Answer:
Step-by-step explanation:
prob blue = 3/12 = 1/4
since you are replacing ,
prob(blue, blue) = (1/4)(1/4) = 1/16
Answer:
$5.10
Step-by-step explanation:
15% of 34
15/100 × 34 = $5.10
Answer:
a≥0
Step-by-step explanation:
The equation on the left is absolute value so all values plugged in will be positive but on the other side if a negative was plugged in it would still be negative and thus result in a lower sum than the other side. For example:
|-2+5|=-2+5
7=3
this is untrue.
the equation would only be true if the a values were positive.
Answer:
6
Step-by-step explanation:
The figure inside the circle is symmetric. Therefore, 3x + 5 = 5x - 7. Solving for x, we subtract 3x from both sides and then add 7 to both sides. This comes out to 2x = 12, meaning that x must be 6.
Answer:
Step-by-step explanation:
In an isosceles triangle, two sides and two angles are equal.
The shortest side of an isosceles triangle is 2x+5 inches. The 2 longest sides are 3 inches longer. This means that the length of each of the longer sides is
2x + 5 + 3 = 2x + 8 inches
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
Where a, b and c are the sides of the triangle.
The perimeter of the triangle is 21 inches. Therefore, the equation that can be used to find the length of each side of the triangle is
2x + 5 + 2x + 8 + 2x + 8 = 21
6x + 21 = 21
