Answer:
triangle =3
square= -2
star=7
circle=4
◇=18
right angled triangle= -5
Step-by-step explanation:
2triangle-1=5
+1 +1
2 triangles=6
1 triangle=3
3+ what is equal to one
the answer is -2
3-(2×-2)
3--4=7
second puzzle
3 circles =12
1 circle =4
◇+2=5 circles
◇+2=20
-2 -2
◇=18
2○=◇+ 2 right angle triangles
8= 18 + 2 right angled triangles
-10= 2 right angled triangles
-5= right angled triangle
Alright so 4 students rode in cars so do 490-4=486
Now do 486 (# of students riding bus) divided by 9 (how many buses) which gets u 54
So 54 students were on each bus
Answer:
x = 9
Step-by-step explanation:
<em>Theorem:</em>
<em>The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.</em>
The angle measuring 12x + 14 is an exterior angle of the triangle.
The angles measuring 76 deg and 1 + 5x are its remote interior angles.
12x + 14 = 1 + 5x + 76
12x + 14 = 5x + 77
7x = 63
x = 9
