Answer:

x=19

Step-by-step explanation:

5(x+35)=9(300

5x+175=270

5x=270-175

5x=95

95/5=19X

Can you take a closer picture? I will put my answer in the comments if I can do it.

Answer:

The greatest common factor of 4 and 19 is 1

Step-by-step explanation:

Answer:

Greatest common factor of 4 and 19 is 1

Answer:

SAME AS THIS

Explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84

Answer:

the sale price would be $78

Step-by-step explanation:

add up all the prices to get 120

35% taken off of 120 is 78

Answer:

-15

Step-by-step explanation:

Answer:

1. x = 21°

2. x = 30°

3. x = 7°

5 x = 3

Step-by-step explanation:

Solving for x

1. 15+ 5x + 60° = 180°

75 + 5x = 180°

5x = 180 - 75

5x = 105

x = 105/5

x = 21°

2. These angle are vertical angles

Hence:

13x - 5 = 125°

13x = 125° + 5

13x = 130

x = 130/3

x = 30°

3. 8x - 1 = 55°

8x = 55 + 1

8x = 56

x = 56/8

x = 7°

5. These angles are angles in a straight line

17x - 1 + 130° = 180°

17x + 129° = 180°

17x = 180° - 129°

17x = 51

x = 51/17

x = 3°

Answer:

[tex]8 \sqrt{72} = 8 \sqrt{3 \times 3 \times 2 \times 2 \times 2} \\ = 8 \times 3 \times 2 \times \sqrt{2} = 48 \sqrt{2} [/tex]

Answer:

The answer of the addition is;

√2+√5

Step-by-step explanation:

Here, we want to evaluate the given sure

Basically, we want to add the two surds together

In the case of this question, since they have nothing in common, the addition of both will give the same results

Thus;

√2+√5 = √2+√5

Answer:

Area of gray region = [tex]8x^2+8x-7[/tex]

Step-by-step explanation:

The area covered by the furniture can be subtracted from the total area of the room to calculate the area of the gray region.

Total area of the room: [tex]13x^2+7x-2[/tex]

Area taken up by furniture: [tex]5x^2-x+5[/tex]

Area of gray region = total area of the room - area taken up by furniture

Area of gray region = [tex]13x^2+7x-2-(5x^2-x+5)[/tex]

Remember to distribute the negative sign:

Area of gray region = [tex]13x^2+7x-2-5x^2+x-5[/tex]

Combine like terms:

Area of gray region = [tex]8x^2+8x-7[/tex]

Answer:

8x^2+6x+3

Answer:

5

Step-by-step explanation:

1.24 times 3 = 3.72

.95 (the value of pence to a pound in decimal form) = 2.85

6.18 for the teapot

2.72+2.85+6.18=11.75

She now has £8.25 left (20-11.75).

8.25/1.57=the amount of plates she can buy: 5.25477707006, so 5 with some money left

Answer:

Yes

Step-by-step explanation:

It is true because the equation would be 1 is less than or equal to 3-(-4)

Answer:

y=2x+0

Slope:  

2

y-intercept:  

( 0, 0 )

Step-by-step explanation:

Slope intercept form: y=mx+b

Use the slope formula and the slope-intercept form to find the slope  m  and y-intercept  b .

Answer: $2.55

Step-by-step explanation:

He bought the second shirt for half off the first shirt's price. He therefore bought it at:

= 19.99/2

= $10.00

Total paid for both shirts is therefore:

= 19.99 + 10

= $29.99

Sales tax is 8.5% so he paid:

= 29.99 * 8.5%

= ‭2.54915‬

= $2.55

Answer:

0.853

Step-by-step explanation:

Explanation: Just like any of your two-step equations,

in this inequality,  start by isolating the x term which in this

case is -3x by subtracting 5 from both sides.

That leaves you with -3x < -24.

To get x by itself, divide both sides by -3 but watch out.

When you multiply or divide both sides of an inequality by a

negative number, you must switch the direction of the inequality sign.

So we have x < 8 and put your final answer in

set notation and it look like this → {x: x < 8}.

Answer:

2nd option is the right answer

Answer:

[tex]\huge\boxed{\sf x = 8a}[/tex]

Step-by-step explanation:

[tex]\sf \frac{3}{a} x - 4 = 20\\\\Add \ 4 \ to \ both \ sides\\\\\frac{3}{a} x = 20+4\\\\\frac{3}{a} x = 24\\\\Multiply \ both \ sides \ by \ a\\\\3x = 24 * a\\\\Divide \ 3 \ to \ both \ sides\\\\x = 24a / 3\\\\x = 8a\\\\\rule[225]{225}{2}[/tex]

Hope this helped!
