The answer is B

-2x-27/9 = x+4

Multiply both sides by 9 & then simplify

-2x+26=9x+36

Move all terms not containing (x) to the left side

-11x+27=36

-11x=9

Divide each term by 11

X= -9/11

Answer:

<u>The correct answer is B. {-9/11}</u>

Step-by-step explanation:

1. Let's solve the linear equation:

x-6/-3 + x+9/9 = x+4

-3(x - 6) + x + 9 = 9 (x + 4) (Multiplying by 9 at both sides)

-3x + 18 + x + 9 = 9x + 36

-3x + x - 9x = 36 - 18 - 9 (Like terms)

-12x + x = 36 - 27

-11x = 9

<u>x = -9/11</u>

2. Let's prove that x = -9/11 is correct

x-6/-3 + x+9/9 = x+4

(-9/11 - 6)/-3 + (-9/11 + 9)/9 = -9/11 + 4

(-75/11 * - 1/3) + (90/11 * 1/9) = -9/11 + 44/11

25/11 + 10/11 = 35/11

<u>35/11 = 35/11</u>

<u>We proved that x = -9/11 is correct.</u>

Determine the quadrant when the terminal side of the angle lies according to the following conditions: cos(t)&gt;0, tan(t)&gt;0
Oksi-84 [34.3K]
Cos(angle) look at the 'x' axis, so cos(t)>0, means positive x, or quadrants I and IV.

tan(angle)  = sin(angle)/cos(angle),  so it's a division. sin(angle) has the sign of the y axis.

So, tan(t)>0, mus be +/+ or -/-,  quadrant I or III, respectively.

The only in common is quadrant I. Hope it helps for the next one!

On a test, a student got 80% of the items correct. If the student got 56 items correct, how many items were on the test?
posledela
80% of what is 56
0.80x = 56
x = 56/0.80
x = 70

check..
80% of 70 is 56
.80(70) = 56
56 = 56 (correct)

so there were 70 items on the test
