Jose is saving money for a skateboard. His aunt gives him $45 to start with, and he saves $3 each week. The expression 45 + 3w gives the amount of money Jose saved after w weeks. 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
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.
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
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?
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

2] The DiPietro family ate at a restaurant.
The cost of the meal was $87.50.
The sales tax was 6% of the cost of the meal.
. They left a tip of 15% of the cost of the meal plus tax.
.
What was the total cost of the meal, tax, and tip?
SHOW WORK PLEASE
Answer:
$105.88
Step-by-step explanation:
87.50 * 0.15 = 13.13 this gets you the 15% tip
87.50 * 0.06 = 5.25 this gets you the 6% sales tax
87.50 + 13.13 + 5.25 = 105.88
[tex]x^{2}-8x+16=25[/tex]
Answer:
x = 9 ; -1
Step-by-step explanation:
[tex]x {}^{2} - 8x + 16 = 25 \\ x {}^{2} - 8x + 16 - 25 = 0 \\ {x}^{2} - 8x - 9 = 0 \\ (x + 1)(x - 9) = 0 \\ x = - 1 \\ x = 9[/tex]
Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (-9,7), midpoint: (10, -3)
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)

The correct answer is
2 cents.
Answer:
the answer is 0.0800320128 or in simplified form 0.08
Step-by-step explanation:
First you divide 12 ÷ 5.88 = 2.04081632653. Then you divide 20 ÷ 10.20 = 1.96078431373. Lastly you subtract 2.04081632653 - 1.96078431373 = 0.0800320128 or 0.08

juan piensa en un número si al doble del
número le aumenta 18 encuentra que es igual a 27, cual es el número?
Answer:
Step-by-step explanation:
el número es 4,5
es una ecuación lineal:
2x+18=27
2x=9
x=9/2
x=4,5
Answer:
el numero es 4.5
Step-by-step explanation:
numero = X
Doble del numero = 2X

2X + 18 =27
2x = 27 - 18
2X = 9
x = 9/2
x = 4.5

Ethan reads 330 pages in 3/4 hour. How many pages does he read per hour?
Answer:
440
Step-by-step explanation:
330 divided by 3 times 4 is 440 and thats your answer.
====================================================
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
Ethan's rate is 440 pages per hour.
