Let the number be x.
Therefore, by the problem
x/6-(-3) = 12
or, x/6+3 = 12
or, x/6 = 12-3
or, x/6 = 9
or, x = 9 × 6
or, x = 54
The number is 54.
The solution of your problem is shown on the picture below.
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees

1. Answer=66cards
Lets use the variable 'x' to represent the number of baseball cards in Keith's collection that he started with. The following equation can be made.
(x+6)/2=36
multiply both sides by 2
x+6=72
subtract 6 from both sides
x=66 cards
2. Answer=$12
Lets use the variable 'a' to represent Sara's allowance. The following equation can be made:
(a/2)+7=13
subtract 7 from both sides
a/2=6
multiply both sides by 2
a=$12
