Answer:
x = b - y
Step-by-step explanation:
To get x by itself, subtract y from both sides.
y + x = b . . . . . . . . . given
y - y + x = b - y . . . . subtract y
x = b - y . . . . . . . . . simplify
Answer:
1/2 of a block
Step-by-step explanation:
Use proportions to solve
7.5 blocks / 15 minutes = x blocks / 1 minute
7.5=15x
x=.5
1. Multiply the numerators by the other's denominator( 7.5*1 will equal to 15*x)( * means times)
2. Isolate x by dividing 7.5=15x by 15 and you will have what x equals.
Answer:
20
Step-by-step explanation:
There are 6 ways to choose the first kitten, 5 ways the second, 4 ways the third
6*5*4
But order doesn't matter
Divide by the number of items factorial
3! = 3*2*1 = 6
6*5*4
--------

Answer:
Angle 1 = 22°
Angle 2 = 68°
Angle 3 = 68°
Angle 4 = 90°
Step-by-step explanation:
It is a rhombus by the definition:
A rhombus is a quadrilateral whose all four sides are equal in length and opposite sides are parallel to each other. However, the angles are not equal to 90°.
The properties of rhombus is:
(1) Opposite angles are equal
(2) All sides are equal and, opposite sides are parallel to each other
(3) Diagonals bisect each other perpendicularly
(4) Sum of any two adjacent angles is 180°
By property (3):
Angle 4 = 90°
By (1) and properties of isosceles triangle in the top right triangle:
Angle 2 = Angle 3 = 68°
In the top triangle:
Angle 1 + Angle 2 + 90° = 180° (Angle sum of triangle)
Angle 1 = 22°
Answer:
20
Step-by-step explanation:

So the answer is 20
