Giselle is 24 years younger than her mother. In six years time she will be 1/4 of the age of her mother.

Mathematics

Let the age of Giselle = x

Age of mother = x+24

After 6 years,

Age of Giselle = x + 6

Age of mother = x+24+6

= x + 30

4(x + 6) = x + 30 \\ 4x + 24 = x + 30 \\ 4x = x  + 30 - 24 \\ 4x = x + 6 \\ 4x - x = 6 \\ 3x = 6 \\ x =  \frac{6}{3}  \\  \\ x = 2

<h2><u>Age of Giselle now = 2</u></h2>

... Hope this will help....

(x + y + 2)(y + 1)<br> Solve

Hello there! We are given the following equation and want to simplify it:

(x+y+2)(y+1)

First, let's use the Distributive Property:

  • (a+b)(c)=ac+bc

For this step, we are going to let:

  • a=y
  • b=1
  • c=(x+y+2)

After applying this version of the Distributive Property, we are given the equation:

(y)(x+y+2)+(1)(x+y+2)

We're going to use the distributive party again, but a slightly different version that's almost the same as first:

  • (a)(b+c+d)=ab+ac+ad

Using this on both terms of the equation changes the equation to:

(xy+y^2+2y)+(x+y+2)

Now, we just remove the parenthesis and combine like terms

y^2+3y+xy+x+2

This should be your answer. Let me know if you need any clarifications, thanks!

If a polyhedron has 5 faces and 7 vertices, then it must have how many edges? Please show step-by-step work
Juli2301 [7.4K]

Answer:

10 edges

Step-by-step explanation:

we know that

The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

V - E + F = 2

in this problem  we have

V=7\\E=?\\F=5

substitute the given values

7 - E + 5 = 2

solve for E

Combine like terms in the left side

12 - E = 2

subtract 12 both sides

- E = -10

Multiply by -1 both sides

E =10

In 2010, the population of Kingsford was 8000. By 2014 the population had increased by 15% and 2/5 of the population was age 12
Anastasy [175]
<h2>Hello!</h2>

The answer is: The population age 12 or under was 3680.

<h2>Why?</h2>

If in 2010 the population of Kignsford was 8000, and by 2014 the population had increased by 15% we need to calculate the total population and then, calculate how many people was age 12 or under.

We must remember that we cannot work with percentage values, so, to make 15% a real number, we need to divide it by 100:

15(Percentage)=\frac{15}{100}=0.15

So,

Calculating the population by 2014, we have:

Population_{2014}=Population_{2010}+ Population_{2010}*0.15

Then, substituting we have:

Population_{2014}=8000+ 8000*0.15=9200

Now, calculating the population that was age 12 or under, knowing that it was 2/5 of the total population, we have:

Population=TotalPopulation*\frac{2}{5}\\\\Population=9200*\frac{2}{5}=3680

So, the population age 12 or under was 3680.

Have a nice day!
