The value of x is √2.5
<h3>How to solve arithmetic?</h3>
Arithmetic can be solved by using PEMDAS rule.
P = parenthesis
E = exponential
M = Multiplication
D = division
A = addition
S = Subtraction
Therefore,
12 - 4 + 5x² = 20
12 - 4 + 5x² = 20
8 + 5x² = 20
5x² = 20 - 8
5x² = 12
x² = 12 / 5
x = √2.4

Answer:3.08e
Step-by-step explanation:mujwjwieekedkd
Part A.
Consider a punch containing L liters.
60% of these that is

is grape juice, and the rest, 0.4 L is lemon-soda.
so, for the variable L, the total amount of punch, the total amount of grape juice is 0.6 L
and the amount of lemon soda in the punch is 0.4L
Part B.
For L=2, we substitute and get:
0.6 L=0.6 * 2 liters = 1.2 liters of grape juice
0.4 L = 0.4 * 2 liters = 0.8 liters of lemon soda.
