Answer:
x = 14.25
Step-by-step explanation:
Start with a^2 + b^2 = c^2
a = 11
b = x
c = 18
plug in and solve
11^2 + x^2 = 18^2
121 + x^2 = 324 - Simplify
x^2 = 203 - subtract 121 from both sides
x = 14.247 rounds to 14.25 - square root on both sides

Answer:
just Move the 6
7p−3r−5s+6
Step-by-step explanation:
Gaira made a mistake when substituting the value –7.5 in for x.
She multiplied both terms of the expression by –7.5 when she should have only multiplied –3.8 by –7.5.
The value of the expression is 34.5.
Given
Gaira was asked to evaluate the algebraic;
–3.8x + 6 when x = –7.5.
<h3>What is an algebraic expression?</h3>
Algebraic expressions consist of numbers and variables along with operational signs.
Gaira made a mistake when substituting the value –7.5 in for x.

I think I have 2 options for you and I hope they can work good for you:
The first one:
<span>($1.50 times x)/y = z
</span>Or the second one could be:
<span>Z = (X x 1.50) / Y
</span>Please prove which of the two are ok for you. I hope this helps
