Answer:
8:11
Step-by-step explanation:
That is a ratio, but you can further simplify by dividing each side of the ratio by the same numbers. Start with basic ones you know, for example 50 will go into both evenly.
3600/50:4950/50
72:99
Keep dividing each side until you can't make even numbers.
72/9:99/9
8:11
Answer:
<h3>X=18</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
<u><em>DISTRIBUTIVE PROPERTY:</em></u>
A(B+C)=AB+AC
A(B-C)=AB-AC
2(3x – 4) + 10 = 5(x + 4)
2(3x-4)+10 (First, expand by using distributive property.)
2*3x=6x
2*4=8
6x-8
6x-8+10
-8+10 (Add and subtract.)
-8+10=2
6x+2
5(x+4)
5*x=5x
5*4=20
5x+20
6x+2=5x+20
6x+2-2=5x+20-2 (Subtract 2 from both sides.)
20-2 (Solve.)
20-2=18
6x=5x+18
6x-5x=5x+18-5x (Then, subtract 5x from both sides.)
18-5x (Solve.)
18-5x=18
x=18
So, the correct answer is x=18.
Answer:
100.48
Step-by-step explanation:
Step 1: Find the diameter
16 × 2 = 32
Step 2: Multiply by pie (Usually just 3.14)
32 × 3.14 = 100.48
