Answer:
no
Step-by-step explanation:
5x would be multiplying 5 and x. So, if x=4, then 5x would be 20, and 20+10=30. But if you did 10x+5, it would be 40+5 which is 45. Therefore, the answers would not be the same.
y=13.34 when x=15
Step-by-step explanation:
We are given that x varies directly with y i.e y ∝ x
We know that: y ∝ x then
y= k/x
where k is constant.
So, if y=10 and x=20 we can find k
Now, we need to find y when x=15
We know that k = 200,
So, 
So, y=13.34 when x=15

Let’s take Sanku as x.
if Madhu is 3 times his age, then he is 3x.
the difference in their age is 14, so
3x - x = 14
2x = 14
x=7
Sanku is 7
Madhu is 21
The equation from the image is the one
Answer:
x = 6
Step-by-step explanation:
first you would put them equal because they have the same angle: 9x + 10 = 2x + 52
subtract 10 from both sides: 9x = 2x + 42
subtract 2x from both sides: 7x = 42
divide by 7 on both sides x = 6
hope this helps! :)
