Answer:
Katie needs to pay $27.9.
Step-by-step explanation:
Given;
Cost of per foot = $2.25
Number of flowers in her yard = 12.4 square foot
We need to find how much she needs to pay.
Solution:
Now we know that;

So for
= Cost for
.
By using Unitary method we get;
Cost for
= 
Hence Katie needs to pay $27.9.
Answer:
1. Evaluate 3y - 4 for y =5
3*(5)-4=15-4=11
2. 65 + x = 99 x = ?
65+x=99
x=99-65
x=34
3. Find the product. 38.7 *21
38.7*21=812.7
4. Which value satisfies the equation? 9x + 3 = 30
The right value for x would be:
9x+3=30
9x=30-3
9x=27
x=27/9=3
Step-by-step explanation:
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
