Answer:
2 positive * 1 negative = negative
2 negative * 1 positive = positive
Step-by-step explanation:
one positive and 2 negative
(+ * -) * - =
positive times negative = negative * negative = positive
(+ * -) * - = +
now if we change the order by putting parenthesis
+ *( - * -)
negative time negative = positive
+ * (+) = positive
the result is positive
The result does not change because of where we put the parentheses.
- * + * + =
negative times positive = negative
negative * positive= negative
- * + * + = negative
The order does not matter
Let x= cucumber plants
5x= tomato plants
6x+7= pepper plants
peppers = 19
therefore
6x+7=19
subtract 7 from both sides
6x= 12
divide both sides by 6
x=2
replace the x with 2
2= cucumber plants
10= tomato plants
hope this helps
