Answer: v = -13

Step-by-step explanation:

Multiply both sides of the equation by (v+12). On the right side, the (v+12) terms will cancel leaving only (v+4). On the left, we will have 9(v+12). Therefore:

[tex]9(v+12)=v+4[/tex]

Distribute the 9 into the parenthesis to get:

[tex]9v+108=v+4[/tex]

Subtract 'v' on both sides to get:

[tex]8v+108=4[/tex]

Subtract 108 from both sides to get:

[tex]8v=-104[/tex]

Divide both sides by 8 to get:

[tex]v=-13[/tex]

Answer:

-40

Step-by-step explanation:

The equation that can be used to represent the ages of Sarah and his brother will be 2x - 12 = 16.

From the question given, Sarah's brother is 12 less than twice her age and Sarah is 16.

Let Sarah's age be represented by x.

Therefore, the equation to represent the situation will be:

= (2 × x) - 12 = 16

2x - 12 = 16

2x = 16 + 12.

2x = 28

x = 28/2 = 14

Sarah is 14 years.

Answer:

The lattes would cost about 22.50

Step-by-step explanation:

In order to figure out how much 6 lattes cost we need to know how much 1 is.

So you take 15 divided by 4 which gets you 3.75

Then you take 3.75 and times it by 6. Getting you the answer of 22.50

Answer:

$22.5

Step-by-step explanation:

It would be 22.5$ because if lattes cost 15$ then we need to find the cost of 1.

To do this by we divide 15 by 4.

     3.75

4{15}

 -0

___

  15

- 12

--------

    3 so because there is 3 left of 4 is is .75 because it couldn't make it to 4

so since 1 latte cost 3.75$ we times 3.75 by 6 latte.

Here are 3.75 times numbers 1-6.

3.75 x 3=11.25

3.75 x 4=15

3.75 x 5=18.75

3.75 x 6=22.5 and there's your answer,you get 6 lattes for 22.5$ or 22$ and 50 cents.

x<30

Step-by-step explanation:

-2x-4> -64

add 4 to both sides

-2x-4+4> -64+4

simplify the arithmetic

-2x> -64+4

-2x>-60

divide both side by -2

When dividing or multiplying by a negative number, always flip the inequality sign

-2x/-2 <-60/-2

Cancel out the negatives:

2x/2<-60/-2

Simplify the fraction:

x<-60/-2

Cancel out the negatives:

x<60/2

Find the greatest common factor of the numerator and denominator:

x<30 . 2 / 1 . 2

Factor out and cancel the greatest common factor:

solution,

5x-6y+z+5x-6y-z

(+z and -z will be cancelled)

now,

5x+5x-6y-6y

10x+ 12y( because 2 minus makes plus)

The slope of a line that is perpendicular to y = x - 6 means that the slope has to be a negative reciprocal of the original slope

That means the slope of the line that is perpendicular to y = x - 6 is '-1'

B. Clockwise 270-degree rotation

Answer:

B) Clockwise 270-degree rotation

Step-by-step explanation:

Clockwise motion is in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite motion is counterclockwise.

From inspection of the diagram, we can see that the curved dotted line (which shows the direction of motion) is suggesting a clockwise motion.

Surface area of square pyramid is given by the sum of areas of all its 4 triangular sides and the square base area. If a is the base side length and l is the slant height , then the surface area of square pyramid is:

‎ㅤ‎‎ㅤ‎ㅤ‎ㅤ‎ㅤ➙ a² + 2al

Ⲧⲏⲉⲅⲉ⳨ⲟⲅⲉ:

‎ㅤ‎ㅤ‎ㅤ➙ A = a² + 2al

‎ㅤ‎ㅤ‎ㅤ➙ A = ( 3 ) ² + 2 × 3 × 5

‎ㅤ‎ㅤ‎ㅤ➙ A = 9 + 30

‎ㅤ‎ㅤ‎ㅤ➙ A = 39m²

~Hence, the surface area of given square pyramid is 39 m².

Answer:

39 m²

Step-by-step explanation:

surface area of square based pyramid = [tex]a^2+2al[/tex]

(where [tex]a[/tex] is the side length of the base and [tex]l[/tex] is the slant height)

Given:

⇒ SA = 3² + (2 x 3 x 5) = 39 m²        

V = π r² h

r = 3/2 = 1.5m

h = 3m

taking π as 3.14

V = π r² h

= 3.14 × 1.5 ×1.5 × 3

= 21.195 m³
