Answer:

hello there...

you know BODMAS for sure

First brackets then of then divi then multi then add and then subtract

going by BODMAS

we need to first of all multiply of -6 and 3

hence ans is multiplying -6 and 3

( option 1 Is wrong by the equation u sent if the equation is correct then ans is which given bur by options I think equation is wrong becoz I don't see divide symbol)

Answer:

x=61.71428 or 61 5/7

Step-by-step explanation:

We can use a ratio to solve

7 pieces              12 pieces

-----------------   = ---------------

36 seconds          x seconds

Using cross products

7x = 36*12

7x = 432

Divide by 7

7x/7 = 432/7

61 5/7

x=61.71428

Answer:

b=12

Step-by-step explanation:

Perimeter=2*(l+b)

64=2*(20+b)

b=12

Answer:

The width is 12 feet

Step-by-step explanation:

If the length is 20 feet, the other side must be 20 feet as well. The perimeter is the addition of all sides of a rectangle. Length: 20 on one side, 20 on other side. Subtract the length from total perimeter and you get 24 feet remaining. Divide 24 by 2. 12 feet for the width.

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = - 20

Distribute the minus sign

4x - x +4 = -20

Combine like terms

3x+4 = -20

Subtract 4 from each side

3x+4-4 = -20-4

3x = -24

Divide by 3

3x/3 = -24/3

x = -8

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = -20

~Simplify

4x - x + 4

~Subtract 4 to both sides

3x = -24

~Divide 3 to both sides

x = -8

Answer:

D. 769.7 ft^3

Step-by-step explanation:

because area of a solid is area of the base times the height, so to find the area of the base, it is pi*r^2(3.14*7^2), and that equals to 153.94, times that by 5 and you get 769.7 ft^3

Answer:

7.20 dollars

Step-by-step explanation:

1 1/4 can be expressed as 5/4 ((1*4+1) /4)

If price of 5/4 pound of turkey = $9

Price of 1 pound of turkey = $9 / (5/4)

( Same way you'd divide the price of 2 pounds by 2 to get the price of 1 pound)

$9 / (5/4) = $7.2

Answer:

144 degrees

Step-by-step explanation:

We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:

(n-2)(180) = ?

(10-2)(180) = ?

(8)(180) = 1440.

Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).

1,440/10 = 144

               = 144 degrees

AP = arithmetic progression, which is the same as arithmetic sequence

d = common difference

Notice how we scale up the d terms d, 2d, 3d, counting up by 1 each time.

So that must mean 25 is the same as 20+4d

20+4d = 25

4d = 25-20

4d = 5

d = 5/4

d = 1.25

and therefore,

We could convert these to fraction form, but I find decimal form is easier in this case.

Answer: 320

Step-by-step explanation:

Step 1) Identify Number of options for each set

For the entree, you have 4 options, for the sides, you have 4 options, and for the drink you have 5

Step 2) Find all possible outcomes

4 options for the entree × 4 options for the first side × 4 options for the second side × 5 options for the drink

Step 3) Solve

4 × 4 × 4 × 5 = 320

Answer:

-3

-7/3

Step-by-step explanation:

Let u=x+2

We need to now solve 3u^2+4u+1=0 for u.

I'm going to try factoring. 3u (u)=3u^2 and 1(1)=1 so I'm going to try factored form (3u+1)(u+1).

Since 3u(1)+1(u)=4u, we are done.

Since (3u+1)(u+1)=0, then either 3u+1=0 or u+1=0.

Let's solve u+1=0 by subtracting 1 on both sides which obtains for us that u=-1.

Let's solve 3u+1=0 by subtracting 1 and then dividing both sides by 3 which obtains for us u=-1/3.

Since u=x+2, we are down to just solving the following:

x+2=-1 and x+2=-1/3

Both equations require us to subtract 2 on both sides.

The solutions are

x=-1-2=-3 and x=-1/3-2=-7/3

Answer:

x=-1

Step-by-step explanation:

f (x)= -x + 8

Let f(x) = 9

9 = -x+8

Subtract 8 from each side

9-8 = -x+8-8

1 = -x

Multiply each side by -1

-1 = x

Answer:

Step-by-step explanation:

1kg=1000

Answer:

Answer is down below.

Step-by-step explanation:

To find the answer, we will have to use basic Algebra in order to view the solution.

Let the first number be = x

Let the second number be = x+2

Let the third number be= x+4

Let the fourth number be= x+6

(We did the x+ part because consecutive means following continuously..)

Now let's put the equation:

x+x+2+x+4+x+6 = 1052

Let's add all the variables and numbers separately in order to simplify:

4x+12 = 1052

Subtract 12 on both sides.

4x = 1040

Divide 4 on both sides

x = 260

Now, we know the value of x. Let's put it in our numbers.

Let the first number be = x = 260

Let the second number be = x+2 = 262

Let the third number be= x+4 = 264

Let the fourth number be+ x+6 = 266

Now, let's double check to see if our answers are correct.

260+262+264+266 = 1052

Valla! They are.

Answer:

Approximately [tex]50420[/tex] revolutions (rounded to the nearest whole number.)

Step-by-step explanation:

Convert the diameter of this wheel to meters: [tex]d = 30\; \rm cm = 0.30\; \rm m[/tex].

Circumference of this wheel:

[tex]\pi \, d = \pi \times 0.30\; \rm m \approx 0.942\; \rm m[/tex].

Distance travelled in one hour:

[tex]\begin{aligned}v \cdot t &= 13.2 \; \rm m \cdot s^{-1} \times 3600\; \rm s \\ &= 47520\; \rm m\end{aligned}[/tex].

Number of revolutions required for covering that distance:

[tex]\displaystyle \frac{47520\; \rm m}{(\pi \times 0.30\; \rm m)} \approx 50420[/tex].
