A car traveled 25 miles of a 200 mile trip to its destination. The car travels at a speed of 35 miles per hour. How many hours until the car reaches its destination? Respond to the two questions below and show all work.

Answers

Answer: 5 hours

Step-by-step explanation:

The car has already travelled 25 miles into the 200 miles that it is meant to travel.

The distance left is therefore:

= 200 - 25

= 175 miles

The car is travelling at 35 miles per hour.

The time left for travel is:

= Distance / Speed

= 175 / 35

= 5 hours

Natalie is making costumes each costume has 4 buttons that costs 3 cents and a zipper costs 7 cents how much does she spend on buttons and a zipper for each costume?

Answers

Answer:

19 cents

Step-by-step explanation:

Natalie buys 4 buttons at 3 cents each. She also buys 1 zipper at 7 cents

We are to find the total amount that she spends for each costume

I converted cents to dollars.

4 buttons at 3 cents = 4x0.03 (3 cents is 0.03 dollars)

= 0.12

The zipper = 7 cents = 0.07 dollars

The total amount she spent = 0.12+ 0.07

= 0.19 dollars = 19 cents

Therefore she 19 cents in total for each costume

4 buttons at

I am having trouble on algebraic expressions and numerical expression what is the easiest way to solve my problem and im in 6 th grade

Answers

Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.

Step-by-step explanation:

First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).

For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.

While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.

Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.

For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Best Buy is having a HUGE sale. All items are 60% off. How much will you pay for a tv that originally cost $1200 including 5% sales tax?

Answers

Answer:

$480

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Original cost including sales tax = $1,200

Discount = 60%

So, we can calculate the cost of TV after discount by using following formula:

Cost of TV after discount = $1,200 - ( $1,200 × 60%)

= $1,200 - $720

= $480

Hence, Cost of TV after discount is $480.

segment with endpoints R(6,-2) and S(-3,-2).
O (1,2)
O (1.5, 2)
O (1.5, -2)
(3,-2)

Answers

Answer:

(1.5, -2)

Step-by-step explanation:

First subract -3 from 6 to find the total distance of the line segment.

6 - (-3)

Two negatives make a positive

6 + 3

9 units distance

Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.

-3 + 4.5

-3 + 3 + 1.5

(1.5, -2)

6 - 4.5

6 - 4 - 0.5

2 - 0.5

(1.5, -2)

The midpoint of segment RS is (1.5, -2).

Solve the system of equations using subtraction. y = -2x + 1 4x + 2y = -3 a. Infinity many solutions b. No solution c. (0,-5) d. (-5,0)

Answers

Given:

The given system of equation is:

[tex]y=-2x+1[/tex]

[tex]4x+2y=-3[/tex]

To find:

The solution of given system of equations using subtraction.

Solution:

We have,

[tex]y=-2x+1[/tex] ...(i)

[tex]4x+2y=-3[/tex] ...(ii)

First equation can be rewritten as

[tex]2x+y=1[/tex] (Adding 2x on both sides)

[tex]4x+2y=2[/tex] ...(iii) (Multiplying both sides by 2)

After subtracting (ii) from (iii), we get

[tex]4x+2y-(4x+2y)=2-(-3)[/tex]

[tex]4x+2y-4x-2y=2+3[/tex]

[tex]0=5[/tex]

This statement is false because [tex]0\neq 5[/tex]. It means, there is no value of x and y for which the given system of equations are true.

Therefore, the given system of equations has no solution and the correct option is b.

if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)

Answers

Answer:

2y + 2z

6x³+2x²-10 + 2x²-24

6x³+4x²-34 ■

Step-by-step explanation:

The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

What is Polynomial?

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.

Here, y = 3x³+x²-5 and z = x²-12

Now,

2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )

2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )

2 ( y + z ) = 6x³ + 4x² - 34

Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
