<h3>to understand this</h3><h3>you need to know:</h3>- linear equation
- linear equation word problems
- PEMDAS
- linear equation:y=mx+b
all we need to care about the middle condition which is
<h3>the new test score is 15 points more than the original score</h3>given that
original score is x
New score is y
if you pay attention to the given condition
we can find it same as linear equation
therefore
according to the question
the equation is
<h2>y=x+15</h2>Answer:
17
Step-by-step explanation:
Since angle KLJ~angle VWU are similar :
KL / WV = KJ/ UV
(25 / 20) = (4x - 23 / 2x + 2)
Cross multiply :
25(2x + 2) = 20(4x - 23)
50x + 50 = 80x - 460
50x - 80x = - 460 - 50
-30x = -510
x = 510 / 30
x = 17
