Peter is x years old and his sister is 5 years older. If the product of their ages is 84, form an equation in x and solve it to

daser333 [38]

Answer:

x^2 + 5x - 84 = 0

x = 7

Step-by-step explanation:

let the sister's age = y

sister's age (y) = 5 + x equation 1

xy = 84 equation 2

Make y the subject of the formula in equation 2

y = 84/x

equate equation 1 and 2

84/x = 5 + x equation 3

Multiply equation 3 by x

84 = 5x + x^2

x^2 + 5x - 84 = 0

tjis can be solved using quadratic equation

x^2 -7x + 12x -84 = 0

x(x + 12) -7(x + 12)

x = 7 or - 12

age cant be negative so his age is 7

Jenny buys 22 pens that cost $1.15 each and 15 markers that cost $2.05 each. How much did Jenny spend?

kykrilka [37]

You would do for pens

22 x 1.15 =25.30

And for markets

15 x 2.05 = 30.75

And since you are trying to find how much he spent in all you would add the two sums

25.30 + 30.75 = 56.05

PROBLEM SOLVING A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters. The shop says the length of

grin007 [14]

Answer:

$h > 189.66\ cm$ or $h< 129.31\ cm$

Step-by-step explanation:

Let

h ----> a skier's height in centimeters

we know that

A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters

The interval of the skis is -----> [150,220]

The compound inequality that represents the heights (in centimeters) of skiers the shop does not provide skis is

$1.16h > 220\ cm$ ----> inequality A

$1.16h< 150\ cm$ ----> inequality B

<em>Solve inequality A</em>

$1.16h > 220\ cm$

Divide by 1.16 both sides

$h > 189.66\ cm$

<em>Solve inequality B</em>

$1.16h< 150\ cm$

Divide by 1.16 both sides

$h< 129.31\ cm$

therefore

$h > 189.66\ cm$ or $h< 129.31\ cm$
