Answer:
Step-by-step explanation:
a). Let the number of spoons = x
And number of forks = y
Total number of spoons and forks bought by Perry = 10
x + y = 10 --------(1)
Cost of one spoon = $5
Cost of one fork = $3
Therefore, total cost of x spoons and y forks = $(5x + 3y)
5x + 3y = 42 -------(2)
b). Now we can convert these equations into the slope-intercept form.
x + y = 10 ⇒ y = -x + 10
Table for input output values,
x 2 4 6
y 8 6 4
5x + 3y = 42
3y = -5x + 42
y =
x 0 3 6
y 14 9 4
Point of intersection of these lines will be (6, 4).
Solution of 8 x 4 - 4 divided by 2 +1 is 9.33
<h3><u>Solution:</u></h3>Given that,
8 x 4 - 4 divided by 2 +1
We have to compute the above equation
Let us write the given sentence mathematically:
Let us BODMAS rule to solve the above expression
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.
So let us first perform multiplication of 8 and 4 in numerator
Now we can perform addition of 2 and 1 in denominator
Now we can perform subtraction of 4 from 32 in numerator
Now perform division of 28 by 3
Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
