In the number 54, 625 from left to right:
5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000
so
<span>
54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5
another way we can write this number is </span>

Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii)

2 ways, which are essentially the same thing.
Answer:
g(x) = f(x) + 2
Step-by-step explanation:
To move the two to the other side of the equation, you have to add the two to both sides of the equation. The 2 cancels out on the g(x) side, and a 2 is added to the f(x) side.
Answer:
60
Step-by-step explanation:
Sam is 5, Tom is 3 times as old, 5 times three is 15, so tom is 15, 20 is 4 times 5, so you take 15, and multiply it by 4, and that's your answer
Answer:
y = 3x - 10
Step-by-step explanation:
Step 1: Rewrite 1st equation
2y = 6x + 4
y = 3x + 4
Step 2: Find 2nd equation
y = 3x + b
-4 = 3(2) + b
-4 = 6 + b
b = -10
Step 3: Rewrite 2nd equation
y = 3x - 10
And we have your parallel equation!
Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
