8/15÷4/5 Help Anyone

Answer:

x= 13

Step-by-step explanation:

3x-4+20= 55

combine like terms:

3x+16= 55

subtract 16 from both sides:

3x = 39

divide 3 to both sides:

x= 13

Answer:

Answer:

y=5x

Step-by-step explanation:

Answer:

{x,y}={31,4}

Step-by-step explanation:

x-8y = -1  x-6y = 7

Answer:

first we find the value of 'y' so

x-8y=-10+8y

x=-10+8y

-2(-10+8y)-6y=-24

20-16y-6y=-24

20-22y=-24-20

-22y=-44

y=2

then also we can find the value of 'x'

-2x-6y=-24

2x-6(2)=-24

2x-12= -24

2x= -24+12

x= -12

Answer:

You can buy a maximum of 13 erasers/pencils.

Step-by-step explanation:

Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

Answer:

B

Step-by-step explanation:

Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.

= Fixed essential expenses + Variable essential expenses

= 1,292 + 420

= $1,712

Sam needs to save three times his expenses:

= 1,712 x 3

= $5,136

= Amount to be saved / Amount saved monthly

= 5,136 / 210

= 24 months approximately.

________________________________________________________

The question is:

Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?

a. $1,712; approximately 8 months

b. $5,136; approximately 24 months

c. $6,486; approximately 30 months

d. $2,162; approximately 6 months

Answer:

x ≥ - 3

Step-by-step explanation:

Step 1:

- 7x - 13 ≥ 8       Equation

Step 2:

- 7x ≥ 21      Add 13 on both sides

Step 3:

x ≥ 21 ÷ - 7      Divide

Answer:

x ≥ - 3

Hope This Helps :)

Answer:     x≤−3

Step-by-step explanation:

So first you  -7*x-13-(8)≥0

then you are supposed to pull out like the factors  -7x - 21  =   -7 • (x + 3)

then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got  x ≤ -3 So I really hoped this helped :)

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex].

Where,

[tex] \theta = 260 [/tex]

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = [tex] \frac{260}{360} \times \pi 8.7^2 [/tex]

Area of sector = [tex] \frac{260 \times \pi 75.69}{360} [/tex]

Area of sector = 171.74 cm² (approximated)

Answer:

Step-by-step explanation:

So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.

(3/5) / 4

Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.

So (3/5) * (1/4) is 3/20 which is .15 pounds

Answer:

I got 5^10 x 2^14 x 3

Step-by-step explanation:

1. Do a tree to find 480 as a product of its prime factors

2. You should get 480= 5x2x3x2x2x2x2

3. 10 expressed as a product of its prime factors is 5x2

4. so 10^9 expressed as a product of its prime factors would be

5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

5. You can then write out 480x10^9 as a product of its prime factors

5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

6. change this to use powers

5^10 x 2^14 x 3

N = 5^(10) × 2^(14) × 3

This is about prime factors

By definition, a prime factor is a factor of a number and that factor is also a prime number.

A prime number is one that is divisible by only itself and 1.

The number we have is; 480 × 10^(9)

Now, let's list the prime factors or 480 and they are;

2, 3, 5

Now, using these prime factors alone to get 480, we have;

5 × 3 × 2 × 2 × 2 × 2 × 2 = 480

In powers, gives;

5 × 3 × 2^(5)

Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;

(5 × 2)^(9)

Expanding this gives; 5^(9) × 2^(9) = 10^(9)

Thus;

480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)

This gives;

5^(10) × 2^(14) × 3

Answer:

54

Step-by-step explanation:

What the shorthand is telling you is wherever you see an x on the right, you put in -8

f(x) = 6(1- x)

f(-8) = 6(1 - - 8)

f(-8) = 6(1+8)

f(-8) = 6*9

f(-8) = 54

Answer:

17:21

Step-by-step explanation:

The ratio 68:84 in its simpliest form is;

68:84 (Since it can divided by 2 perfectly);

34:42 (We also divide this by 2 )

17:21

17:21 is the final answer and it can be divide any further. Since 17 is a prime number, it can't be divided and also 21 can be divided by 3 but 17 can't be divided by 3 so we leave the final answer like that.

-  -4(-3n - 8) = 104

Divide both sides by -4!

-4(-3n - 8) over -4 = 104/-4

Simplify!

-3n - 8 = -26

Add 8 to both sides!

-3n - 8 + 8 = -26 + 8

Simplify!

-3n = -18

Divide both sides by -3!

-3n/-3 = -18/-3

Step-by-step explanation:

From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:

= Difference in error / Actual value × 100

= (107 - 92) / 107 × 100

= 15/107 × 100
