Answer:

1080

Step-by-step explanation:

We take x to be the number of pennies in the bank at first which filled the bank by a ¹/3

¹/3=×

⁷/9=×+480

⅓ multiply by 3 with both the numerator and denominator to get 3/9

7/9-3/9=4/9

4/9=480

If 4/9=480 what of 9/9

9/9×480÷4/9

Reciprocate 4/9

9/9×480×9/4=1080

Which of the following is not an example of like terms?
Viktor [21]

Answer:

A. 2 and-6

Step-by-step explanation:

Like terms are terms that contain the same variables raised to the same powers. In other words, they have the same variables with the same exponents.

So in option A, we have the terms 2 and -6. These terms are not like terms because they do not have the same variables.

HURRY !!
LekaFEV [45]

Answer:

B. In step 2, marquis should have interpreted the results as x _< - 9.2, which means that x is less than or equal to -9.2

Step-by-step explanation:

Step 1 is correct.

Step 2.

-9.2 >= x

Subtract x from both sides.

-x - 9.2 >= 0

Add 9.2 to both sides.

-x >= 9.2

Divide both sides by -1. When you multiply or divide both sides of an inequality, the inequality sign changes direction.

x <= -9.2

The first error is in Step 2.

Answer:

B. In step 2, marquis should have interpreted the results as x _< - 9.2, which means that x is less than or equal to -9.2
