Answer:
y=4
Step-by-step explanation:
4y + 3 =19
4y = 16
y= 4
The answer is B
a1= 13;an-1+2
<u>Answer</u>:
x = 3
<u>Step-by-step explanation</u>:
9x = 27
Divide both sides by 9,
x = 27/9 which on factorization of the numerator is written as
x = 9 x 3/9 = 3
Calculation 2: Exponent Or Index Method
9x = 27
Since 9 = 3² and 27 = 3³, the given equation takes the form
3² x = 3³
This gives
x = 3³ ÷ 3² = 3³¯² [using the formula a^m ÷ a^n = a^(m-n)]
= 3¹ = 3 (since the first power of a number is the number itself)
9 x 1 = 9
9 x 2 = 16
<h2>
9 x 3 = 27</h2>
9 x 4 = 36
We stop here because we have already got the answer 27, the right-side of the equality, when 9 is multiplied by 3 . So,
x = 3
hope this helped!
6*4=24. Just keep on grinding them out to learn them! Good Job!
