25 + r = -5 (2+8r) + 6r

Answer:

8 km

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

40 / 5 = 8km

12 ≤ x

Step-by-step explanation:

Answer:

[tex]\$843.67[/tex]

Step-by-step explanation:

Let's break the price changes down:

Initial price: $896

On sale for 12%, meaning the computer will be 100-12=88% of the original price:

New sale price [tex]\implies896\cdot 0.88=\$788.48[/tex]

Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.

Final price [tex]\implies 788.48\cdot 1.07\approx \boxed{\$843.67}[/tex]

Let's solve for x.

−x+9y=−5

Step 1: Add -9y to both sides.

−x+9y+−9y=−5+−9y

−x=−9y−5

Step 2: Divide both sides by -1.

−x ÷ −1 = −9y−5 ÷ −1

x=9y+5

THE ANSWER FOR THE OTHER EQUATION: (x-5y=1)

Let's solve for x.

x−5y=1

Step 1: Add 5y to both sides.

x−5y+5y=1+5y

x=5y+1

Answer:

x=5y+1

I hope this helped I was a little confused on what your problem meant...so if this is not what you asked for just lmk so I can fix it for you :)

Answer:

120 different outcomes

Step-by-step explanation:

Selecting a year in the last decade ; this means selecting a year from from the last decade :

Number of years jn decade = 10

Selecting a month of the year : number of months in a year = 12

Hence, we have :

10 * 12 = 120 different outcomes

Answer:

[tex]x = \frac{d - b}{a - c} [/tex]

Answer:

36

Step-by-step explanation:

Square roots have a neat property: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b}[/tex] provided a and b are positive real numbers.

This property is what's behind simplifying square roots.  You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.

Example: [tex]\sqrt{20}=\sqrt{4\times5}=\sqrt{4}\sqrt{5}=2\sqrt{5}[/tex].

In this problem, both factors are perfect squares.

[tex]\sqrt{9\times144}=\sqrt{9}\sqrt{144}=3\times12=36[/tex]

Answer:

Solution given:

[tex] \sqrt{9 \times 144} [/tex]

[tex] \sqrt{3² \times 12²} [/tex]

±(3*12)

±36 is a required answer.

Answer:

15, 80

Step-by-step explanation:

1) I am assuming the first picture is a 90 degree angle total, because the question can't be solved without that assumption.

  90 - 75 = 15

  x = 15

2) The whole angle is 180 so 180 - 75 - 25 = CAD

  CAD = 80

Answer:

15° and 80°

Step-by-step explanation:

for the first one since its a right angle then its equal to 90 degrees

90-75 = 15     x=15°

for the second one since the line is a straight line then put it equal to 180

25+75+x=180

100+x=180

x=80°

Answer:

3/25

Step-by-step explanation:

Answer:

4/5

Step-by-step explanation:

the numerator of fraction is 1 less than its denominator. If the numerator is increased by 4 and the denominator is increased by 5, the new fraction becomes equivalent to 4/5. what is the original fraction?

Let n = numerator

d = denominator

n = d - 1

[tex]\frac{d - 1}{d}[/tex]

[tex]\frac{d - 1 + 4}{d + 5}[/tex] = [tex]\frac{4}{5}[/tex]

[tex]\frac{d + 3}{d+ 5}[/tex] = [tex]\frac{4}{5}[/tex]

cross multiply

5(d + 3) = 4(d + 5)

5d + 15 = 4d + 20

d = 5

n = d - 1

5 - 1 = 4

original fraction 4/5

Answer:

d ≈ 15.8

Answer:

r = - 2.5

[tex]r=-2\frac{1}{2}[/tex]

Step-by-step explanation:

21r - 7 - r + 5 = - 52

20r - 2 = - 52

20r - 2 + 2 = - 52 + 2

20r = - 50

20r ÷ 20 = - 50 ÷ 20

r = - 2.5

Hello! answer: 97

Step-by-step explanation:

You must get a 97 To pass with a final grade of 88 because 97 + 84 + 92 + 87 + 80 = 440 amd when you divide by 5 you get 88 so therefore you muss get a 97 to average with a 88 score Hope that helps!

Answer:

4.71

Step-by-step explanation:

First you use the formula : C=2πr (this is the formula for the perimeter of a full circle)

The radius is half the length of a circle. Half of 3 is 1.5.

2 x π x 1.5 = 9.42

Now we divide answer by 2 since its only half a circle

9.42 / 2 = 4.71

Answer:

x = 6

Step-by-step explanation:

using the Pythagorean theorem:

(4 + x)² = 8² + x²

16 + 8x + x² = 64 + x²

subtract x² and 16 from each side of the equation:

8x = 48

divide both sides by 8:

x = 6
