Answer:
x = 2
x = 17
Step-by-step explanation:
Triangle ADC can be similar to AEB by property of similar angles (vertices are corresponding)
AC/AB = AD/AE
(10 + x)/10 = 18/15
15(10 +x) = 180
15x + 150 = 180
15x = 30
x = 2
Or
AD/AB = AC/AE
18/10 = (10+x) / 15
10(10+x) = 270
10x + 100 = 270
10x = 170
x = 17
Answer:
Area of circle=πr^2
Step-by-step explanation:
Area of circle=πr^2
=22/7*21^2
=22/7*441
=9702/7
=1386 sq.inch
Answer: 662.50 dollars
==========================================================
Explanation:
If she doesn't sell a single thing, she still earns the base weekly salary of $310. This is the smallest amount she can earn per week.
If she does make sales, then she'll earn an additional 0.075x dollars where x is the amount of sales made (the total value of the merchandise). The 0.075 is the decimal form of 7.5%
In total, she makes 0.075x+310 dollars per week. In this case, she sold x = 4700 dollars worth of goods, which means,
0.075x+310 = 0.075*4700+310 = 662.50
She earned 662.50 dollars for that week.
Answer:
Look at the explanation.
Step-by-step explanation:
Start y=-2x-3 at the Y -3 and X 0, then go up two and to the right one, like a staircase. For y=-x+3 start on Y 3 and X 0 and go down 1 x and 1 y like a downstair staircase with 1 unit down.
I'll leave the picture to you; draw a rectangle and write 2x+4 along the length and 4x along the width. We don't really know the aspect ratio of the rectangle until we know x so any rectangle is fine.
The perimeter is the sum of all four side lengths,
p = (2x + 4) + 4x + (2x + 4) + 4x
Answer: p = 12x + 8
