Answer:

Step-by-step explanation:

You have to set each runner's plan equal to each other because they are equal in the end. You start with 7 miles for Angelo and 4 miles for Marc.

x is a variable that is multiplied by the number of weeks it takes for both runners' distances to be equal. So multiply x by the miles increased every week.

Marc = Angelo

2x + 4 = x + 7

x = 3

In 3 weeks each runner will run 10 miles for the week.

To find when Angelo and Marc will be running the same distance and what that distance will be, set up and solve equations.

To find out in how many weeks Angelo and Marc will be running the same distance, we can set up an equation. Let's assume the number of weeks is x. Angelo's distance can be represented by the equation 7 + 1x, and Marc's distance can be represented by the equation 4 + 2x. To find when their distances are equal, we can set the two equations equal to each other and solve for x.

Setting the equations equal: 7 + 1x = 4 + 2x

Simplifying the equation: x = 3

Therefore, Angelo and Marc will be running the same distance in 3 weeks. To find the distance, we can substitute the value of x back into either of the original equations. Let's use Angelo's equation: 7 + 1(3) = 10

So, Angelo and Marc will be running 10 miles in the same distance.

Answer:

B

Step-by-step explanation:

In probability, "AND" means to multiply and "OR" means to add.

Here they want probability of steel penny ( P(s) ) "OR" probability of lincoln penny ( P(l) ).

Let's find the individual probabilities and "ADD" them.

P(s) = 5/50 (since there are 5 steel pennies and there are 50 coins in total)

P(l) = 5/50 (since there are 5 lincoln pennies and there are 50 coins in total)

So probability of 5 steel penny and 5 lincoln penny = 5/50 + 5/50 = 10/50 = 1/5

1/5 is equal to 20%, correct answer is B

Answer:

x=102

Step-by-step explanation:

9x-54=8x+48

subtract 8x from both sides

x-54=48

add 54 to both sides

x=102

Answer:

x = 102

Step-by-step explanation:

9(x + -6) = 8(x + 6)

Reorder the terms:

9(-6 + x) = 8(x + 6)

(-6 * 9 + x * 9) = 8(x + 6)

(-54 + 9x) = 8(x + 6)

Reorder the terms:

-54 + 9x = 8(6 + x)

-54 + 9x = (6 * 8 + x * 8)

-54 + 9x = (48 + 8x)

Solving

-54 + 9x = 48 + 8x

Add '-8x' to each side of the equation.

-54 + 9x + -8x = 48 + 8x + -8x

Combine like terms: 9x + -8x = 1x

-54 + 1x = 48 + 8x + -8x

Combine like terms: 8x + -8x = 0

-54 + 1x = 48 + 0

-54 + 1x = 48

Add '54' to each side of the equation.

-54 + 54 + 1x = 48 + 54

Combine like terms: -54 + 54 = 0

0 + 1x = 48 + 54

1x = 48 + 54

Combine like terms: 48 + 54 = 102

1x = 102

Divide each side by '1'.

x = 102

That's is correct answer

Answer:

The truck original price is $16.00 and the car price is $5.00.

The truck sale price is $8.00 and the car price is $10.00.

Step-by-step explanation:

We need to find the original price of the truck (T) and car (C)

Sale price of the truck is 50% so that means it is half the original price.

Now let's see the equations we can come up with there:

At sale price:

[tex]T + C = \$13.00\\\\4T + 2C = \$42.00[/tex]

We can solve this through substitution.

Using the first equation, we can come up with an equation for one of the missing variables.

[tex]T + C =\$13.00\\\\C = \$13.00 - T[/tex]

We can use this equation on the second one, to solve for one variable. [tex]4T + 2C = \$42.00\\\\4T + 2(\$13.00-T) = \$42.00\\\\4T + \$26.00 - 2T = \$42.00\\\\4T - 2T = \$42.00 - \$26.00\\\\2T = \$16.00\\\\\dfrac{2T}{2}=\dfrac{\$16.00}{2}\\\\T = \$8.00[/tex]

The sale price of the model truck is $8.00.

Now can use this on the first equation again.

