Answer:

x= 11

y=14

z=17

Step-by-step explanation:

(Last number - first number in series) / numbers from the first to last number in series

8 + 3 = x

x + 3 = y

y + 3 = z

Can someone help me with this? Ava uses 8⁄9 gallonsof water every time she waters her lemon tree. If she waters her lemon tree 1

Nataly_w [17]

If Ava waters her lemon tree 12 times, then she has used 10.667 gallons of water.

<u>Solution:</u>

Given that , Ava uses $\frac{8}{9}$ gallons of water every time she waters her lemon tree.

If she waters her lemon tree 12 times, we have to find how much water will she use

Total water used = water used for 1 time $\times$ number of time water used for plants

Here water used for one time = $\frac{8}{9} gallons$

Number of time watered = 12

$\text { Total water used }=\frac{8}{9} \text { gallons } \times 12 \text { times }$

$\text { Total water used }=\frac{8}{9} \times 12=\frac{8}{3} \times 4=\frac{32}{3}=10.667$

Hence, Ava used 10.667 gallons of water.

Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km t

german

Answer:

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time taken by Dina to cover 10 km}=\frac{10km}{5\frac{km}{hr}}$

$\text{Time taken by Dina to cover 10 km}=\frac{10km}{5}\times \frac{hr}{km}}$

$\text{Time taken by Dina to cover 10 km}=2hr$

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

$\text{Distance covered by Masha}=10\text{ km}-2\text{ km}=8\text{ km}$

Now let us find Masha's biking speed.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Masha's biking speed}=\frac{8\text{ km}}{2\text{ hour}}$

$\text{Masha's biking speed}=4\frac{\text{ km}}{\text{ hour}}$

Therefore, Masha's biking speed is 4 km per hour.
