Answer: the man is 58!

Step-by-step explanation: please mark brainliest

we could use this equation

168=400-4a         an a= uknown age

-400     -400

-232=-4a

divide by -4 on both sides to get the variable by itself

58=a

a=58

and to double check we can do this

168=400-4(58)     by susbtuting the variable

168=400-232

168=168     correct

Step-by-step explanation:

48=4x can be used to determine the miles covered by Trisha that is 12 miles.

Total distance covered comprises the sum of distances covered by individual entities. Sum means adding like terms in mathematics.

Given, the total number of miles covered by both of them, t= 48 miles

If miles covered by Trisha = x

Then, miles covered by Brandy = 3x (as Brandy drove three times as far as Trisha ).

The total distance covered comprises miles covered by Trisha as well as Brandy.

t=x+3x

On adding the like terms.

t=4x

Substituting t=48,

48=4x

Dividing 4 both sides of the equation,

48/4=4x/4

12=x

x=12 miles

So, the Number of miles Trisha drove is 12.

Answer:  $486

Both expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, simplifying to 14. The equivalence exemplifies the Associative Property of Addition.

The question asks to determine whether the two expressions (20 – 4) – 2 and 20 – (4 – 2) are equivalent, and if so, to identify the property applied. To determine equivalence, we need to simplify both expressions. The first expression, (20 – 4) – 2, simplifies to 16 – 2 which equals 14. The second expression, 20 – (4 – 2), simplifies to 20 – 2 which also equals 14. Therefore, both expressions are equivalent, and the property applied here is the Associative Property of Addition, which allows us to change the grouping of the numbers we're adding (or subtracting, in this case) without changing the result.

Answer:

12% decrease

Step-by-step explanation:

think of 1000 as 100% and thin 880 as 88% subtract those 12%

The price decrease from $1000 to $880 represents a 12% decrease. This is figured out by taking the difference in price, dividing it by the original price, and then multiplying by 100%.

The percentage decrease is calculated by taking the difference in price divided by the original price, and then multiplying by 100 to get a percentage. In this case, the difference in price is the original price minus the sale price. This would be $1000 - $880 = $120. So, the formula would be ($120/$1000)*100. The calculated percentage decrease is 12%, meaning the price of the TV has been reduced by 12%.

We have two solutions :

[tex]x = \frac{3 + i \sqrt{3}}{2}\\\\x = \frac{3 - i \sqrt{3}}{2}[/tex]

The solutions to the quadratic equation x^2 - 3x + 3 = 0 can be found using the Quadratic Formula. The solutions are complex numbers: x = 3/2 ± (i*sqrt(3))/2.

The given equation is a quadratic equation of the form ax^2 + bx + c = 0. To find the solutions to this equation, we can use the Quadratic Formula: x = [-b ± sqrt(b^2 - 4ac)] / (2a).

Here a=1, b=-3, c=3.

Plugging these values into the formula,

we get x = [3 ± sqrt((-3)^2 - 4*1*3)] / (2*1).

Simplifying this equation will give us x = [3 ± sqrt((9 - 12)] / 2.

Now, note that the value under the square root is negative, indicating that the solutions will be complex.

Finally, we have the solutions:

x = [3 ± sqrt(-3)] / 2

= 3/2 ± (i*sqrt(3))/2, where 'i' is the imaginary unit.

The length of SK = 10 units while the length of BK = 8.6602 units.

Step-by-step explanation:

Step 1:

In the given triangle, there are two right-angles triangles with 60° angles. The central line BK is the opposite side for both the triangles. For triangle RK the hypotenuse's length is 10 m. Assume BK = x units and SK = y units.

Step 2:

So first we calculate the length of BK (x).

As we have the values of the angle of the triangle and the hypotenuse, we can calculate the sine of the angle to determine the value of x.

[tex]sin R = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{x}{10}.[/tex]

[tex]sin 60 = 0.86602, x = 0.86602 (10) = 8.6602 units.[/tex]

So x = BK = 8.6602 units.

Step 3:

So now we calculate the length of SK (y).

As we have the values of the angle of the triangle and the opposite side's length, we can calculate the sine of the angle to determine the value of y.

[tex]sin S = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{86.602}{y}.[/tex]

[tex]sin 60 = 0.86602, y = \frac{8.6602}{0.86602} = 9.999units = 10 units[/tex]

So y = SK = 10 units.

Answer:

x = 4, y = -5 OR (4, -5)

Step-by-step explanation:

Step 1:  Solve for y in the first equation

2x + y - 2x = 3 - 2x

y = 3 - 2x

Step 2:  Plug in that into the second equation to get x

4x + 3(3 - 2x) = 1

4x + 9 - 6x = 1

-2x + 9 - 9 = 1 - 9

-2x / -2 = -8 / -2

x = 4

Step 3:  Use x to find y

y = 3 - 2(4)

y = 3 - 8

y = -5

Answer:  x = 4, y = -5 OR (4, -5)

Step-by-step explanation:

Given:

Number of packets at the beginning of the day, Nb = 36 packets

Number of packets at the end of the day, Ne = 8 packets

A.

Number of packets sold, Ns = Nb - Ne

36 - Number of packets sold, Ns = Ne

8 = 36 - Ns

Ns = 28

B.

8 = 36 - Ns

8 = 36 - 28

Final answer:

The expression representing the number of juice boxes sold is 28 multiplied by x, where x is the number of juice boxes per package. Since x is unknown, the expression cannot be simplified further and remains as 28 × x.

Explanation:

Part A: Representing the Number of Juice Boxes Sold

To represent the number of juice boxes sold, let's denote the number of juice boxes in each package as x. The store started with 36 packages and ended with 8. We are looking for the number of juice boxes in the packages that were sold. The expression is:

28 × x (since 36 - 8 = 28, and 28 packages were sold)

Part B: Simplifying the Expression

To simplify the expression, we do not have further information to simplify 28 × x more because x represents an unknown number of juice boxes per package. The simplified expression remains as:

28 × x

Step-by-step explanation:

Hey there!

This is slope intercept form, where y=mx+b, where b is the y-intercept (where the line hits the y-axis) and the slope (rate of change).

If you wanted to graph this line, we can see that the y intercept in 35. Therefore, our line is going have one point on (0,35). Our slope is 15, which is positive, showing that our line will go up. Because the slope is fifteen, for every single increase of 1 there is in x, there will be an increase of 15 in y. This will give us points like (1,15) (2,30) (3,45). Therefore, this will be a very steep line.

8320 cubes can fit into the prism.

Solution:

Convert mixed fraction into improper fraction.

Length of the prism = 20 in

Width of the prism = 2 in

Height of the prism = [tex]3\frac{1}{4}=\frac{13}{4}[/tex] in

Volume of the prism = length × width × height

                                 [tex]$=20\times2\times\frac{13}{4}[/tex]

                                 = 130 in³

Volume of the prism = 130 in³

Length of the cube = [tex]\frac{1}{4}[/tex] in

Volume of the cube = length × length × length

                                 [tex]$=\frac{1}{4} \times\frac{1}{4} \times\frac{1}{4}[/tex]

                                 [tex]$=\frac{1}{64} \ \text{in}^3[/tex]

[tex]$\text{Number of cubes}=\frac{\text{Volume of the prism}}{\text{Volume of cube}}[/tex]
