Answer:

9x

3⁻⁶ x (3⁴ ÷ 3⁰)²

3⁻⁶ x (3⁴)²

3⁻⁶ x (3^8)

1/3^6x (3^8)

9x

Answer:

x = 12

Step-by-step explanation:

9x + 7 and 115 are alternate exterior angles and are congruent, then

9x + 7 = 115 ( subtract 7 from both sides )

9x = 108 ( divide both sides by 9 )

x = 12

Answer: 6 2/3

Step-by-step explanation:

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:

= 10/3

= 3 1/3

She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:

= 3 1/3 × 2

= 10/3 × 2

= 20/3

= 6 2/3

Answer:

x=5 , y=-2

Step-by-step explanation:

rearrange y=3x-17 to -3x+y=-17

then subtract to get x or y

     x+y=3

- (-3x+y=-17)

       4x=20

         x=20/4

         x=5

then sub in the x value into one of the equations

for x+y=3

    (5)+y=3

          y=3-5

          y= -2

Answer:

Step-by-step explanation:

Look at 3%2At%2B7=%28+-8+%29.

Moved these terms to the left  %28 +8+ %29

It becomes 3%2At%2B7%2B _green%28+8+%29=0.

Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.

Added fractions or integers together

It becomes 3%2At% 2B % 28+15+%29=0.

Look at highlight_red%28+3%2At%2B15+%29=0.

Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0

It becomes highlight_green%28+0+%29=0.

Result: 0=0

This is an equation! Solutions: t=-5.

Answer: t= -1/3

Step-by-step explanation:

3t+7=-8

subtract 7 from 7 and 8 (this cancels out the 7)

left with 3t = -1

divide 3 into 3t and -1

the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3

Answer: See explanation

Step-by-step explanation:

From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.

The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:

136b > 360

b > 360/136

b > 2.65

Therefore, Me Robinson must bike for more than 2.65 hours

Answer:

  0.666... = 6/9 = 2/3

Step-by-step explanation:

The repeating decimal 0.666... can be turned to a fraction as follows.

Let x represent the value of the number. Then 10x is ...

  10x = 10(0.666...) = 6.666...

Subtracting x gives ...

  10x -x = 6.666... - 0.666... = 6.000...

  9x = 6

Dividing by 9 and simplifying, we have ...

  x = 6/9 = 2/3

__

It can be worthwhile to remember that  1/9 = 0.111... repeating.

Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating

and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating

Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...

  2 ÷ 3 = 0.6666667 or 0.66666666667

or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.

Additional comment

A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

Answer:

£6956.52

Step-by-step explanation:

Given data

R=5%

A= £8000

T= 3 years

P=???

The compound interest is

A=P(1+r)^t

8000= P(1+0.05)^3

8000= P(1.05)^3

8000= P1.15

P= 8000/1.15

P=6956.52

Hence she needs to invest £6956.52

Step-by-step explanation:

Answer:

X = -3

Step-by-step explanation:

Answer:

If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

When you solve for this, you'll get 100/3.

You can then substitute x for 100/3 and get the numbers.

Answer:

8 Hours

Step-by-step explanation:

Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.

4 people x 14 hours = House

56 hours = House

56 hours is required to paint a house.

7 people x H hours=  House

7 people x H hours = 56

(7 people x H hours)/ 7 = 56 / 7

You divide 7 on both sides to isolate H on one side.

H hours = 8

So H = 8 which is the amount of hours needed.

Step-by-step explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed

The answer for this is a. 90

Answer:

IJ = 68.6 feet

Step-by-step explanation:

In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=84°, and HI = 69 feet. Find the length of IJ to the nearest tenth of a foot.

We solve the above question using the Trigonometric function of Sine

sin x = Opposite/Hypotenuse

x = ∠H=84°

Opposite = IJ

Hypotenuse = HI = 69 feet.

Hence

sin 84 = IJ/69

Cross Multiply

IJ = sin 84 × 69

IJ = 68.62201078 feet

Approximately = 68.6 feet

Answer:

0.25 lawns

Step-by-step explanation:

The computation of the number of lawns each hour is shown below;

M represent the mowed

ANd, number of hours represent h

Also

M = 4h

That means one mowed = 4 hours

So for one hour = 1 ÷ 4 = 0.25 lawns

Answer:

x=10, x=-2

Step-by-step explanation:

x^2-5x-3x+15=35

x^2-8x-20=0

Multiply to -20, add to -8: -10, 2

(x-10)(x+2)=0

x=10, x=-2

Answer:

x = −2 or x = 10

Step-by-step explanation:

(x - 3)(x - 5) = 35

x^2 − 8x + 15 = 35

x^2 − 8x + 15 − 35 = 35 − 35

x^2 − 8x − 20 = 0

(x+2)(x−10) = 0

x + 2 = 0 or x − 10 = 0

x = −2 or x = 10

Answer:

Monthly salary= $4,228

Step-by-step explanation:

Giving the following information:

Fixed salary= $2,500

Sales commission= 10%

Sales= $24,600

To calculate the monthly salary, we need to use the following formula:

Monthly salary= fixed income + commission

Commission= (24,600 - 15,000)*0.18

Commission= $1,728

Monthly salary= 2,500 + 1,728

Monthly salary= $4,228
