Solve for x:

Sonja [21]

$\frac{2x}{5} + 1 = \frac{1}{15}$

---------------------------------------------------------
Take away 1 from both sides
---------------------------------------------------------
$\frac{2x}{5} = \frac{1}{15} - 1$

---------------------------------------------------------
Evaluate the value on the right
---------------------------------------------------------
$\frac{2x}{5} = - \frac{14}{15}$

----------------------------------------------------------
Multiply by 15 on both side
---------------------------------------------------------
$\frac{2x}{5} \times 15 = - \frac{14}{15} \times 15$

---------------------------------------------------------
Evaluate
---------------------------------------------------------
$6x = -14$

---------------------------------------------------------
Divide by 6 on both sides
---------------------------------------------------------
$x = - \frac{14}{6}$

---------------------------------------------------------
Simplify
---------------------------------------------------------
$x = - \frac{7}{3}$

$Answer \: x = - \frac{14}{6} \ or - \frac{7}{3}$

You can answer only this question, it's ok:

Sophie [7]

1)100 or A
Angle = |30*H - (11/2)*M|, where H is the hours hand and M is the minutes hand

in this case: H = 4, M= 40
30*4 - (11/2)*40 = 120 - 220 = -100 = |-100| = 100
2)x=4y or C
If you plug in 0,0 you will get 0=4×0 or 0,0

Find m<1 A: 69 B: 71 C: 86 D: 111

Studentka2010 [4]

The correct answer is: [A]: "69° " .
______________________________________________________
m∠1 = 69° .
______________________________________________________
Explanation:
_____________________________________________________

180 - (39 + 30) = 180 - 69 = 111. This is the measurement of the third angle in the triangle. Note that all angles in a triangle add up to 180° . All triangles have 3 (three) sides and 3 (three) angles.

To find m∠1 :
_____________________________________________________
The only single angle that exists that is supplementary to ∠1 is 69.

So: m∠1 = 180 - 111 = 69 . (Note: since all angles on a straight line are supplementary angles; and supplementary angles add up to 180° .
_______________________________________________________
The answer is: 69° .

m∠1 = 69° .

Substitution. 3x + 2y = 12 y = 2x – 1

Korvikt [17]

Answer:x=2 and y=3

Step-by-step explanation:

Given that y=2x-1

Then, 3x+2y=12

3x+2(2x-1)=12

3x+4x-2=12

7x=14

x=2

y=2(2)-1

y=3
