Simplify (12b*7) / (4b*5)

Mathematics

Answer:

Step-by-step explanation:

I am assuming that you meant the following:

 12b^7

------------

  4b^5

Note that " ^ " is the proper symbol for exponentiation, and " * " for multiplication.

12/4 = 3 and b^7 / b^5 = b^2.  Thus,

 12b^7

------------ = 3b^2 (or, better yet, 3b²).

  4b^5

➷ First, just divide the numbers:

12/4 = 3

When dividing values with exponents, you have to subtract the exponents:

7 - 5 = 2

Therefore, your answer would be option B. 3b^2

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the ta
Lelu [443]

Answer:

7.900 cm

Step-by-step explanation:

The computation of the diameter after using the tape is given below:

Since the circumference is 14.8 cm

And it would be decrease by 2.4 cm

So, the new circumference is

= 14.8 - 2.4

= 12.4 cm

Now the radius is

= 12.4 ÷ π

= 3.95

And, the diameter is

= 3.95 × 2

= 7.900 cm

Y= - x+2 Y=3x-4<br> Estimate the solution to the system of equations
IrinaVladis [17]

Answer:

x=\frac{3}{2}\\ y=\frac{1}{2}

Step-by-step explanation:

y=-x+2\\y=3x-4

Let's solve one of them for x.

y=3x-4

Add 4

y+4=3x

Divide by 3.

x=\frac{y+4}{3}

Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.

x=\frac{y+4}{3}

x=\frac{(-x+2)+4}{3}

x=\frac{-x+2+4}{3}

x=\frac{-x+6}{3}

Multiply by 3 to get rid of the denominator.

3x=-x+6

add x

3x+x=6

Combine like terms;

4x=6

Divide by 4.

x=\frac{6}{4}

Simplify.

x=\frac{3}{2}

Now that you found the value of x, replace it in any of the equations to find y.

y=-x+2\\y=-(\frac{3}{2})+2\\ y=-\frac{3}{2}+2

y=\frac{-3+2*2}{2} \\y=\frac{-3+4}{2} \\y=\frac{1}{2}

Proof:

y=3x-4\\\frac{1}{2}=3(\frac{3}{2})-4\\\frac{1}{2}=(\frac{9}{2})-4

\frac{1}{2}=\frac{9-4*2}{2}

\frac{1}{2}=\frac{9-8}{2}

\frac{1}{2}=\frac{1}{2}

The perimeter of a triangle is 42 yards. The first side is 5 yards less than the second side, and the third side is 2 yards less
Maru [420]
Let the second side be equal to x Then the first side is x-5 The third side will be x-5-2 = x-7 Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42 3x=44 X= 44/3 Therefore the second sides length is 44/3 The first sides length is 44/3 -5 = 29/3 The third side is 44/3 -7 = 23/3
