Answer:
3 + 3.75x=18
subtract 3 from both sides
3.75x=15
divide by 3.75 on both sides
x=4

Answer:
351.68 cm^2
Step-by-step explanation:
We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)
Answer:
x=13
Step-by-step explanation:
one angle of triangle=85
parallel lines and vertical angles
the second angle is 82:
sum of angles of the triangle=180
x+85+82=180
x+167=180
x=180-167
x=13
Answer:
the answer is b
Step-by-step explanation:
is b because if you you multiply 5/6 x 3/4 it will equal 30/24 if you reduce it it will be 5/4 which is bigger then 3/4
