Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation:
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation:
Solving both equations simultaneously we can find value of x and y
Let:
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
So, value of x=9
Now finding value of y by putting value of x in equation 1
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
There are 7 ways for it to be and odd sum. Can you figure out the even sums?
Given:
Three different integer addition expressions equal −5.
To find:
The three different integer addition expressions.
Solution:
We know that 0 is the identity element under addition. It means if we add 0 to a number we get the same number.
One expression is .
The other expression are:
Therefore, the three different integer addition expressions that are equal to -5 are .
