Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
Now when k =1.6 , y = 40 then x will be
Therefore the value of x is 25 when y =40.
Answer:
7 1/4
Step-by-step explanation:
12 3/4- 5 1/2
Answer:
<h2>1.20</h2>
Step-by-step explanation:
1y + 12 = 6 (1y + 1)
1y + 12= 6y + 6
12 - 6 = 6y - 1y
6 = 5y
y = 6/5
y = 1.2
I don't what you meant by rounding to 2 decimal points so my answer is
<h2>1.20</h2>
Answer:
x = 3
Step-by-step explanation:
5(2 - x) = 7x - 26
Distribute;
10 - 5x = 7x - 26
Add 5x to both sides;
10 = 12x - 26
Add 26 to both sides;
36 = 12x
Divide both sides by 12;
x = 3
