Answer:
Multiply by 3 -> 3(x - y = 6)
Step-by-step explanation:
Cuz since the 2nd is positive 3y
u need a negative 3y to get rid of it
3(x - y = 6)
2x + 3y = 7
3x - 3y = 18
2x + 3y = 7
5x/5 = 25/5
x = 5
5 - y = 6
-5 -5
-y/-1= 1/-1
y = -1
(5,-1)
Answer:The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8

Answer:
The length of each of the other two sides would be 3.1 cm
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A. 3.1 cm
B. 3.2 cm
C. 4.2 cm
D. 6.1 cm
we know that
An isosceles triangle has two equal sides and two equal interior angles
Let
x -----> the length of each of the two equal sides in the isosceles triangle
The perimeter of one isosceles triangle is equal to

Remember that
To maximize the use of the wire, the perimeter of 6 earrings (3 pairs of earrings) must be equal to 50 cm
so

Solve for x




therefore
The length of each of the other two sides would be 3.1 cm
