Step-by-step explanation:
1. An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. ... An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Answer:
No becasue she only has 22 yard and the total she needs is more than 23 yards
Let's say each row has x desks and there are y rows.
We then know that x*y =25
We also know that x*2-5=y (number number of rows is five less than twice the number of desks in each row)
So we substitute: x*(x*2-5)=25
putting numbers out of the brackets:
2x*x-5x=25
2x*x-5x-25=0
(2x+5)(x-5)=0 (this bracketing is true: you can check it by expanding it:
2x*x-10x+5x-25
So that means that either x=-2.5which can't be : there can't be a fractional number of benches,
or x=5
so each row has 5 desks and there are 2*5-5 rows, or 5 rows.
she should have invested P, in order to get I = 6500
but she instead invested 17,801, how much more did she need? well, P - 17801
solve for P
