Answer:
y = -1
x = -1
Step-by-step explanation:
Area if the rectangle = 42 sq. inch
Area of a rectangle = l × b
42 = 12 × b
b = 42/12 = 3.5 inch
Now, perimeter of a rectangle= 2(l + b)
= 2(12+3.5) = 2(15.5) = 31 inches
Answer:
She had to sell 4 tickets
Step-by-step explanation:
Do 20 times 20%
20% OF 20
Answer:
x=-20
Step-by-step explanation:
1. Expand 3(x+8) : 3x+24
2.Expand -3(7-1/4x): -21*3/4x
3. 3x+24= -21*3/4x
4.<em>Subtract 24 from both sides</em>
3x+24-24= -21*3/4x-24
5.3x= 3/4x-45
6.<em>Subtract 3/4 from both sides</em>
3x-3/4= 3/4x-45-3/4
7.9/4x=-45
8<em>.Multiply both sides by 4</em>
9/4x*4=-45*4
9.9x=-180
10.<em>Divide both sides by 9</em>
9x/9=-180/9
11. x=-20

Hi there!
You need to prove that line segment DE ≅ GH.
You're given:
Line segment DJ ≅ line segment GJ;
E is the midpoint of line segment DF;
H is the midpoint of line segment GJ.
You can justify that line segment DE ≅ line segment GH with the midpoint definition, which is a point on a line segment that divides it into two equal parts. The two equal parts in this case are line segments DE and GH, so DE ≅ GH.
