Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 10}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ \frac{4}{x} = \frac{28}{70}} [/tex]

Do cross multiplication

[tex] \longrightarrow{ \sf{28x = 4 \times 70}}[/tex]

Multiply the numbers: 4 and 70

[tex] \longrightarrow{ \sf{28x = 280}}[/tex]

Divide both sides by 28

[tex] \longrightarrow{ \sf{ \frac{28x}{28} = \frac{280}{28}}} [/tex]

Calculate

Answer:

x= 1.¯17948¯¯

Explain:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

your answer is incorrect

Step-by-step explanation:

0.2 times (x+3) = 0.2x + .6

4(2x-3) = 4 x 2x + 4 x -3 = 4 x 2x + -7 = 6x + -7

0.2x + .6 - 6x + -7 = -5.8x + -7

because you cannot combine terms that are not alike, then your final answer would have to be -5.8x + -7 because you did not give us what x is equal to.

Answer:

300

Step-by-step explanation:

(-3)(-100)= -3 x -100

A NEGATIVE MULTIPLIED BY A NEGATIVE WILL ALWAYS GET A POSITIVE SO MAKE -3 INTO 3 AND TURN -100 INTO 100.

Now you have 3 x 100 which gets you 300

Answer:

20 yards

Step-by-step explanation:

The area of a square is calculated by multiplying its height by its base. Because they are the same in a square, the area of a square is obtained by squaring one of its sides. Let's call the sides 'x'. Then we can express the area of the garden as x^2=400.

From here we simply need to square root both sides which gives us:

x=20

Therefore the length of one side of the garden is 20 yards.

Answer:

Step-by-step explanation:

solution: x=3;

extraneous solution: x=-1

The solution is 3 and the extraneous solution is -1.

The modulus function is the function which gives the magnitude or absolute of the number in the variable.

|x|=x if x>0

    -x if x<0

     0 if x=0

So according to question,

|7x+21|=14x

case-1: if 7x+21>0

⇒7x>-21

⇒x>-21/7

⇒x>-3

if 7x+21>0 , Using the modulus function property

|7x+21|=14x

⇒7x+21=14x

⇒14x-7x=21

⇒7x=21

⇒x=21/7

⇒x=3 which is also x>-3

x=3 is the solution

case-2:  if 7x+21<0

⇒7x<-21

⇒x<-21/7

⇒x<-3

if 7x+21<0 ,  Using the modulus function property

|7x+21|=14x

⇒-(7x+21)=14x

⇒-7x-21=14x

⇒14x+7x=-21

⇒21x=-21

⇒x=-21/21

⇒x=-1 for which x<-3 is not true

x=-1 is an extraneous solution.

Therefore the solution is 3 and the extraneous solution is -1.

Answer:

$500 net profit in 4 weeks

Step-by-step explanation:

+$50 a day, 5 days a week, -$500 every 4 weeks

1. solve for initial profit in 4 weeks

5 profitable day*4 weeks= 20 days Tom makes a profit

20 days*$50= $1000 in 20 days

2. subtract rent from initial profit

1000-500= $500

Step-by-step explanation:

Answer:

m=5

Step-by-step explanation:

Firstly we know we are solving for M.

So we start like this.

[tex]3(5m - 7) + 4 = 8m + 1 [/tex]

use the distributive property to multiply 3 by 5m-7=

[tex]15m - 21 + 4 =8m + 18[/tex]

Add -21 and 3 to get -17

[tex]15m - 17 = 8m + 16[/tex]

subtract 8m from both sides

[tex]15 m - 17 - 8m = 18[/tex]

combine 15m and -8m to get 8m

[tex]7m - 17 = 18[/tex]

Add 17 to both sides

[tex]7m = 18 + 17[/tex]

Add 18 and 17 to get 35

[tex]7m = 35[/tex]

Divide both sides by 7

[tex]m = \binom{35}{7} [/tex]

Divide 35 by 7 to get 5

[tex]m = 5[/tex]

I have to pay 12.5% more than the original price.

The decimal representation is 0.125.

The fractional representation is 112.5/100.

The percentage is the value per hundredth.

Given there is a 12.5% of tax on items purchased in Arlington.

Assuming the original price of a product is 100 dollars.

∴ The price of the product with 12.5% of tax is,

= (100 + 12.5)/(100)×100.

= 112.5 dollars.

∴ I have to pay 112.5 dollars for every 100dollar product.

So, the percentage of the original price that I have to pay is (112.5/100).

= 12.5%.

The decimal value of 12.5% is (12.5/100) = 0.125.

The fractional representation is 112.5/100.

Answer:

  17 feet by 65 feet

Step-by-step explanation:

If w represents the width of the garden, then 6w-37 is the length. The perimeter of a rectangle is twice the sum of length and width, so the perimeter is ...

  164 = 2(w +(6w -37)) = 14w -74

  238 = 14w

  238/14 = w = 17

__

  6w-37 = 6·17 -37 = 65

The width of the garden is 17 feet; the length is 65 feet.

When x= 3 then y= 17

When x = -3 then y = -7

$0.20 x 50min = $10

$15 + $10 = $25

So, it's 50 minutes.

Answer:

50 batches

Step-by-step explanation:

A bag of flour = 5 pounds of flour

A batch of cookies = 0.10 pounds of flour

How many batches can be made with the 5-pound bag?

Batch of cookies in 5 pounds of flour = Total pounds of flour / flour needed per batch of cookies

= 5 pounds / 0.10 pounds

= 50 batches of cookies

50 batches of cookies can be made with 5 pounds of flour

Answer:

x=12

Step-by-step explanation:

14/21=16/(x+12)

cross multiply

14(x+12)=16(21)

14x+168=336

14x=336-168

14x=168

x=12 (so the side would be x+12=24)

You could also see that 14 is 2/3 of 21, so 16 has to be 2/3 of x+12.  That means x+12 would have to equal 24.  If you take the 12 away from 24, x=12.
