Answers

Ok so all we have to do is $14.95 x 5.
Ans:$74.75

Answer: $71.76

A system of equation is shown.
5x+2y=245
y=x+6

Enter a numeric value to complete the solution of the system.

Answers

Answer:

y = 245 / 7, x = 29

Step-by-step explanation:

make both into ax + by = c format which is

Math:

5x + 2y = 245

-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.

[(Side Note) if both were positive then you would need to do

EX: - 5 (- x + y = 6)]

Continued:

7y = 275 ==> 7y/7 = 245/7

y = 245 / 7

Plug it in the most convenient one which has the equation y = x + 6

and tweak it a bit

x = y - 6

x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7

x = 203 / 7 ==> 29

I think he is right but the answer is 5x+2y=245.
Y=x+6

4^2÷ 2^1

B. 2

C. 0

D. 44

Answers

Answer:

A. 8

Step-by-step explanation:

Use PEMDAS

E for exponents (4^2)/(2^1)

4^2 = 4 * 4 = 16

2^1 = 2

D for division

16/2 = 8

So the answer is A

Hi!

Let's solve it together.

4^2 is just 4x4,

4 x 4 = 16

Next, 2^1.

2^1 is just 2, so the answer is 2.

Now, we divide 16 and 2.

16 ÷ 2 = 8

So, the answer is A.Hope this helps!~~~PicklePoppers~~~

Step-by-step explanation:

We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.

Enter your answer in the box.

Answers

Answer:

f(2) = -3

Step-by-step explanation:

Given the graph of a negative-sloped function:

In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.

Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan

Answers

Let x be the number of rolls sold by Sean.

We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.

Evan has sold 1/2x + 7 rolls.

Therefore, we have:

x + (0.5x + 7)  = 121

1.5x = 121 - 7

x = 114/1.5

x = 76

3x + 5y + 10
5x - 3y = -6

Answers

Answer:

3x + 5y + 10= 3

5x - 3y = -6

Step-by-step explanation:

1. m=-3/5

2. Simplifying

5x + -3y = 6

Solving

5x + -3y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 6 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 6 + 3y

5x = 6 + 3y

Divide each side by '5'.

x = 1.2 + 0.6y

Simplifying

x = 1.2 + 0.6y

Hope this helps

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

2.  Go 4 unit on right sides from Zero   to show  4

3.  Go 3 units on Left from zero to show opposite of 3

4.  Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 1
