Answer:

28 years

Step-by-step explanation:

youngest brother's age = x

middle brother's age = x+2

oldest brother's age = x+4

3(x-2) = (x+2)+48

[simplify]

3x-6 = x+50

[add 6 to each side]

3x = x+56

[subtract x from each side]

2x = 56

[divide each side by 2]

x = 28

Answer:

13

Step-by-step explanation:

I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now

The system of the equation is :

[tex]2x=y\\3y-4x=10[/tex]

Thus, the age of the ava's turtle is 5 years.

Given:

Ava's turtle is half as old as her parrot.

The turtle will be 3/4 as old as her parrot in 10 years.

Let us assume the age of the turtle is x years and the age of the parrot is y years.

According to the first statement, the variables can be related as:

[tex]{x}=\dfrac{y}{2}\\2x=y[/tex]

According to the second statement, the variables can be related as:

[tex]\begin{aligned}x+10&=\dfrac{3}{4}(y+10)\\4(x+10)&=3(y+10)\\4x+40&=3y+30\\4x-3y&=-10\\3y-4x&=10\end{aligned}[/tex]

Thus, the system of the equation is :

[tex]2x=y\\3y-4x=10[/tex]

By solving the above system of the equation, we get x=5 and y=10.

Thus, the age of the ava's turtle is 5 years.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Proportion of males, P(M) = 77% = 0.77

Proportion of females = ( 1 - proportion of males) = (1 - 0.77) = 0.23

Percentage of males who smoke cigar = 11.3% = 0.113

Percentage of female who smoke cigar = 2.1% = 0.021

Expressing cigar smoking Data as conditional probability :

P(male and smoking) = P(M n C) = 0.113

P(Female and smoking) = P(F n C) = 0.021

Probability of smoking cigar Given the person is a male :

P(C | M) = P(M n C) / P(M)

Probability of smoking cigar Given person is a female :

P(C | F) = P(F n C) / P(F)

Find the probability that the selected subject does not smoke cigars given that the subject is male?

No smoking Given Male = 1 - P(C | M)

P(C | M) = P(M n C) / P(M)

P(C | M) = 0.113 / 0.77

P(C | M) = 0.1467

1 - P(C | M)

1 - 0.1467

= 0.8533

Answer:

If the numerator of a fraction is greater than or equal to its denominator, then the fraction is an improper fractio. That is the fraction a/b is called improper if a ≥ b.

Example : 1/1,  2/1,  5/1,  4/3,  6/4,  9/5,  7/7, ...etc

Answer:

Step-by-step explanation:

Solving the equation

Multiplying both sides by 7 to clear fractions

Answer:

x = -14/9

Step-by-step explanation:

1/7 + 3/7(3x - 5) = -4

~Subtract 1/7 to both sides

3/7(3x - 5) = -29/7

~Multiply 7 to both sides

3(3x - 5) = -29

~Simplify left side

9x - 15 = -29

~Add 15 to both sides

9x = -14

~Divide 9 to both sides

x = -14/9

Answer:

The equation in the slope-intercept form is

y = -5x - 41

Step-by-step explanation:

The given equation in the question is;

y = -5x + 2

The equation of a straight line graph can be written in the form;

y = mx + c

where m is the slope and c is the intercept

From here, we can see that the slope m is -5

Since the line is parallel to the new line we are trying to write its equation, it means that they have the same value of intercept.

Hence, the slope of the new line is also -5

Now, we can write the equation of the new line as;

y = -5x + c

we need to get the value of c here however

To get the value of c, we need to input the value of x and y

From the graph, x = -7 and y = -6

Substituting these values, we have;

-6 = -5(-7) + c

-6 = 35 + c

c = -6 -35

c = -41

So the equation of the new line will be;

y = -5x - 41

Answer:

Square Root of 48 to the nearest tenth, means to calculate the square root of 48 where the answer should only have one number after the decimal point. To check that the answer is correct, use your calculator to confirm that 6.92 is about 48.

Step-by-step explanation:

There ya gooooo :)

The value of the expression √48 will be given as 6.93.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ √48

The power of the number 48 is 1/2. Then the value of the expression will be

[tex]\rightarrow \left ( 48 \right )^{\frac{1}{2}}\\[/tex]

→ 6.93

The value of the expression √48 will be given as 6.93.

Answer:

Part A:

m∠VHT = 152°

Part B:

m∠QTS = 152°

Part C:

m∠ZHQ = 28°.

Step-by-step explanation:

Part A:

The given parameters are;

m∠HXU = 113°

Segment BQ and segment UD intersect at m∠XAT = 95°

We have that m∠HXU + m∠HXS = 180° (Angles on a straight line)

Therefore;

m∠HXU  = 180° - m∠HXS = 180° - 113° = 67°

m∠HXU = 67°

m∠XAT + m∠XAH = 180° (Angles on a straight line)

m∠XAH  = 180° - m∠XAT = 180° - 95° = 85°

m∠XAH = 85°

In triangle XAH, we have;

m∠XAH + m∠HXU + m∠XHA = 180° (Angle sum property of a triangle)

∴ m∠XHA = 180° - (m∠XAH + m∠HXU) = 180° - (85° + 67°) = 28°

m∠XHA = 28°

m∠VHT + m∠XHA = 180° (Angles on a straight line)

m∠VHT  = 180° - m∠XHA = 180° - 28° = 152°

m∠VHT = 152°

Part B:

m∠QTS ≅ m∠VHT (Corresponding angles are congruent)

∴ m∠QTS = 152° (Substitution property)

Part C:

m∠ZHQ ≅ m∠XHA  (Reflexive property)

∴ m∠ZHQ = 28°.

Answer: y= - 4x+18

Step-by-step explanation:

Equation: y=mx+b

***remember: b is the y-intercept and m is the slope.

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

3= x1

2= x2

6= y1

10=y2

m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4

m=-4

Now we have y=-4x+b , so let's find b.

You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:

   (3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.

   (2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.

Equation of the line: y=-4x+18

Answer:

The answer would be A. It is the population PER YEAR, so it would not be C or D because the population change is only negative, and -2,500,000 people/year is way too much. It must be A, -83,333 people/year. Hope I helped!
