When you graph y=4 it is a horizontial line going straight forever. You would mark a dot on postive four on the y-axis. For x, do the same thing mark on the negative three on the x-axis. But this one will be vertical.

3/16 equals -5/4+ G solve for G

Answers

Answer:

G = 23/16  OR  G = 1.4375

Step-by-step explanation:

3/16 = -5/4 + G

Get the constants on one side. Add 5/4 on both sides.

3/16 + 5/4 = G

To add fractions, find the common denominator. The smallest denominator between these two fractions is 16.

3/16 stays the same since it already has the denominator of 16. To turn the denominator (4) in 5/4 into 16, multiply it by 4. Whatever you do to the denominator, you must do to the numerator.

5 x 4 = 20

The second fraction is now 20/16

3/16 + 20/16 = 23/16

G = 23/16

The answer is : 23/16

Step by step:
3/16= -5/4 + G
3/16+5/4 = 3/16 + 20/16
G= 23/16

What is 3 1/2 as an improper fraction?

Answers

Answer:

7/2

Step-by-step explanation:

Step 1

Multiply the denominator by the whole number

2 × 3 = 6

Step 2

Add the answer from Step 1 to the numerator

6 + 1 = 7

Step 3

Write answer from Step 2 over the denominator

7/2

the improper fraction form of 3 1/2 is 7/2.

To convert the mixed number 3 1/2 to an improper fraction, we first multiply the whole number (3) by the denominator (2) and add the numerator (1). This gives us 3 * 2 + 1 = 7 as the new numerator. The denominator remains the same, which is 2. So, the improper fraction form of 3 1/2 is 7/2.

In this fraction, the numerator (7) represents the total number of parts we have, while the denominator (2) represents the size of each part. Therefore, 3 1/2 is equivalent to the improper fraction 7/2.
