Answer:

v = 3 , 3/5

Step-by-step explanation:

5 {v}^{2}  - 18v + 9 = 0 \\ 5 {v}^{2}  - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v =  \frac{3}{5}

6x+18y=18 find y and z
Masja [62]

6x + 18y = 18. Let us take x = 0

6(0) + 18y = 18

0 + 18y = 18

18y = 18

y = 18/18

y = 1

(0, 1) [x = 0, y = 1]

6x + 18y = 18. Let us take y = 0

6x + 18(0) = 18

6x + 0 = 18

6x = 18

x = 18/6

x = 3

(3, 0) [x = 3, y =0]

Infinite solutions can be found for x and y

The depth of a lake in cedar burg changes over time due to rain fall and evaporation this year it was 39 feet which is 25% less
Nostrana [21]

Answer:

The depth of the lake last year was 52 feet

Step-by-step explanation:

Given as :

This year depth of lake = 39 feet

Let the last year depth of lake = x feet

Now,

According to question :

The depth this year is 25% less than that of last year

I.e 39 feet = x - 25% of x

Or, 39 feet = \frac{75x}{100}

or, x =  \frac{3900}{75}

∴   x = 52 feet

Hence The depth of the lake last year was 52 feet   Answer
