You could do 21-5 and get the answer 16
A= 16+5 = 21
So therefor, he is 16 years old now.
One way to illustrate the binomial<span> distribution is with a histogram. A histogram shows the possible values of a probability distribution as a series of vertical bars.</span>
P = 2( l + w)
Length: 2y
Width: y - 4
P= 22 inches
2(2y) + 2(y - 4) = 22
4y + 2y - 8 = 22
4y + 2y = 6y and add (-8) on both sides of the equation to equal: 6y = 30
Divide 6 from both sides of the equation and you get: y = 5
Check:
4(5) + 2(5) - 8 = 22
20 + 10 - 8 = 22
30 - 8 = 22 ✅
Answer:
a. 3x = 45
15cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle = 45cm .
Using the equation
3x = 45
Divide both sides by 3
x = 45/3
= 15cm
The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal
