♧ So, after 3 years = x+81 +3

♧ now grouping the variables and constants together we get,

♧ Thus, Victor's present age is 24 yrs.

Hope it helps ya ~

Answer:

Victor's age = 24 years old

Step-by-step explanation:

Let age of Mr. Smith = x and age of Victor = y.

According to the question, we can find two equations.

=> 1) x = y + 81

=> 2) x + 3 = 4(y + 3)

Substituting value of x in (1) to (2)

y + 81 + 3 = 4y + 12

3y = 72

y = 24

Victor's age = 24 years old

Answer:

8y

Step-by-step explanation:

=(6)(2x)+(6)(y)+2y+−12x

=12x+6y+2y+−12x

Combine Like Terms:

=12x+6y+2y+−12x

=(12x+−12x)+(6y+2y)

=8y

Answer:

8y

Step-by-step explanation:

6(2x+y) comes first 12x+6y then you take 2y and add it from 6y giving you 8y and that gives you the most simplified answer 12x and -12x cancel each other out

Answer:

6in

Step-by-step explanation:

Let's organize what we know.

- 5gal/1in

- 30gal tank

Since we need to find the inches of the fish he can have, we can set up a proportion like this:

5/1=30/x

We can cross multiply.

5x=1(30)

Simplify: 1*30=30

5x=30

Now we can isolate the variable.

[tex]9.0*10^{-10}[/tex]

Step-by-step explanation:

Scientific notation is a way of expressing numbers that are too large or too small.

To figure out the power of 10, think "how many places do I move the decimal point?"

1. When the number is 10 or greater, the decimal point has to move to the left, and the power of 10 is positive.

2. When the number is smaller than 1, the decimal point has to move to the right, so the power of 10 is negative.

Answer:

6.4

Step-by-step explanation:

divide 4 by 30 in order to find out how many miles she can run in a minute. I got 0.13333333 and multiplied that by 48, which got me 6.4 as the answer but I'd double check.

Answer:

6.4 millas.

Step-by-step explanation:

es una simple regla de tres:

4 es a 30

x es a 48

x es igual a 48*4/30

x es igual a 6.4

Answer:

D)

Step-by-step explanation:

4 is an evident zero of the equation x^3 - 64.

x^3 - 64 can only be factorized with (x-4) and not with (x+4)

because x - 4 = 0 <==> x = 4 and 4^3 -64 = 0

Developing B) would be:

x^3 + 4x^3 + 16x - 4x^2 - 16x - 64 = 5x^3 - 4x^2 -64

So it doesn't match so it's D)

Since both angles will be a part of triangle, and the third angle would be 90° as, the vertices meet at an centre of diagonal, hence they bisect each other.

7x-12 +(10x+5) = 90°

==> 17x -7= 90°

==> 17x = 97°

==> x = 97°/17

==> x = 5.70° (approx)

Answer:

Step-by-step explanation:

Answer:

The answer is A)

Step-by-step explanation:

To find out table contains a set of points that lie in the graph of this function , we have to hit and trial method ,

when we put the value of x in y = –2x + 3 this equation so ,

taking x = 1 , then the value of y is

=> y = -2(1)+3

=> y = -2+3

=> y = 1

taking x = 0 , then the value of y is

=> y = -2(0)+3

=> y = 3

now talking x = -3 , then the value of y is

=> y = -2(-3) +3

=> y = 6+3

=> y = 9

so , the option A is the right answer

Answer:

A)

Step-by-step explanation:

Given linear function:  y = -2x + 3

Therefore, the slope is -2 and the y-intercept is (0, 3)

Therefore, we are looking for a set of ordered pairs that has a rate of change of -2

⇒ as the x-value increases by 1 unit, the y-value decreases by 2 units

i.e. as the x-value decreases by 1 unit, the y-value increases by 2 units.

The only set of ordered pairs that follows this rule is A)

Let's check by substituting the values of x = 1, x = 0 and x = -3 into the function:

when x = 1 → -2(1) + 3 = 1

when x = 0 → -2(0) + 3 = 3

when x = -3 → -2(-3) + 3 = 9

Confirming that the set of ordered pairs in A) lie on the graph of the given function.

