Answer:
4.5454 seconds
Step-by-step explanation:
1.5 km is equal to 1,500 m
1,500 m divided by 330.0 m/s = 4.5454 s

8) v = -3
9) m = 4
Explanation:
8)
[First distribute the factored terms on the left side of the equation]
2(v + 4) + 3(4v + 5) = -19 →
2(v) + 2(4) + 3(4v) + 3(5) = -19 →
2v + 8 + 12v + 15 = -19 →
[Next, add the like terms together]
(2v + 12v) + (8 + 15) = -19 →
14v + 23 = -19 →
[Subtract 23 from both sides to isolate the constant term]
14v + 23 – 23 = -19 – 23 →
14v = -42 →
[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]
14v / 14 = -42 / 14 →
v = -3
9)
[Start by distributing the factored term on the left side of the equation]
2(m – 1) = 10 – m →
2m – 2 = 10 – m →
[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]
2m – 2 + m = 10 – m + m →
3m – 2 = 10 →
[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]
3m – 2 + 2 = 10 + 2 →
3m = 12 →
[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]
3m / 3 = 12 / 3 →
m = 4

Joan joined her school's band. She bought a viola for $72.21, and a song book
which was $7.25 with a $100 bill. How much change was Joan given?
Hello :D
To do this you need to add the cost of the violin and the song book.
$72.21 + $7.25 = $79.46
$100 - $79.46 = $20.54
The answer is $20.54. I hope this helps :)
Solve:
a. 5y – 3 = – 18
b. -3x – 9 = 0

d. 1 – 2(y – 4) = 5
Answer:
a. y = -3
b. x = -3
c. z = - 1
d. y = -7
Step-by-step explanation:
a. 5y - 3 = - 18
5y = -18 +3
5y = -15
y = -15/5
y = - 3
b. -3x - 9 = 0
-3x = 9
x = 9/-3
x = -3
c. 4 + 3(z-8)= -23

3z = -23 + 20
3z = -3
z = -3/3
z = - 1

PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE HELP DECIMAL WORD PROBLEM INTO EQUATION
Answer:
136 miles
Step-by-step explanation:
Write an equation to represent the cost of the rental, and then solve the equation to find the number of miles.
Let x = number of miles.
The total cost is the cost per mile plus the base fee.
1 mile costs $0.90
2 miles cost $0.90 * 2
x miles cost $0.90 * x, or simply 0.9x
The base fee is $16.95, so the total to rent for x miles is 0.9x + 16.95
The equation
c = 0.9x + 16.95
gives you the cost, c, for a rental of x miles.
We are told the total cost was $139.35. Replace c with 139.35, and solve for x, the number of miles.
139.35 = 0.9x + 16.95
Switch sides.
0.9x + 16.95 = 139.35
Subtract 16.95 from both sides.
0.9x = 122.4
Divide both sides by 0.9
x = 122.4/0.9
x = 136
Answer: 136 miles

[tex]\\ \sf\longmapsto 9x=27[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{27}{9}[/tex]
[tex]\\ \sf\longmapsto x=3[/tex]
Answer:
x = 3
Step-by-step explanation:
First, we know that the perimeter in total is 23. So, we need to make sure that all of the sides combined are 23. The equation becomes:
3x - 5 + 2x + 1 + 4x = 23
Let's simplify this.
3x + 2x + 4x - 5 + 1 = 23
Simplify again.
3x + 2x + 4x - 5 + 1 = 23
5x + 4x - 5 + 1 = 23
9x - 5 + 1 = 23
9x - 4 = 23
Now we have the simplified equation of 9x - 4 = 23. Now we must solve for x.
9x - 4 (+ 4) = 23 (+ 4)
9x = 27
9 9
x = 3
Now we can see that x = 3, which should be our answer. To make sure, let's plug it into the equation.
[3(3) - 5] + [2(3) + 1] + [4(3)] = 23
[9 - 5] + [2(3) + 1] + [4(3)] = 23
[9 - 5] + [6 + 1] + [4(3)] = 23
[9 - 5] + [6 + 1] + 12 = 23
4 + [6 + 1] + 12 = 23
4 + 7 + 12 = 23
11 + 12 = 23
23 = 23
As you can see, we got the answer 23 = 23. That indeed means that x = 3. Hope this helps!

