Rocco spent 20% of his savings on clothes. He brought $50 clothes. How much did he have in the beginning
Anna71 [15]
Howdy,

20% is also 1/5 in fraction form, which tells us he spent 1/5 of his money on clothes:

So to solve, we have to multiply 50 by 5:

50 x 5 = 250

Rocco's original savings was $250

Hope this helps! <span />

Find y<br>Solve the simultaneous <br>equations<br><br><br>3x + 2y = 27 3x - Y = 9<br>​
lutik1710 [3]

Answer:

y = 6

Step-by-step explanation:

To find y, we need to eliminate x in this system of equations:

3\cdot x + 2\cdot y = 27 (1)

3\cdot x - y = 9 (2)

From (1) and (2):

x = \frac{27-2\cdot y}{3}

x = \frac{9+y}{3}

Then, we equalize both expressions and solve for y:

\frac{27-2\cdot y}{3} = \frac{9+y}{3}

27-2\cdot y = 9 + y

3\cdot y = 18

y = 6
