Answer:

x = 11

Step-by-step explanation:

From the diagram, we find,

(2x - 16) + (x - 8) = 9

=> 2x - 16 + x - 8 = 9

=> 2x + x - 16 - 8 = 9

=> 3x - 24 = 9

=> 3x = 9 + 24

=> 3x = 33

=> x = 33/3

=> x = 11

Mandisa draws a rectangle to represent the area of her yard. The area can be represented by 10x2 – 13x – 14.

andrew-mc [135]

Answer:

(x-2) and (10x+7)

Step-by-step explanation:

10x²-13x-14

10x²-20x+7x-14

10x(x-2)+7(x-2)

(x-2)(10x+7)

the factors are (x-2)(10x+7)

meaning that the length and breadth are (x-2) and (10x+7)

Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate

vladimir2022 [97]

Answer: 250 m

Step-by-step explanation:

Given

Distance between Ursula and Velda house is 4 km or 4000 m

Ursula walks at the rate of $400\ m/h\ or\ \frac{20}{3}\ m/min$

Velda walks at the rate of $600\ m/h\ or\ 10\ m/min$

Time taken by them to cover 4000 m is

$\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min$

Distance covered by them 15 min before they meet

Ursula $=\frac{20}{3}\times 225=1500\ m$

Velda $=10\times 225=2250\ m$

The total length covered by them is $=1500+2250=3750\ m$

They are $4000-3750=250\ m$ apart before they meet

If gasoline costs 1.50 euros per liter it will cost how much to drive 220 kilometers

jok3333 [9.3K]

Answer:

$11.79\ euros$

Step-by-step explanation:

<u><em>The complete question is</em></u>

Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?

step 1

using proportion

Find out the number of liters of gasoline needed for 220 kilometers

$\frac{28}{1}\ \frac{Km}{L}=\frac{220}{x}\ \frac{Km}{L}\\\\x=220/28\\\\x=7.86\ L$

step 2

Find the cost to drive 220 kilometers

Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km

$1.50(7.86)=11.79\ euros$
