Hey there,
7 / 10 + 1 / 6
1st Step : Make the denominators the same (30)
7 / 10 (multiply by 3) = 21 / 30
1 / 6 (Multiply by 5) = 5 / 30
Step 2: Add them together.
21 / 30 + 5 / 30 = 26 / 30
Hope this helps ^_^

First, find the area of the circle A=pi r^2 = 3.14 (8)^2=200.96
the radius is half the diameter so r=16/2=8
Second, find the area of the triangle A=(hb)/2=(8*16)/2=64
since the triangle is resting on the diameter of the circle that means the height of the triangle is also the radius of the circle so h=8 and b=16
Third, subtract the area of the triangle from the area of the circle to find the area of the shaded regions.
so...
200.96-64=136.96
is the answer.
Answer:

Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455

x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills

OK.
Answer:
x squared over 16 minus y squared over 25 equals 1
Step-by-step explanation:
x²/4² - y²/5² = 1
x²/16 - y²/25 = 1
