X-5y=33<br> 5x-6y=70<br> solve the system by the addition method

BARSIC [14]

For this case we have the following system of equations:

$x-5y = 33\\5x-6y = 70$

We multiply the first equation by -5:

$-5x + 25y = -165$

Thus, we have the equivalent system:

$-5x + 25y = -165\\5x-6y = 70$

We add the equations:

$-5x + 5x + 25y-6y = -165 + 70\\19y = -95\\y = - \frac {95} {19}\\y = -5$

We find the value of the variable "x":

$x-5 (-5) = 33\\x + 25 = 33\\x = 33-25\\x = 8$

Thus, the solution of the system is:

$(x, y) :( 8, -5)$

Answer:

$(x, y) :( 8, -5)$

Aliyah created the circle graph to show the weather for April in her hometown. How many of the 30 days in April were rainy?

Stells [14]

10 Days in April will be Rainy Days

Step-by-step explanation:

Percentage formula will be used to calculate the number of days which will be rainy

Given

Percentage of rainy days = 33%

Total days in April = 30

So 33% of 30 days of April will be rainy

Now

$No.\ of\ Rainy\ Days = 33\%\ of\ 30\\=0.33*30\\=9.9$

Rounding off to nearest whole number

9.9 => 10

Hence,

10 Days in April will be Rainy Days