The amount more in interest over the life of the loan which Nellie have to pay is $14814.

Bankruptcy is the procedure by which the people who are unable to pay the debts to creditors, may get relief from some or all the debts.

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans.

Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. Thus, the interest is,

[tex]I=\dfrac{45000\times6\times15}{100}\\I=40500[/tex]

If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. In this case, the interest paid would be,

[tex]I=\dfrac{45000\times6\times6}{100}\\I=16200[/tex]

The difference between the interest paid would be,

[tex]I=40500-16200\\I=24300[/tex]

Hence, the amount more in interest over the life of the loan which Nellie have to pay is $14814.

Answer:

Yes, he is correct, 240 miles will require a gas volume of 13.71 gallons which is less than 15 gallons in  Enrique's car.

Step-by-step explanation:

Given;

total volume of gas in Enrique's car, V = 15 gallons

The rate of gas consumption [tex]= \frac{35 \ miles}{2 \ gallons} = 17.5 \ miles/gallon[/tex]

To drive 240 miles, he would need the following volume of gas;

[tex]V = 240 \ miles* \frac{1}{\frac{17.5 \ miles}{gallon} }\\\\ V = 240 \ miles*\frac{1*gallon}{17.5 \ miles}\\\\ V = (\frac{240 \ miles}{17.5 \ miles} )gallon\\\\V = 13.71 \ gallons[/tex]

The volume of gas needed to drive 240 miles is less than the total volume of gas in Enrique's car.

Thus, he is correct

Answer:

$486 (Paul)

$243(Brian)

$81(Colin)

Solving steps:

let Paul Be x, Brian be x,Colin be x

since Paul got twice as much as Brian which shows that brian and got three times

So Paul,= 3×2 so he got six times as much as the two others

while Brian got three times

and colins got once

so let's make an equation for this problem

=> 6x + 3x + x = $810

add 6 x + 3 x + x which give you 10 x

=> 10x = $810

divide both side by the coefficient of x

=> [tex] \frac{10x}{10} = \frac{810}{10} [/tex]

=> [tex]x = \frac{810}{10} [/tex]

=> x = 81

since you we have find what the value of x

insert into the previous equation which is

=> 6x + 3x + x

=> 6(81) = $486-----(for Paul)

3(81) = $243-------(for Brian)

(81) = $81 ---------(for Collin)

Answer:

There is no values of c that makes it true

Step-by-step explanation:

The roots of the quadratic equation x² – 2x + c = 0 are 0 and –2. Then the value of c is zero.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

For which values of c does the quadratic equation

x² – 2x + c = 0 ...1

The one root is equal to zero and one negative root.

Let negative a be the one root.

x = 0, –a

Then we have factorized the equation,

(x)(x + a) = 0

On solving, we have

x² + ax = 0 ...2

In comparing equation 2 with equation 1, we have

a = –2 and c = 0

Answer:

Step-by-step explanation:

On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.

After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.

Therefore we can write the following equation:  (Where d = number of days)

B = 10 + 8d

W = 0 + 9d = 9d

We are told that eventually they will sell the same amount which means

B = W

This means we can say,

10 + 8d = 9d

If we subtract 8d from both sides we get

10 = d

Therefore it will take 10 days for them to sell the same amount of cookie dough.

Answer: 10 days

10 + 8 x 10 = 90

9 x 10 = 90.

It will take 10 days for Ben and Winston to sell the same amount of cookie dough.

The equation of the line plotted in the graph with the similar triangles on the coordinate plane is y equal to three-fourths x.

Symbolically, it can be written as,

[tex]y=\dfrac{3}{4}x[/tex]

The equation of the line is the way of representation of a line in the equation form.

The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.

[tex]y=mx+c[/tex]

Here, (m) is the slope of the line and (c) is the y intercept.

The similar triangles on the coordinate plane to determine the equation for the given line. The line and the triangle is graphed in the image attached below.

The line passes from origin point (0,0). The coordinate points on the line say P are (4,3) as shown in the image. Thus, for this the slope of the line can be given as,
