Answer:
x=-2 y=3
Step-by-step explanation:
you should multiple second equation by -5 and collect all terms then put -2 from x
The <em><u>correct answer</u></em> is:
pairs 1 and 3
Explanation:
Congruent figures are the same size and the same shape.
Pair 1 has two polygons that are the same size and same shape; they are congruent.
Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.
Pair 3 has two polygons that are the same size and same shape; they are congruent.
Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.
We simplify the equation to the form, which is simple to understand
5(3+k)=45
Reorder the terms in parentheses
+(+15+5k)=45
Remove unnecessary parentheses
+15+5k=+45
We move all terms containing k to the left and all other terms to the right.
+5k=+45-15
We simplify left and right side of the equation.
+5k=+30
We divide both sides of the equation by 5 to get k.
k=6
