What is 4c minus 7.8 if c is 4

Mathematics
1 answer:
Debora [2.8K]3 years ago
5 0
Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.

c = 4

4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2

Hope this helps! :)

Step by step plz <br> 2x^2 + x - 3
Aleks04 [339]

Answer:

x = 1 or x = -3/2

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + x - 3 = 0

The left hand side factors into a product with two terms:

(x - 1) (2 x + 3) = 0

Split into two equations:

x - 1 = 0 or 2 x + 3 = 0

Add 1 to both sides:

x = 1 or 2 x + 3 = 0

Subtract 3 from both sides:

x = 1 or 2 x = -3

Divide both sides by 2:

Answer: x = 1 or x = -3/2

Is 5/6 closer to 1 or 0
Tasya [4]
The easiest way to think about this is to give all of the numbers common denominators:
1 can be written as 6/6
0 can be written as 0/6

Now we can see that 5/6 is only 1/6 away from 1, while it is 5/6 away from 0.

So, 5/6 is closer to 1!
