Help me solve the following 5(2x+7)=

Ok so do 9 times itself 5 times so basically its this:

9*9*9*9*9

Next do the same but 3 times:

9*9*9

Exponents are not this:

9*3

But this:

9*9*9

Your answer:

59049/729

Another way to say it:

59049 over 729

There is your answer hope this helps

Answer:

9^2 (9 to the power of 2)

Step-by-step explanation:

Ok, this is how you find exponents:

Well, exponents are really just abbreviated multiplication, so to find the numerical value of 9^5 and 9^3, you need to multiply 9 by itself 5 times and 3 times, then divide.

9*9*9*9*9= 59049

9*9*9= 729

Then you divide: 59049/729= 81.

But the question asks to rewrite the answer using a single positive exponent, so now we simplify 81 into an exponent.

The square root of 81= 9

9*9=81

81 as an exponent= 9^2 (or 9 multiplied 2 times)

Another simple trick for solving exponents is to subtract the exponents:

9^5-9^3= 9^2 (5-3=2)

I hope this answer was helpful!

First move the 9 to the right side by subtracting 9 from both sides.

So we have x² + 6x ___ = 7 ___.

Notice that I created a space on each side of the equation.

The space is what we need to complete the square.

The number that goes in the spaces comes from half the coefficient of the

middle term squared, which in this case is half of 6, or 3, squared, which is 9.

So we add 9 to both sides of the equation.

Once we have completed the square, out trinomial will always factor as a binomial squared, and the number that goes inside the binomial will always be half the coefficient of the middle term of the trinomial.

So we have (x + 3)² = 16.

Now square root both sides to get x + 3 = ± 4

So x + 3 = 4 or x + 3 = -4.

Solving each equation from here, we get x = 1 or x = -7.

So our solution set is {1, -7}.

For this to work, whatever the white wax is, it needs to be 3 times as more as 5.

5x3=15

Answer:

i’ve done this before

Step-by-step explanation:

E and D

for every 12ml of red wax there’s 5 ml of white wax right? so you just multiply them at the same number to see if it matches.

12 x 5 = 60

5 x 5 = 25

12 x 3 = 36

5 x 3 = 15

Answer:

  (b)  60°

Step-by-step explanation:

The sum of angles in a pentagon is 540°, so you have ...

  90° +90° +150° +x +150° = 540°

  x = 540° -480°

  x = 60°

Answer: 2 / 3 = 0.666666666667

5n+2k = 25k or 7n but u have to divide by 2

25k divided by 2 = 12.5

7n divided by 2 = 3.5

12.5 + 3.5 = 16 therefore the answer is 16

Answer:

18 ft

Step-by-step explanation:

5 years for every 3 feet

30 years

Knowing this information, we can multiply or create an equation:

Multiplication:

5 x 6 = 30 so...

3 x 6 = 18

Equation:

5/3 = 30/x

5x = 90

/5    /5

x = 18

Step-by-step explanation:

Answer:

8°

Step-by-step explanation:

5w + 1° + 7w - 7° + 90° = 180° { being linear pair }

12w = 180° - 84°

12w = 96°

w = 96° / 12

w = 8°

Hope it helps :)

Answer:

5w+1+90+7w-7=180(linear pair)

12w=180-84

w=96/12=8

the correct answer is

3x = x + 5

3x - x = 5

2x = 5

x = 5/2

Answer:

105

Step-by-step explanation:

A straight line is 180 degrees so 180-75=105

Answer:

x= 105 degrees

Step-by-step explanation:

We know that the sum of x and 75 degrees is equal to 180 degrees.

So that means that x= 180-75 or x=105 degrees
