Answer:
Step-by-step explanation:
-5x+31+3x=3
move everthing to one side
-5+31+3x-3=0
add and subtract common terms
-2x+28=0
divide across by common denominator
-x+14=0
Solve for x
x=14
Answer:
<u>1073333/5000000</u>
Step-by-step explanation:
To convert from decimal to fraction : take denominator as 10000000.
2146666/10000000
<u>1073333/5000000</u>
X (a + 2) = 7
First let's multiply out the brackets on the left side of the equation.
x (a + 2) --> Multiply everything inside the brackets by x.
xa + 2x = 7
Now, both elements of the left-hand side of the equation contain x, so we can divide both sides of the equation by x.
xa + 2x = 7
a + 2 = 7/x
To find a now, just subtract 2 from both sides.
a = 7/x - 2
In a parallelogram sum of the adjacent angles
equals supplementary.
opposite angles are equal.
Let the smaller angle = x°
larger angle = twice the smaller angle - 30°
=2x° - 30°
x° +2 x° - 30 = 180°
3x° = 180 + 30
3x = 210
x = 210 / 3
x = 70°
Therefore,
smaller angle = x = 70°
larger angle = 2x - 30
= 2 × 70 - 30
= 140 - 30
= 110°
Required parallelogram angles are 70° , 110° ,
70° , 110°
I hope this helps you.
