from both sides

4x - 3y = 15

4x (-4x) - 3y = 15 (-4x)

-3y = -4x + 15

Next, divide -3 from both sides to isolate the y.

(-3y)/-3 = (-4x + 15)/-3

y = (4/3)x - 5

y = (4/3)x - 5 is your answer

In mathematics, the term 'lower extremes' usually refers to the lower limit of a data set, also known as the minimum value. However, since the question specifically asks for 'values and actual numbers', we can assume that the student is referring to the values that represent the lower extremes in the data set. For example, if the data set is {3, 5, 1, 2, 7}, the lower extremes would be the values 1 and 2.
