Answer:

b < 11 = The baby weighs at least 11 pounds.

b > 11 = The box contains more than 11 books.

b < 12 = There are fewer than 12 beetles in a jar.

b > 12 = The building is taller than 12 feet.

Step-by-step explanation:

The baby weighs at least 11 pounds is b < 11 because the baby weighs more than 11 pounds.

The box contains more than 11 books is b > 11 because there are more books in the box than 11.

There are fewer than 12 beetles in a jar is b < 12 because there are less than 12 beetles in a jar.

The building is taller than 12 feet is b > 12 because 12 feet is less than how tall the building is.

(4y + 3)<br> (5x - 7)<br> (3x + 17°<br> X= ,y= ,
Kryger [21]

Answer:

Simplifying

4y + 3 = 5x + -7 + 3x + 17

Reorder the terms:

3 + 4y = 5x + -7 + 3x + 17

Reorder the terms:

3 + 4y = -7 + 17 + 5x + 3x

Combine like terms: -7 + 17 = 10

3 + 4y = 10 + 5x + 3x

Combine like terms: 5x + 3x = 8x

3 + 4y = 10 + 8x

Solving

3 + 4y = 10 + 8x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 4y = 10 + -3 + 8x

Combine like terms: 3 + -3 = 0

0 + 4y = 10 + -3 + 8x

4y = 10 + -3 + 8x

Combine like terms: 10 + -3 = 7

4y = 7 + 8x

Divide each side by '4'.

y = 1.75 + 2x

Simplifying

y = 1.75 + 2x
