A quilt is designed using a square pattern. Each square contains two rectangles. Each rectangle contains a shaded rhombus.
2 answers:
The sum of angles in any Rhombus is 360 degrees.Opposite angles of a rhombus are congruent.
Two of the adjacent angles are 2x+20 and 50 degrees.
The opposite angles measure 2x+20 and 50 degrees.
Sum of angles in any Rectangle is 360
2x+20+50+2x+20+50=360
Adding line terms,
4x+140=360
Subtracting 140 both sides:
4x=220
Dividing both sides by 4
x=55
Option B. 55 is the right answer.
The 4 angles of a rhombus should add up to be 360 degrees.
So,........................... 2x + 20 + 2x + 20 + 50 +50 = 360
Combine like terms:............................... 4x + 140 = 360
Subtract 140 from both sides ..........................4x = 220
Divide by 4.............................................................. x = 55

Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
Answer:
y = 4x + 12
Step-by-step explanation:
The slope of the line y = 4x - 9 is 4.
The slope of the line we are looking for is also 4.
y - y1 = m(x - x1)
y - 4 = 4[x - (-2)]
y - 4 = 4(x + 2)
y - 4 = 4x + 8
y = 4x + 12
Answer: y = 4x + 12
It is 10 times bigger. It is easy because you can do 50 x 10 which is 500 and you know it is 10 times bigger.
