Hopefully I’m not too late, but here’s how I solved it. Basically, replace F with 68. Subtract 32 from both sides so your equation becomes 9/5C=36. Divide both sides by 9/5 so C is left but itself (C=36/1.8). The answer should come out to 20. If you want to check my answer, plug 20 into the equation. Multiply 20x9/5 which equals 36. Add 36 and 32 together to get 68. Hope this helps
Answer: (0, -6)
Explanation:
6x - 6 = -4x - 6
10x = 0
x = 0
y = 6(0) - 6
y = 0 - 6
y = -6
Answer: x is 45, y is 80
Step-by-step explanation:
subtract the angles surrounding x (70 - 25 = 45)
add 45 + 55 to get 100
the entire triangle has to equal 180 degrees, so subtract 100 from 180 to get the value of y
Answer:
11) 2 x 3.14 x (19/2) > (we want to use the radius)
2 x 3.14 x 9.5 = 59.66
12) 2 x 3.14 x (11/2) > (we want to use the radius)
2 x 3.14 x 5.5 = 34.54
34.54/2 + 11 = 28.27 >(becuase it is only a semicircle)
the plus 11 is the diameter, because the cirlce is cut in half
The answer is 65. you wouldn’t square it because the square root sign is still there. therefore the answer is square root of 65. you would be correct if the question was asking for the answer in the simplest form.
