Answer:
x = 8.85
Step-by-step explanation:
20(x - 3) = 170 - 6x
20x - 60 = 170 - 6x
20x + 6x - 60 = 170
26x - 60 = 170
26x = 170 + 60
26x = 230
x = 230 / 26
x = 115 / 13
x = 8.84615 ≈ 8.85
Step-by-step explanation:
Scale factor red to blue meaning 42 to 7
42÷7=6
Scale factor is 6
Perimeter of the blue quadrilateral = ?
If perimeter of red = 204
Then we use this following proportion


Then we cross multiply
42x=7×204
42x=1428
x=34
Area of the blue quadrilateral = ?
If area of the red quadrilateral = 2880
Then we use the following proportion


Then we cross multiply
42x=2880×7
42x=20160
x=480
In pretty sure the answer would be 4/18. I think it would be this because If half the students are boys and 4/9 of the boys have brown eyes, this means that the whole club is 18. You add the two denominators. This equals the whole. Since it is asking for boys with brown eyes out of the whole group you put the number of brown eyed boys over the total number of kids.
Answer:
lol, u can still ask the question
Step-by-step explanation:
I hope this helps you
this triangle is isosceles right triangle
base=height
Area=base×height /2
18=b×b/2
b^2=36
b=6
