$-\frac{1}{2} = y -1\\y=0.5$

$-3\pi + w = 2\pi\\w= 5\pi$

$1.2m = 0.6\\m = 0.5$

$q + 2.7 + -0.9 = q + 1.8$

Answer:

Option D: 3x2 + 2x - 1

Step-by-step explanation:

Given that:

=(5x2 - 5x + 3 )- (2x2 +7x- 4)

As we have to subtract them so by simplifying:

"-" sign will alter all signs in the bracket

= 5x2 - 5x + 3 - 2x2 + 7x - 4

Now by adding same terms

= 5x2 - 2x2 - 5x + 7x + 3 -4

= 3x2 + 2x - 1

i hope it will help you!

Answer:

Solution is invalid

Step-by-step explanation:

Let the time when they will have the same water content be x hours

At x hours;

For the first tank, the content will be;

50 + 10x

For the second;

29 + 3x

Equating both, will give us x

29 + 3x = 50 + 10x

We will get x as a negative number here

Since number of hours can not be negative, the solution is invalid

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value of $y = 122^o$

The value of $x = 61^o$

Step-by-step explanation:

Generally the total angle that make up a circle is

$\theta _T = 360$

From the diagram we see that

$\theta _T = y^o + 238^o$

=> $y^o = 360 -238$

$y^o = 122^o$

Generally angle that is formed as a result of interception of a chord and a tangent is equal to the intercepted arc divided by 2

This implies that

$x = \frac{y}{2}$

substituting values

$x = \frac{122}{2}$

$x = 61^o$
