Answer: x = 10 and y = 3

Step-by-step explanation:

Due to the x rule, (5x - 17) = (3x + 3)

If we add 17 to both sides:

5x = 3x + 20

Take away 3x from both sides

2x = 20

Divide by 2:

X = 10

This means that (5x - 17) = (3x + 3) = 33

Since all angles must add to 360, the top angle = (360- (33*2)) /2

(360-66) /2

294 /2

147

This shows that 9x - 19y = 147

90 - 19y = 147

Minus 90 both sides

19y = 57

Y = 3

So, x = 10 and y = 3

How do I work this out

alukav5142 [94]

Answer:

no, it is good for 2 weeks (almost 3)

Step-by-step explanation:

The volume of the pool is ...

V = LWH

V = (20 m)(8 m)(1.8 m) = 288 m³

Then the amount of chlorine powder needed for 1 week is ...

(300 g/(50 m³)) × (288 m³) = 1728 g

A box of 5000 g holds enough chlorine for ...

(5000 g)/(1728 g/treatment) = 2.89 treatments

A box of chlorine powder is enough for 2 weeks, not 4.

In another aquarium display, there are 40 fish in each of 7 large tanks. How many fish are in the display?

expeople1 [14]

In this particular question, you just need to multiply the number of tanks with the number of fish each tanks able to contain.

So, 7 x 40 = 280 fishes

the tortoise can walk 1/2 mile in 1/4 of an hour. The hare can run 11/2 mile in half an hour. What is the distance

Shalnov [3]

Answer:

The speed of tortoise is 2 miles per hour and

The speed of hare is 11 miles per hour

Step-by-step explanation:

Given as :

The distance cover by tortoise = $\frac{1}{2}$ miles

The Time taken by tortoise to cover distance = $\frac{1}{4}$ hour

So, The speed of the tortoise is = $\dfrac{\textrm Disatnce cover by tortoise}{\textrm time taken}$

I.e The speed of the tortoise = $\frac{\frac{1}{2}}{\frac{1}{4}}$

∴ The speed of the tortoise = 2 miles per hour

Again ,

The distance cover by hare = $\frac{11}{2}$ miles

The Time taken by hare to cover distance = $\frac{1}{2}$ hour

So, The speed of the hare = $\dfrac{\textrm Disatnce cover by hare}{\textrm time taken}$

I.e The speed of the hare = $\frac{\frac{11}{2}}{\frac{1}{2}}$

∴ The speed of the hare = 11 miles per hour

Hence The speed of tortoise is 2 miles per hour and

The speed of hare is 11 miles per hour . Answer
