What is 9-x/5=3?<br> I kept getting 6 but the only option is -6 :/

borishaifa [10]

Step-by-step explanation:

$9 - \frac{x}{5} = 3 \\ 9 - 5 \times \frac{x}{5} = 3 \times 5 \\ 9 - x = 15 \\ - 9 - x = - 9 + 15 \\ - x = 6 \\ - x \div - 1 = 6 \div - 1 \\ x = - 6$

What is the factorization of the trinomial below -x^2 + 2x + 48

OlgaM077 [116]

For this case we must factor the following expression:

$-x ^ 2 + 2x + 48$

We take the sign "-" as a common factor of the expression, taking into account that:

$- * - = +\\- (x ^ 2-2x-48)$

To factor, we must find two numbers that, when multiplied, result in -48 and when added, result in -2. These numbers are -8 and +6.

$-8 + 6 = -2\\(-8) * (+ 6) = - 48$

Then, we factor the expression within the parenthesis as:

$- ((x-8) (x + 6))$

Answer:

$- (x-8) (x + 6)$

Step-by-step explanation:

reasons

1:sum of all side of triangle is 180 degree(here is 220)

3: try in copy and u will able to solve

4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.

5: 3y+5y+y=180

9y=180

hence,y=20

Triangle TIC is an isosceles triangle with a vertex angle I. If the measure of Angle I = 90degrees, then find the measure of ang

Katena32 [7]

It's B. An isosceles triangle has two angles that are the same because they are across from 2 sides that are the same. Therefore, these 2 angles must have the same measure. Because of the triangle angle-sum theorem, all the angles add up to 180. So 180-90 = 90 and 90/2 = 45