Hey, can someone help me with 8 math problems of numbers in their prime factored form? I have no idea how to do this and my teacher didn't really explain very well, so this would be a big help!
Prime factorization is shows you the only way a number can be factored.
Here are some examples:
6 = 2 x 3
(2 and 3 are prime numbers) If you need to, search up a prime chart of numbers. Also prime numbers is technically how small you can get a number.
Here are some more examples:
12 = 2 x 2 x 3
45 = 5 x 3 x 3
now that you see what it looks like, you may be wondering how did factor those out? Well first find a divisible number. lets use this example;
Factor out 42.
first think of your times table, what two numbers get you to 42, I know that 6 times 7 does so now write it out:
42 = 6 x 7
Is this equation done?
No it is not, 6 can still be factored.
What two numbers get you the product of 6?
they are 3 and 2.
Now the final factored out equation looks like this:
42 = 3 x 2 x 7

I hope this helps!

Objective; Translating points
A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.
Algebracially:
[tex](x + h)[/tex]
where h is the amount of units we move right or left
and
[tex](y + k)[/tex]
where k is the amount of units we move up or down
For 1. We are asked to translate the figure 3 units up and 7 units to the left.
7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is
Our new coordinates
E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).
2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.
So our new coordinates is
T' (1,3)
U' (4,3)
V'(4,5)
W'(1,5)

To take a taxi, it costs $3.00 plus an additional $2.00 per mile traveled. You spend $20 on the taxi. How many miles did you go?
Answer: 8.5 miles
Step-by-step explanation:
Given information
Base fee = $3.00
Fee per mile = $2.00
Distance = x
Total money spend = $20
Set equation
3 + 2x = 20
Subtract 3 on both sides
3 + 2x - 3 = 20 - 3
2x = 17
Divide 2 on both sides
2x / 2 = 17 / 2
[tex]\boxed{x=8.5}[/tex]

Solve each equation 3m-3/5=2m-1/2
Answer:
m= 1/10
Step-by-step explanation:
1. Move the terms so that will be 3m - 2m=-1/2 + 3/5
2. Subtract the m values so that will be 3m - 2m= 1 or m
3. Calculate the sum.
4. So the answer will be m= 1/10. M because we subtracted 2 from 3 which make us 1 so we say it m and 1/10 by doing 1/2 + 3/5.
Answer:
Step-by-step explanation:
3m - 3/5 = 2m - 1/2
3m - 2m = 3/5 - 1/2
m = 0.1
To find 15, Beau found 32 = 9 and 4 = 16. He said that since 15 is between 9 and 16,15 must be between 3 and 4. He thinks a good estimate for 15 is 3+4 = 3.5. Is Beau's estimate high, low, or correct? Explain.
Answer:
Answer: His estimate was low
Step-by-step explanation:
It's true that √16 is 4 and that √9 is 3
for √15 :
[tex] \sqrt{15} = 3.9[/tex]
It's true that √15 lies between 3 and 4
[tex] \sqrt{15} : 3 < x < 4[/tex]
Estimated answer :
[tex] = 3.5[/tex]
Exact answer :
[tex] = 3.9[/tex]
Therefore, the error:
[tex] \delta x = 3.9 - 3.5 \\ \\ = 0.4[/tex]
Since error is less than 0.5, his estimation was moderate, [ low ]

Answer:
y=95
Step-by-step explanation:

180-85=95
y=95
Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x and y is 17 and 95, respectively.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.
The measure of ∠1 and ∠3 will be equal since the two angles are vertical angles. Therefore, we can write.
∠1 = ∠3
5x° = 85°
x = 85° / 5
x = 17°
Also, the sum of measures ∠1 and ∠2 will be equal to 180°, this is because the two angles form a pair of linear angles. Therefore, we can write,
∠1 + ∠2 = 180°
5x + y = 180°
Substitute the value of x,
5(17°) + y = 180°
85° + y = 180°
y = 180° - 85°
y = 95°
Hence, the value of x and y is 17 and 95, respectively.
