Osvaldo Matthew Part A) How much money will Jose have saved after 4 weeks? Part B) After 20 weeks, can Jose buy the skateboard? Explain why he can or why he cannot. 2.)Evaluate if k=8 and v=5. 6(5v - k)/2

Answers

Answer:

After 4 weeks, he will have $57

After 20 weeks, he will have $105

Step-by-step explanation:

6(5v - k) / 2

6(5(5) - 8) / 2

6(17) / 2

102/2 = 51

Answer: below

Step-by-step explanation:

Part A)  After 4 week he will have saved ... (45+3x4= $57)... 57 dollars

Part B) After 20 weeks... (45+3x20= 105)... i dont know if he can buy the skate board bc you never said how much the skateboard cost.

2. 6(5v-k)/ 2

6(25-8)/2

150-48/2

102/2 = 51

(-a - b)x = 3a +3b.

Answers

Given:

The equation is

[tex](-a-b)x=3a+3b[/tex]

To find:

The value of x.

Solution:

We have,

[tex](-a-b)x=3a+3b[/tex]

It can be written as

[tex]x=\dfrac{3a+3b}{(-a-b)}[/tex]

[tex]x=\dfrac{3(a+b)}{-(a+b)}[/tex]

Cancel out the common factors.

[tex]x=\dfrac{3}{-1}[/tex]

[tex]x=-3[/tex]

Therefore, the value of x is -3.

what is the equation
example:: y=3/1x-6

Answers

Answer:

y = 4/6x - 4

Step-by-step explanation:

y = mx + b, m = slope and b = y intercept

Rise over run

Rise = +4

Run = +6

This means the slope is 4/6.

The y intercept is at -4.

Now, plug in the numbers for y = mx + b

y = 4/6x - 4

I'm not sure if this dividing,multiplying,subtracting or adding but for adding i got 6 as my answer.I don't know if this the correct answer but its better than having no answer right?

Answer:

It depends... look at the bottom of my explanation

Step-by-step explanation:

[tex]5\frac{1}{3}=\frac{31}{3}[/tex]   — I converted this to an improper fraction to make this easier; the 30 added to the 1 in the numerator comes from multiplying 5 by the denominator, 3, to create an equivalent number.

³¹/₃ ÷ ²/₃  — Now we divide the two fractions.

³¹/₃ × ³/₂  — Dividing by one fraction is the same as multiplying by its reciprocal

³¹/₁ × ¹/₂  — One fraction has a 3 in its numerator, the other in its denominator. These two "3" values cancel out

31 ÷ 2  — simplifying the resulting expression

³¹/₂ = 15.5  — two other ways to rewrite it; 15.5 comes from dividing 31 by 2

Now, she can't make part of a batch... could she? If she can, it's 15.5. If she can't, she can make 16 or 15 batches depending on how you round.

That's a judgment call. But I hope you understand this better! Have a great day!

two turkey burgers and a bottle of water cost $3.25. If three turkey burgers and a bottle of water cost $4.50,What is the cost of tw bottles of water?

Answers

Answer:

$1.50

Step-by-step explanation:

let b be the number of turkey burgers and w be the number of bottles of water.

[tex]2b + w = 3.25\\3b + w = 4.50[/tex]

becomes

[tex]3b + w = 4.50\\- (2b + w)=3.25[/tex]

[tex]b = 1.25[/tex]

substitute this into one of the original equations:

[tex]3b + w = 4.5\\3 * 1.25 + w = 4.5\\3.75 + w = 4.5\\w = 0.75[/tex]

two bottles of water equals 0.75 * 2 = 1.50

Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (-9,7), midpoint: (10, -3)

Answers

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]

So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.

[tex]x_{1} = -9[/tex]  and [tex]y_{1} = 7[/tex]

[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)

[tex]\frac{-9 + x_{2} }{2} = 10[/tex]           [tex]\frac{7 + y_{2} }{2} = -3[/tex]

-9 + [tex]x_{2}[/tex] = 20         7 + [tex]y_{2} = -6[/tex]

[tex]x_{2} = 29[/tex]                    [tex]y_{2} = -13[/tex]

endpoint is (29, -13)

Ethan reads 330 pages in 3/4 hour. How many pages does he read per hour?

Answers

Answer:

440

Step-by-step explanation:

330 divided by 3 times 4 is 440 and thats your answer.

Answer:  440  pages per hour

====================================================

Work Shown:

330 pages = 3/4 hour

4*(330 pages) = 4*(3/4 hour)  ........ multiply both sides by 4

1320 pages = 3 hours

1320/3 pages = 3/3 hours ...... divide both sides by 3

440 pages = 1 hour
