Step-by-step explanation:
For starters there is only one answer to every math question if you get an answer make sure it is correct
Answer:
a) 1/2
b) 6/100
c)1/4
I'll explain how I got these answers later.
Answer:
Add 22/63
Step-by-step explanation:
3/7 + n = 7/9
<u>Step 1: Subtract 3/7 from both sides</u>
3/7 + n - 3/7 = 7/9 - 3/7
n = 49/63 - 27/63
n = 22/63
Answer: Add 22/63
The table is proportional and the constant of proportionality is 1.5
Step-by-step explanation:
Proportional relationships are relationships between two variables
where their ratios are equivalent
- One variable is always a constant value times the other
- The relation between the two variables represented graphically by a line passes through the origin point
The table:
→ x : 0 : 2 : 4 : 6
→ y : 0 : 3 : 6 : 9
To prove that y ∝ x find the ratio between each value of y with corresponding value of x
∵ 
∵ 
∵ 
∴ 
∴ k = 1.5
∵ The origin point is in the table
∴ y ∝ x
∴ The table is proportional
The table is proportional and the constant of proportionality is 1.5
