Answer:
The proportion is 3/4=9/12
Step-by-step explanation: For proportions you need to write it in a ratio, after doing that, you look at the outside numbers on the ratio on this case it is 3 and 12, multiply that and you get 36, after that do the same with the inside numbers to get another 36.
Answer:
The answer is b. 72.3cm
Step-by-step explanation:
11.5cm is the radius
To find the circumference multiply the radius by 2 then multiply it again by 3.14
3.14 is the beginning of pi.
e.g - 2 × 3.14 x 11.5
10 (x/2 +6)=8
10x/2 +60=8
Subtract 60 from both sides
10x/2+60-60=8-60
10x/2= -52
Multiply both sides by 2
(10x/2)*2= -52*2
10x= -104
Divide both sides by 10
10x/10=-104/10
Answer: x= -10.4
4x-3=12
add 3
4x=15
divide 4
x=15/4
x=12/4+3/4
x=3+3/4
x=3 and 3/4
answer is 3 and 3/4
Y=|2x|
x=|2y|
x=2y
x/2=y
f^-1(x)=x/2
