1) First, solve one linear equation for y in terms of x .

2) Then substitute that expression for y in the other linear equation.

3)Solve this, and you have the x -coordinate of the intersection.

4)Then plug in x to either equation to find the corresponding y -coordinate.

Is 0.26 is closer to 0, 1/2 or, 1
professor190 [17]
Here, we know 1/2 = 0.50
So, the difference between 0.50 & 0.26 is 0.24
And difference between 0 and 0.26 is 0.26
1 is very apart from 0.26 as compared to other two

So, It is closer to 1/2

Hope this helps!

0.8/y =2: 3/4 Please help
bulgar [2K]

Answer:

0.3

Step-by-step explanation:

0.8/y = 2 : 3/4

The value of y in the above expression can be obtained as follow:

0.8/y = 2 : 3/4

0.8/y = 2 ÷ 3/4

0.8/y = 2 × 4/3

0.8/y = 8/3

Cross multiply

0.8 × 3 = y × 8

2.4 = 8y

Divide both side by the coefficient of y i.e 8

y = 2.4/8

y = 0.3

Thus, the value of y is 0.3
