Answer:
Step-by-step explanation:
Let's solve for x.
−3x−4y=5
Step 1: Add 4y to both sides.
−3x−4y+4y=5+4y
−3x=4y+5
Step 2: Divide both sides by -3.
−3x

The least number of points Jared needs to score is 53.
Jared already has an average of 86%. He want to have an overall average of 88. His exam is worth 20% of the total grade. This information can be modelled as:
(0.8 x 86%) + (0.2 x a) = 88%
a = score in the exam.
68.8 + 0.2a = 88%
Combine similar terms
0.2a = 88 - 68.8
0.2a = 19.2
a = 19.2 / 0.2
a = 96%
Jared has to score 96% on the exam.
The second step is to determine which score would give 96%
x / 55 = 96%
x = 55 x 0.96
x = 52.8
x = 53

Rewrite as
![\frac{2 x^{2} }{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20x%5E%7B2%7D%20%7D%7B3%7D%20)
= 24
Multiply both sides by 3 to isolate 2x².
2x² = 72
Divide both sides by 2 to isolate x².
x² = 36
Square root both sides to isolate x.
x = -6 or 6
-6 is smaller than 6.
The smallest solution is -6.
This is the concept of numbers, given that the radicals sqrt2 and sqrt3, what we can deduce from the two radicals is that they are both like terms. This is because, they don't make perfect squares now that there are no integers such that x*x=sqrt 2 or x*x=sqrt3.
They are also not equal to each other because, 2 ≠ 3
