snow_tiger [21]3 years ago
8 0

Answer:

x² + 2x - 15 = 0

x² + 2x + 1 = 16

(x + 1)² = 16

You can then go forward with that to solve it:

x + 1 = √16

x = -1 ± √16

x = -1 ± 4

x = 3, -5

Mother dairy sold 3,355 litres of milk in the month of April and May if they sold equal amount every day what was its daily sale
Shkiper50 [21]

Answer:

<h2>55 litres </h2>

Step-by-step explanation:

Litres of milk sold by the dairy in April and May together = 3,355

So,

Litres of milk sold by the dairy per day = ?

To find this we have to do addition and division and have to go through the calender a bit :)

<h2>Let's solve it!!</h2>

No. of days in April = 30 days

No. of days in May = 31 days

Therefore total no. of days in both the months = 30 + 31

= 61

Now,

Litres of milk sold by the dairy per day ( or in simple words the daily sale )

=  \frac{3355}{61}

= 55

Si therefore 55 litres of milk was the daily sale.

Hope it helps you!!

Measure of a verticle angle is 7x+182 and another angle is 9x+194 solve for x
disa [49]
The measures of 2 vertical angles are always equal, so we have:

7x+182=9x+192.

Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x. 

Thus, x=-6.


This means that the angles are:

i) 7x+182=7(-6)+182=182-42= 140(degrees).

ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)


Answer: x=-6</span>

7<br> Solve for x.<br> x + 1<br> 12<br> 15<br> X =
dangina [55]
X=4. First, you do 15/12 and get 1.25. You do this to see what number you have to multiply 12 to, to get 15. Since the sides a proportional it should be the same for the sides with their variables. Then you create an expression that puts the numbers the same place where 15 and 12 were to equal 1.25. You cross multiply, solve and get 4.
