Answer:

-35

Step-by-step explanation:

Using the rules of BIMDAS, division goes before addition, hence -20/2 which gives you -10

Put that in the equation and it would be:

-10 + (-15)

A negative and a positive make a negative hence, you could simply write it as:

-10 - 15

Which equals -35

Eddi Din [679]

Answer:

600 words

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (100, 2.5, 5) as shown below:

$\frac{100}{2.5}=\frac{x}{15}$

Next we cross multiply. We multiply 2.5 and x, and we multiply 100 and 15.

$2.5(x)=2.5x$

$100(15)=1,500$

Now, lets put the values above back into the equation:

$2.5x=1,500$

Our next step is to divide 1,500 by 2.5 to get <em>x</em> by itself.

$x=\frac{1,500}{2.5}$

$x=600$

Sylvia can type 600 words in 15 minutes.

It is because u can only do pathagreom therom on right triangles.

square root of 8.41 is 2.9 so that confrms the therom which isaversa confirms it is a right triangle.

3k2-19=15k-1 solve by factoring

kow [346]

For this case we must factor the following expression:

$3k ^ 2-19 = 15k-1$

We manipulate algebraically, taking into account that different signs are subtracted and the sign of the major is placed:

$3k ^ 2-15k-19 + 1 = 0\\3k ^ 2-15k-18 = 0$

We divide by 3 on both sides of the equation:

$k ^ 2-5k-6 = 0$

To factor, we look for two numbers that, when multiplied, result in -6 and when added, result in -5. These numbers are -6 and +1.

$-6 + 1 = -5\\-6 * (+ 1) = - 6$

Thus, we factor the equation:

$(k-6) (k + 1) = 0$

The roots of the equation are:

$k_ {1} = 6\\k_ {2} = - 1$

ANswer:

$k_ {1} = 6\\k_ {2} = - 1$
