Let
x ----> kilograms of strawberries that Sheldon picks in the morning
y ---> kilograms of strawberries that Sheldon picks in the afternoon
so
we have that
x=y-1 2/5
x=2 1/4 kg
substitute
2 1/4=y-1 2/5
Convert mixed numbers to an improper fraction
1 2/5=1+2/5=7/5
2 1/4=2+1/4=9/4
substitute
9/4=y-7/5
y=(9/4)+(7/5)
y=(45+28)/20
y=73/20 kg
Adds kilograms in the morning and afternoon
x+y=(9/4)+73/20)
x+y=(45/20)+(73/20)
x+y=118/20 kg
Convert to mixed number
118/20=100/20+18/20=5+18/20=5+9/10=5 9/10 kg
therefore
<h2>The answer is 5 9/10 kg</h2>
Answer:
Go through the explanation you should be able to solve them
Step-by-step explanation:
How do you know a difference of two square;
Let's consider the example below;
x^2 - 9 = ( x+ 3)( x-3); this is a difference of two square because 9 is a perfect square.
Let's consider another example,
2x^2 - 18
If we divide through by 2 we have:
2x^2/2 -18 /2 = x^2 - 9 ; which is a perfect square as shown above
Let's take another example;
x^6 - 64
The above expression is the same as;
(x^3)^2 -( 8)^2= (x^3 + 8) (x^3 -8); this is a difference of 2 square.
Let's take another example
a^5 - y^6 ; a^5 - (y ^3)^2
We cannot simplify a^5 as we did for y^6; hence the expression is not a perfect square
Lastly let's consider
a^4 - b^4 we can simplify it as (a^2)^2 - (b^2)^2 ; which is a perfect square because it evaluates to
(a^2 + b^2) ( a^2 - b^2)
Step-by-step explanation:
you know the answerv noow
X^2+kx-35
=x^2+kx+-35
=kx+x^2-35
Suppose the students who scored 85 and 90 on the math test take the test again and score 95. How many stars would you have to add to the picturegraph next to 95?
