Answer:

James is 37, Rob is 44, and Kate is 35

Step-by-step explanation:

Set up an equation where x is James' age:

Rob's age can be represented by x + 7, since he is 7 years older than James

Kate's age can be represented by x - 2, since she is 2 years younger than James

Add these together in the equation and set it equal to 116:

(x + 7) + (x - 2) + (x) = 116

Add like terms and solve for x:

(x + 7) + (x - 2) + (x) = 116

3x + 5 = 116

3x = 111

x = 37

So, James is 37.

Find Rob's age by adding 7 to this:

37 + 7

= 44

Find Kate's age by subtracting 2:

37 - 2

= 35

So, James is 37, Rob is 44, and Kate is 35

<h3>Solution:</h3>

$\frac{1}{x} = \frac{x + 3}{ {2x}^{2} } \\ = > \frac{2 {x}^{2} }{x} = x + 3 \\ = > 2x = x + 3 \\ = > 2x - x = 3 \\ = > x = 3$

<h3>Answer:</h3>

The answer is option d. X = 3

Please help this is due tomorrow :,)

Given

in ∆ABC

AB = 5cm

BC = 6 cm

AC = 7 cm

now,

as we have to make ∆PQR inside it

than, possibly ∆PQR's sides length is,

PQ = ½ of CB (according to mid point theorem)

→ CB = 6cm → 6/2 → 3cm

PQ = 3cm

QR = ½ of AC

→ AC/2 = 7/2 = 3.5 cm

RP = ½ of AB

→ AB/2 = 5/2 = 2.5cm

therefore, length of

PQ = 3cm

QR = 3.5 cm

PR = 2.5 cm

Hope this answer helps you dear!

What is the value of 3^3 - (4^2 - 2^3)?

Illusion [34]

3³ - (4² - 2³)

3³ = 3x3x3 = 27

4² = 4x4 = 16

2³ = 2x2x2 = 8

3³ - (4² - 2³) = 27 - (16 - 8) = 27 - 16 + 8 = 19 (answer C)