[tex]T + C = \$13.00\\\\\$8.00 + C = \$13.00\\\\C = \$13.00 - \$8.00\\\\C = \$5.00[/tex]

The sale price of the model car is $5.00.

Because it is 50% off on both models, the original price is twice the sale price. So we can solve it by multiplying the sale prices by 2.

Original price of model truck: $8.00 x 2 = $16.00

Original price of model car: $5.00 x 2 = $10.00

Answer:

The truck's original is $16. The sale price is $8. The car's original is $10. It's sale is $5.

Answer:

3^-3

Step-by-step explanation:

27 = 3^3

so

1/ 27= 1 / 3^3 = 3^-3

To write the fraction \( \frac{1}{27} \) as an expression with a negative exponent, you can use the property of exponents that states \( a^{-n} = \frac{1}{a^n} \), where \( a \) is any non-zero real number and \( n \) is a positive integer.
Applying this property to \( \frac{1}{27} \), we can see that the fraction is the reciprocal of \( 27 \) raised to the first power. Thus, we rewrite the expression \( \frac{1}{27} \) by flipping the position of \( 27 \) to the numerator and making the exponent negative:
\( \frac{1}{27} = 27^{-1} \)
So, \( 27^{-1} \) is the same as \( \frac{1}{27} \). When you calculate \( 27^{-1} \), you get the value of approximately \( 0.037037037037037035 \), which represents the decimal equivalent of the fraction \( \frac{1}{27} \).

Comstock Nut Company can make 400 packages of peanuts by dividing the total weight of peanuts (500 pounds) by the weight of each package (1.25 pounds). Ounces or grams would be suitable to measure a handful of peanuts.

To calculate how many packages Comstock Nut Company can make, we simply divide the total weight of the peanuts by the weight of each package. They have 500 pounds of peanuts and each package weighs 1 and 1/4 pounds (which is the same as 1.25 pounds).

Number of packages = Total weight of peanuts ÷ Weight per package

Number of packages = 500 pounds ÷ 1.25 pounds/package

When you divide 500 by 1.25, you get 400. Therefore, Comstock Nut Company can make 400 packages of peanuts.

When it comes to choosing the best unit of measurement, for a handful of peanuts, we would typically use ounces or grams since they are small quantities that don't weigh much, similar to how Jeffrey should use ounces to label packages of steak when most are less than a pound.

Answer:

990 deers is ONE possible answer.

Step-by-step explanation:

Since we don't know anything else than the perimeter, we don't know the exact dimensions of the park.

For example, it could be 10 x 11 miles, perimeter is 42, but the area is 110 sq miles.

It could also be 9 x 12 miles, perimeter is again 42, but the area is now 110 sq miles.

It could be a 1 x 20 miles park, perimeter is again 42, but the area is just 20 sq miles.

And it could be many other dimensions scenarios.  That affect of course the calculation result.

For this answer, I'll assume the park is 10x11 miles, for an area of 110 sq miles.

Since the estimation is that there's 9 deeps for square mile... that means that for a park measuring 10x11 miles, there would be 990 deers (9 * 110).

Step-by-step explanation:

The zero of the function is the point on the x- axis where the graph crosses

That is x = - 5

Answer: OPTION D

Step-by-step explanation:

The zero of the function is the intersection of the function with the x-axis.

A function intersects  the x-axis when the value of y is zero ([tex]y=0[/tex])

Then, you can observe in the graph attached that the function intersects the x-axis at the point (-5,0), where the x-coordinate is -5 and the y-coordinate is 0:

[tex]x=-5\\y=0[/tex]

Therefore, you can identify that the zero of the function shown in the figure is:

[tex]x=-5[/tex]

This matches with the option D.

Answer:

y + 1 = - [tex]\frac{1}{3}[/tex](x - 4)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 5 is in this form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex]

The equation of a line in point slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here (a, b) = (4, - 1), thus

y - (- 1) = - [tex]\frac{1}{3}[/tex](x - 4), that is

y + 1 = - [tex]\frac{1}{3}[/tex](x - 4) ← in point- slope form
