If there is 1000 seats, and the students took 45% percent of them, then 450 sixth graders went on the trip
The number of white sweatshirts is 28
Step-by-step explanation:
Let ordered black shirts be represented by b
Let ordered white shirts be represented by w
So total sweatshirts will be represented by the equation
b+w=50
The total cost of the ordered sweatshirts will be represented by
10b + 12 w= $556
For simultaneous equations as;
b+w=50
10b+12w=556
solving the equations using substitution method where b=50-w
10(50-w)+12w=556
500-10w+12w=556
-10w+12w=556-500
2w=56
w=56/2= 28
b=50-w=50-28=24

Answer:
<h2>x = 60°, y = 50°</h2>
Step-by-step explanation:
We know: the angles measures in a triangle add up to 180°.
<em>(look at the picture)</em>
z + 50 + 60 = 180
z + 110 = 180 <em>subtract 110 from both sides</em>
z = 70°
x + 50 + 70 = 180
x + 120 = 180 <em>subtract 120 from both sides</em>
x = 60°
Angles x, y and z are on one side of a straight line. Therefore they add to 180°.
x + y + z = 180
60 + y + 70 = 180
y + 130 = 180 <em>subtract 130 from both sides</em>
y = 50°
We would find it by multiplying:
(x -6) * (x +3) * (x -5) =
x^3 -8x^2 -3x +90
2 out of 6 (3 out of 6 if 3 itself is included)
