A gear rotates 8 times every 15 seconds. based on the information which of the following is wrong

Answer:

48

Step-by-step explanation:

2x + 3 = 15

2x = 15-3

2x = 12

x = 12 ÷ 2

x = 6

8x = 6 × 8

8x = 48

Answer:

15.

Step-by-step explanation:

L + L + W + w = 66

L= w+3

W+3 + w+3 + w + w = 66

4xw + 6 = 66

4xw = 66 - 6

4xw = 60

W + W +w +w =60

W= 60/4

W=15

L = 15+3 (=18)

15+15+18+18=66

Answer:

3.5 = y

Step-by-step explanation:

2.5y + 6 = 4.5y - 1

2.5y + 7 = 4.5y

7 = 2y

3.5 = y

Check:

2.5y + 6 = 4.5y - 1

2.5(3.5) + 6 = 4.5(3.5) - 1

2.5(3.5) + 7 = 4.5(3.5)

8.75 + 7 = 15.75

15.75 = 15.75

Answer:

[tex]y=3.5[/tex]

Step-by-step explanation:

[tex]2.5y+6=4.5y-1[/tex]

Start by subtracting [tex]6[/tex] from both sides of the equation:

[tex]2.5y=4.5y-7[/tex]

Subtract [tex]4.5y[/tex] from both sides of the equation:

[tex]-2y=-7[/tex]

Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]-2[/tex]:

[tex]y=3.5[/tex]

_

Check your solution by substituting the solved value of [tex]y[/tex] ([tex]3.5[/tex]) into the initial equation:

[tex]2.5(3.5)+6=4.5(3.5)-1[/tex]

[tex]8.75+6=15.75-1[/tex]

[tex]14.75=14.75[/tex]

Since both sides of the equation are equal to each other, our solution is correct!

Answer:

p + 240 ≤ 360; p ≤ 120

Step-by-step explanation:

The inequality that shows the number of more passengers to carry by plane is 240 + x = 360.

The number of more passengers is 120.

It is a statement of an order relationship

- greater than,

- greater than or equal to,

- less than,

- less than or equal to between two numbers or algebraic expressions.

We have,

Number of passengers in a plane = 360

Number of passengers in a day = 240

The inequality represents the number of more passengers that can carry:

240 + x = 360

Where x is the number of more passengers.

Find x.

240 + x = 360

Subtract 240 on both sides.

240 + x - 240 = 360 - 240

x = 120

Thus,

The inequality that shows the number of more passengers to carry by plane is 240 + x = 360.

The number of more passengers is 120.

Answer:

m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer

Step-by-step explanation:

okay, so you want to get m

because m is divided by 3, to counter it, you multiply both sides by three

-m/3 = -4

-m/3 times 3 =-4 times 3

because 1/3 times 3 =1, and -4 times 3 = -12, you get

-m = -12

then, divide both sides by - (because you want positive m)

and you get m = 12

the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Answer:

The second line where 3 multiplies -m/3=3 times -4

Step-by-step explanation:

Multiplying a negative by a postive will result in negative so multiplying a negative by a negative will result in a postive. Multiplying 3 by -m/3 will result in -m so you should multiply -m/3 by -m so the varuable will be postitive. The answer would be m=12. Hope this helps.

Answer:

3x3x3x3

Step-by-step explanation:

1. 4 is the exponent so you would put down (-3) 4 times but, since the -3 is in parentheses it automatically becomes positive.

2. So, instead of writing (-3)x(-3)x(-3)x(-3) or -3x-3x-3x-3 you would write 3x3x3x3.

Answer: The satellites speed was 190 kilometers per minute.

Step-by-step explanation:

The formula for speed is calculated as:

Speed = Distance/Time

where,

Distance = 380 kilometers

Time = 2 minutes

Speed = Distance/Time

Speed = 380km/2min

Speed = 190km/min

The satellites speed was 190 kilometers per minute.

Therefore, the correct answer is C.

Answer:

$53.14

Step-by-step explanation:

Add-on-rate = 16%

Cost = $1,578 + Sales tax = 5%(5% of $1578 = $78.90)

Time = 3 years

Total amount borrowed = 1578 + 78.90 = $1656.90

Charges = 16%

So, 16% of 1656.90

= 16/100 * 1656.90

= $265.10

Total amount would be = 1656.90 + 256.10 = $1913

No. of months in 3 years = 36months

∴ Monthly payment = [tex]\frac{1913}{36}[/tex]

Answer:

y=3x+2

Step-by-step explanation:

y=mx+b

We have our m, which is slope, but we need our y intercept, b.

Substitute your slope, x, and y into the formula and solve for b.

5=3(1)+b

5=3+b

-3 -3

2=b

Now we can plug into equation.

y=3x+2

Answer:

y = 2/5x - 1/5

Step-by-step explanation:

The first step is to find the slope. We can do this by doing y2- y1/x2 - x1, you can name any number 1 or 2 as long as the x and y are right.

-1 - (-3)/-2 - (-7) = 2/5

Now that we know that the slope is 2/5 we can use the formula

y - y1 = m(x - x1)

y + 3 = 2/5(x +7)

y + 3 = 2/5x + 2 4/5

y = 2/5x - 1/5

Answer:

$160

Step-by-step explanation:

Answer:

1. a. 110

because 5 less than 35 is 30 and 5 less than 10 is 5. it would only make sense for 5 less than 110 is 105

7. D. 54

every other number in the equation is one less (8,7,6,5)

and inbetween those the number is multiplied by 3 (2×3=6, 6×3=18) so then 18×3 =54

the middle left. D. 27

every other one is multiplied by 2 (2×2=4, 4×2=8, 8×2=16) but the first one is multiplied by 3. (1×3=3 3×3=9 9×3=27 27×3=81)

11. A.11

it adds 6 every other (17+6=23, 23+6=29)

for every other first one it adds 4. (7+4=11, 11+4=15, 15+4=19)

12. D. 18

for every other it adds 2.(4+2=6, 6+2=8)

for every other second it adds 6. (6+6=12, 12+6=18, 18+6=24)

15. D. 49

for every other it subtracts 6 (67-6=61, 61-6=55, 55-6=49)

the every other second it divides in half. (32÷2=16, 16÷2=8, 8÷2=4)

18. D. 17

for every other it adds 2.(13+2=15, 15+2=17, 17+2=19)

for every other second it subtracts 2. (21-2=19, 19-2=17, 17-2=15)

Answer: 7 dollars per gallon

Answer:

Ok

Step-by-step explanation:

So, the domain is the set of all possible values that can be inputted into the function. Or where is function on the x axis is the function defined. The range is similar but on the y axis. In this case, the function you have there appears to go on to infinity (I assume that is what the arrow means) and so the range would be [-1, -infinity) and domain [1, infinity). Brackets are important here because it shows that the function is still defined at point (1,-1), therefore, I used [ bracket symbol (I again assumed that the shaded in black dot at point (1,-1) means that the function is closed at that point and that when it is not shaded in, it is open). I feel like I didn't explain very well but good luck and hopefully someone does a better job that what I did.
