The meaning of the x-value when y=90 means that Anthony will use 3.1 hours.
<h3>What is an equation?</h3>
An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
The relationship that can be represented by the equation y=57+7.4x,
where
y represents the expected quiz score
x represents hours spent on homework that week.
When y = 90, the value of x will be:
y=57+7.4x
57 + 7.4x = 90
Collect like terms
7.4x = 90 - 57
7.4x = 23
Divide
x = 23/7.4
x = 3.1
He'll use 3.1 hours.

Ok so to simplify 32^3/5, you will need to know the steps, so I'll tell u the step by step solution. ;D
So Step 1: You have to <span>Raise 32 to the 3rd power:
</span><span><span>1.1 </span> 32 = 2</span>⁵
(32)³ = (2⁵)³ = 2¹⁵
<span>the equation has ended on step 1, so now is:
</span><span> 2</span>¹⁵
<span>------
5
</span>
Now step 2:
Simplify it
(you can't simplify this equation but these is the steps you gotta do on other equations so I'm just giving an example.)
2¹⁵
------
5
So basically your final result is:
2¹⁵
------
5

Hope you understand it :D

Answer:
the answer is C, 369
Step-by-step explanation:
1. divide 800 by 40 which will give you 20
2. then multiply 18 by 20
3. answer is 360
the reason I did this was because if you had multiplied math, physics and chemistry by 20 it would have given you the total of 800 trials
