Answer:
x = -14
Step-by-step explanation:
3 + x/2 = -4
Subtract 3 from both sides:
x/2 = -7
Multiply both sides by 2:
x = -14
The size of the angle QUP in the system formed by the <em>equilateral</em> triangle QUR, the <em>equilateral</em> triangle PUT and the square RUTS is equal to 150°.
<h3>How to determine a missing angle within a geometrical system</h3>
By Euclidean geometry we know that squares are quadrilaterals with four sides of <em>equal</em> length and four <em>right</em> angles and triangles are <em>equilateral</em> when its three sides have <em>equal</em> length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.
Finally, we must solve the following equation for the angle QUP:
<em>m∠QUR + m∠QUP + m∠PUT + m∠RUT =</em> 360
60 <em>+ m∠QUP +</em> 60 <em>+</em> 90 <em>= 360</em>
<em>m∠QUP +</em> 210 <em>=</em> 360
<em>m∠QUP =</em> 150
The size of the angle QUP in the system formed by the <em>equilateral</em> triangle QUR, the <em>equilateral</em> triangle PUT and the square RUTS is equal to 150°.

Answer:
x=0
Step-by-step explanation:
30x=60-60
Or,30x=0
or,x=0/30
or,x=0

8 sodas X $1.59 =$12.72 per week
$12.72 per week X 4 weeks per month =$50.88
$50.88 X 12 months per year = $610.56 per year
