2 ( r - 1 ) + 3 = 19

Answer: B. 12 and 64

Step-by-step explanation:

Option A is incorrect because the highest common factor for both numbers would be 38 not 4.

Option B:

Factors of 12 are: 1, 2 , 3, 4, 6, 12

Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.

Highest factor of both is 4 and they both add up to 76 so option B must be correct.

Answer:

12 and 64 !

Step-by-step explanation:

Answer:

y = 68 degrees

Step-by-step explanation:

Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8

If one of the angles is y-8, then the rest are y-8 too

mathematically, by adding all , we have a total of 180

Thus;

3(y-8) = 180

y-8 = 180/3

y-8 = 60

y = 60+8

y = 68 degrees

Answer:

55°, 55° and 125°

Step-by-step explanation:

Opposite angles of a parallelogram are congruent, then

Angle opposite 125° is also 125°

Consecutive angles are supplementary, sum to 180°, then

consecutive to 125° is 55°

sngle opposite 55° is also 55°

The other 3 angles are 55°, 55° and 125°

Equality Properties

Step-by-step explanation:

Step 1: Define

13 + a/11 = 7

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that 7 does indeed equal 7.

∴ a = -66 is the solution to the equation.

Answer:

If you mean [tex]\frac{13+a}{7}=7[/tex] then the answer is [tex]a=36[/tex].

If you mean [tex]13+\frac{a}{7} =7[/tex] then the answer is [tex]a=-42[/tex].

Step-by-step explanation:

To do this question, you simplify both sides of the equation and then isolate the variable.

Answer:

d = 3√2

Step-by-step explanation:

find the constant of variation ('k'):  F = k/d²

16 = k/3²

16 = k/9

k = 144

8 = 144/d²

d² = 144/8

d² = 18

d = √9 · √2

d = 3√2

Answer:

  (6x+12)/x^2

Step-by-step explanation:

The product can be simplified by cancelling common factors from numerator and denominator.

  [tex]\dfrac{6x-18}{x^2}\times\dfrac{x^2+5x+6}{x^2-9}=\dfrac{6(x-3)}{x^2}\times\dfrac{(x+2)(x+3)}{(x-3)(x+3)}\\\\=\dfrac{6(x+2)}{x^2}=\boxed{\dfrac{6x+12}{x^2}}[/tex]

Answer:

C) 4.0 ft  

Step-by-step explanation:

We will use the Pythagorean theorem to solve this.  It states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse; algebraically,

a²+b² = c²

The height splits the base in two, giving us a leg of 3.  The hypotenuse is 5.  This gives us:

3²+b² = 5²

9+b² = 25

Subtract 9 from each side:

9+b²-9 = 25-9

b² = 16

Take the square root of each side:

√b² = √16 = 4

Answer:

-11, -10, -9, -8, -7, -6 and -5

Step-by-step explanation:

Given the inequality expressions

2x+9<0  and x>-12

2x+9<0

2x< 0-9

2x < -9

x < -9/2

x < -4.5

Since x >-12

-12 < x

Combining both inequalities

-12 <x  < 4.5

The integers between the intervals are -11, -10, -9, -8, -7, -6 and -5

Answer:

161 seniors

Step-by-step explanation:

According to the problem, given data are as follows:

Total number of sophomores = 300

Sophomores to junior ratio = 5:4

So, Number of Juniors = 300 ×  (4 ÷ 5)

= 240

Now, Juniors to senior ratio = 3:2

So, we can calculate the number of seniors by using following method:

Number of seniors = 240 × ( 2 ÷ 3)

= 240 × 0.67

= 160.8 or 161

Answer:

30 sweets

Step-by-step explanation:

From the above question

The ratio is given as:

Karan : Preeti

2:3

The sum of the proportion = 2 + 3 = 5

Total number of sweets = 50 sweets

The number of sweets Preeti will get is calculated as:

3/5 × 50 sweets

= 30 Sweets

Therefore, the number of sweets Preeti will get is 30 sweets

Answer:

128π - 8

Step-by-step explanation:

Hypotenuse length:

4² + 4² = 32

2π(√32/2)²  = (√32)² × 2² = 2π × 32 × 4 = 2π × 128

256π is the area of the circle

Area of shaded region = area of circle/2 - area of triangle

256π/2 = 128π

128π - 16/2

128π - 8 = area of shaded region

Answer:

The answer is B. $3.85.

Step-by-step explanation:

This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.

Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.

This is why the answer is B. $3.85.

Answer:

3 weeks

65 dollars

Step-by-step explanation:

Alright to answer this question we have to set up an equation. For greg the equation is y=13x+26 and for lucy the equation is y=10x+35. y is total amount of money saved and x is number of weeks. Since we want them to each of the same amount of money we set up the equations to be 10x+35=13x+26

then we want to get the constant and the variables alone on different sides of the equal sign so we first subtract 26 from each side to get 10x+9=13x. next we want to subtract 10x from each side and then we end up with 3x=9. Finally we divide 3 from each side to get x=3, We have answered the question to how many week it will take them to save the same amount of money but not the other part. To find out how much money they will both have in 3 weeks we plug in 3 to x. 10(3)+35 which is equal to 65. They will both have 65 dollars in three weeks

Answer: hi want to be fwends

Step-by-step explanation:

There can 3 songs to be played for per quarter.

A unit conversion expresses the same property as a different unit of measurement.

Given that, It cost Sean 3.75 to play 45 songs on an old jukebox. The jukebox only accepts quarters.

Converting $3.75 into quarters,  ($1 = 4 quarters)

$3.75 = 3+0.75

= 3x4+0.75

= 12+3

= 15 quarters

So, he played 45 songs in 15 quarters

Therefore, in 1 quarters = 45/15

= 3

Hence, There can 3 songs to be played for per quarter.
