Zoe thinks of a number. She multiplies it by 3 and adds 4. She gets the same answer when she adds 5 to the number and then multi

Fiesta28 [93]

Answer:

Zoe's number is 6

Step-by-step explanation:

Let the number be 'n'

a) Multiply 'n' by 3 ⇒ n*3 = 3n

Add 4 to '3n' ⇒ 3n + 4

Add 5 to 'n' ⇒ n +5

Multiply (n+ 5) by 2 ⇒ (n +5)*2 = 2n + 5*2 = 2n + 10

3n + 4 = 2n + 10

b) 3n + 4 = 2n + 10

Subtract 4 form both sides

3n = 2n + 10 - 4

3n = 2n + 6

Subtract 2n from both sides

3n - 2n = 6

$\sf \boxed{\bf n = 6}$

Vinvika [58]

Answer:

P22039

Step-by-step explanation:

Cost of new television = 29078

Let the price of old model television = x

2x - 15000 = 29078

2x = 29078 + 15000

2x = 44078

2x/2 = 44078 /2

x = 22039

Hence, price of old model television is P22039

lawyer [7]

Answer:

3 1/3 km or 3.33 km (to the hundredth)

Step-by-step explanation:

Using the given formula,

estimated distance = v.t = velocity * time,

velocity = 5 km/h

time = 40 minutes = $\frac{40}{60}$ hours = $\frac{2}{3}$ hours

Therefore

distance = 5 km/h * $\frac{2}{3}$ hours = 10/3 km

= 3.33 km approximately
