Subtracting fractions with unlike denominators

Mathematics
1 answer:
lawyer [7]3 years ago
3 0

Answer:

3/12 or simplified 1/4

Step-by-step explanation:

First make the denominators the same. We can make 12 the common denominator. To make 3/4 have a denominator do the following:

Multiply the numerator and denominator by 3 since 4x3=12. The new number becomes 9/12.

Then subtract:

9/12-6/12=3/12  The numerator subtracts while the denominator stays the same.

We can simplify 3/12 to 1/4

Henry has three metal rods. The three metal rods measure 7 feet, 9 feet, and 2 feet.
ankoles [38]

Answer:

No, Henry cannot form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of the lengths of two sides must be greater than the third side.

7 (first side) + 2 (second side) = 9

The sum of these two sides is not greater than the third side (9).

So, therefore, Henry cannot form a triangle.

Expand then sliplify : 3z (2z +4) + 6z (2z - 5)
klio [65]
Let's expand first:
6z^2+12z+12z^2-30z

Simplify (combine like terms):
18z^2-18z
18z(z-1)

So, your most simplified answer is 18z(z-1) or 18z²-18z.

What does -3+7y=5x+2y Equal<br> (I’m bad at math)
bogdanovich [222]

Answer: 22 /5

-3+7y=5x+2y

Step-by-step explanation:

Subtract 2y from each side

-3+7y-2y=5x+2y-2y

-3 +5y = 5x

Add 5 to each side

5y = 5x+3

Divide each side by 5

y = 5x/5 +3/5

y = x +3/5

Let x = -5

y = -5 + 3/5

y = -25/5 +3/5

y = -22/5

Step-by-step explanation:
