Answer:

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

Step-by-step explanation:

Let x = Courtney's walking speed

then

(x + 1) = Brandi's walking speed

:

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time

6.5/x + 1 = 5/x

Cross multiply

6.5x= 5(x+1)

6.5x= 5x + 5

6.5x - 5x = 5

1.5x = 5

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

Note that:

(x + 1) = Brandi's walking speed

3.33mph + 1 = 4.33mph

Therefore,

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

The Courtney's walking speed = 3.33 mph. Brandi's walking speed = 4.33 mph.

We have given that,

[tex]6.5x - 5x = 5[/tex]

Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph

Let x = Courtney's walking speed

then (x + 1) = Brandi's walking speed

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time.

[tex]6.5/x + 1 = 5/x[/tex]

Cross multiply

[tex]6.5x= 5(x+1)[/tex]

Simplify parenthesis right side

[tex]6.5x= 5x + 5[/tex]

1.5x = 5

Isolate x.

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

(x + 1) = Brandi's walking speed

3.33 mph + 1 = 4.33 mph

Therefore,Courtney's walking speed = 3.33 mph

Brandi's walking speed = 4.33 mph

The integer that represents the altitude closer to sea level​ is 10.

Addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value. A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.

We are informed that Markers were placed at altitudes of 10 and 15 feet below sea level

Then we need to find the integer that represents the altitude closer to sea level​.

We can say that 10 is negative (below the sea level), and 10 is 10 spaces away from zero on the number line, meaning the answer could be |10|.

The sea level would be 0 and the 10 would be -10 and the 15 will be -15

Hence, the 10 is closer to the sea level.

Thus the integer that represents the altitude closer to sea level​ is 10,

Answer:

3.5 gallons

Step-by-step explanation:

140=40g

140/40=g

a) The car used 3.5 gallons of gas

b) The inverse function is g=m/40

In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f(x) produces the output. A function that has an inverse is called invertible and the inverse is denoted by f⁻¹

Given here, distance = 140 and  equation m=40g  then using the equation we get

140 = 40 ×g

g= 3.5 gallons

and the inverse function is given by g = m/40

Hence the car uses 3.5 gallons and we found the inverse function is g=40/m

The final statement is: 67 student tickets and 82 adult tickets were sold.

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: Total tickets =149 student ticket=$2 and adult ticket=$6

Tickets sold worth=$626

Let x tickets be bought by students and therefore 149-x be brought by adults then we have

2x+6(149-x)=626

-4x+894 = 626

         x=268/4

         x=67

∴ x=67 & 149-67=82

Hence,  67 student tickets and 82 adult tickets were sold.

Answer: 2/3, 3/4, 5/8, 5/6

Step-by-step explanation:

First,

We must turn all of them into denominators that can be divided by 1/2.

2/3 = 4/6. 3    1/3 = 2/6  

Now we see which is greater.  

2/3 > 1/2.  

3/4 > 1/2.

2/6 < 1/2.

1/3 < 1/2.

3/8 < 1/2.

5/8 > 1/2.

1/4 < 1/2.

5/6 > 1/2.

So the answers are 2/3, 3/4, 5/8, 5/6.

Step-by-step explanation:

In this question, we have to find how much more money Victoria is saving.

We know that Jacob saved $174 in 3 months.

We also know that Victoria saved $360 in 6 months.

Lets find how much money they save per month:

Jacob:

174 ÷ 3 = 58

Victoria:

360 ÷ 6 = 60

Jacob is saving $58 per month and Victoria is saving $60 per month.

This means that Victoria is saving $2 more than Jacob per month.
