Answer:
Step-by-step explanation:
<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>You might be interested in
Given:
Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.
To find:
The percentage increase of amount of pears picked by Kim.
Solution:
We know that,
Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.
For this equation, you want to do it in fractions/ratios to properly solve it. You would have his average misses out of every field goal and his real missed attempts over total. It would look like this
= 
You want to solve for x since x is the total amount of field goals that he attempted. You can do this by doing cross multiplication:
(2)(x) = (8)(11)
From here you can get:
2x = 88
Divide each side by 2 to isolate x and you get:
x= 44
So he made a total of 44 field goals.
