Answer:
1 dollar is equal to 0.75 E
Step-by-step explanation:
120$ = 90 e -----> 4$ = 3E
250$ = 187.50 e -----> 4$ = 3E
400$ = 300 e -----> 4$ = 3E
----------------------------------
from this we know 4$ = 3E
1 E = 4$/3
1 E = 1.33...$
---------------------
1 $ = 3/4 E
1 $ = 0.75 E
---------------------
1.33...$ dollars is equal to 1 E and
1 $ is equal to 0.75 E
-----------------------------------
90 x 1.33... =120
187.50x1.33...= 250
300 x 1.33... = 400
--------------------------
To solve this question, what you would need to do is add 30 to both sides of the equation and then divide by 9, to find the solution.
You can check if it is correct by substituting the same value back into the original equation and seeing if the left hand side is equal to the right hand side.

Equivalent representations of percent problems
Step-by-step explanation:
For the answer to the question above asking to p<span>rove the Pythagorean Theorem using similar triangles. The Pythagorean Theorem states that in a right triangle,
</span>A right triangle consists of two sides called the legs and one side called the hypotenuse (c²) . The hypotenuse (c²)<span> is the longest side and is opposite the right angle.
</span>⇒ α² + β² = c²
<span>
"</span>In any right triangle ( 90° angle) <span>, the sum of the squared lengths of the two legs is equal to the squared length of the hypotenuse."
</span>
For example: Find the length of the hypotenuse of a right triangle if the lengths of the other two sides are 3 inches and 4 inches.
c2 = a2+ b2
c2 = 32+ 42
c2 = 9+16
c2 = 15
c = sqrt25
c=5
