8a -1+0.5b

Replace a nd b with the given values:

8(1/4) -1 + 0.5(10)

8 x 1/4 = 2

0.5 x 10 = 5

Now you have:

2 -1 + 5

2-1 = 1 +5 = 6

Answer is 6

Answer:

6

Step-by-step explanation:

Substitute the value of the variable into the expression and simplify.

Answer:

Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

           -38     -38

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

Answer:

Step-by-step explanation:

Question 1:

-7 = w + 5

- 5        - 5

-12 = w      

w = -12

Question 2:

-4p + 38 = 10

      - 38   - 38

-4p = -28

-----    -----       fraction bar... -4p divided by -4, -28 divided by -4

-4       -4

p = 7

Question 3:

-3 1/2 = -1 1/4b

- 7    =  - 5

-----      ----- b

 2          4

4        -7          -5          4

----  x -----   =  ------  x ----- b

-5        2           4         -5

-28

----     = b

-10

-28                       2          14

-----   divided by ----   =  -----

-10                        2          5

b = 2 4/5

A decrease in resistance creates an increase in current.

Step-by-step explanation:

Answer:

The total resistance decreases, so the current in the circuit increases.

The value after one year will be $535.

Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.

Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan. For example, a bank will pay you interest when you deposit your money in a high-yield savings account.

given:

amount= $500

interest rate = 7% on 3-year certificates of deposit.

So, after one year  the value will be

=500 x 7% + 500

=500 x 0.07 + 500

= 35 + 500

= $535

Hence, the value will be $535.

Answer:

Given : points 4  , 1 ,25  , opposite of 3 ,  -1/2

To Find : draw on Number Line

Solution :

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers  

On a number line the number increases as we move to the right and decreases as we move to the left.  

1 : Draw a line and mark some points at equal distance on it as shown in the figure below  Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3  and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]

From the graph, we have the following ordered pairs

(1,900) and (3,8100)

An exponential function is represented as:

[tex]p = ab^w[/tex]

At the point (1,900), we have:

ab = 900

At the point (3,8100), we have:

ab^3 = 8100

Divide both equations

[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]

Evaluate the quotients

[tex]b^2 = 9[/tex]

Take the square roots of both sides

b = 3

Recall that:

ab = 900

So, we have:

3a = 900

Solve for a

a= 300

Hence, the equation is:

[tex]p = 300 * 3^w[/tex]

Answer:

45 x + 55 x = 350

x increases until the total equals 350

45 + 55 = 100 = relative speed of approach

(B) traveling cars meet this equation's specifications (x = 3.5)

The correct statement is option B)

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: The equation as 45x+55x=350

A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.

Therefore the relative speed of the two trucks is given by 45+55=100

and let the time taken to meet is x then we can construct an equation as follows x=350/100

or,  45x+55x=350

Hence, The correct statement is option B)

Answer:

The positive integers between -7/3 and 5/2 are 1 and 2.

Step-by-step explanation:

"How many positive integers are between - 7/3 and 5/2?" can be written as "How many positive integers are between - 2 1/3 and 2 1/2?"  This rewriting makes it easier to identify the positive integers in question.  They are 1 and 2.

The number of positive integers between -7/3 and 5/2 is 3 (option H).

To determine the number of positive integers between -7/3 and 5/2, we need to find the positive integers greater than -7/3 and less than 5/2.

Converting -7/3 to a decimal, we have:

-7/3 ≈ -2.333

Converting 5/2 to a decimal, we have:

5/2 = 2.5

Now, let's check which positive integers lie between -2.333 and 2.5.

The positive integers greater than -2.333 and less than 2.5 are 0, 1, and 2.

Therefore, there are three positive integers between -7/3 and 5/2. The correct answer is option H. 3.

Answer:

8 hours.

Step-by-step explanation:

1. Subtract  640-224=416

2. Divide 416/52

3. 8 hours

8 hours.

Step-by-step explanation:

We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.

Let us find the remaining distance of trip by subtracting the distance already covered from total distance.

Remaining Distance = 640 miles - 224 miles

Remaining Distance = 416 miles

We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.

Time = 416 miles/52 miles/hour

Time = 416 miles/52 × hour/miles

Time = 416/52 hour

Time = 8 hours

Therefore, Max have left 8 more hours to drive.
