A. 4y² - 2y²
B. 2y² + 18x
C. 4y² + 6x - 2y² + 12x
D. 6x + 12x

Answers

Answer 1
2y^2 + 18x

4y^2 and -2y^2 combine as like terms to make 2y^2

6x and 12x combine as like terms to make 18x
Answer 2

Answer:

B or 2y² + 18x

Step-by-step explanation:

4y² + 6x - 2y² + 12x

combine like terms together:

4y² + (-2y²) = 2y²

6x + 12x = 18x

2y² + 18x = B

Create and Solve an equation to find the unknown angle. ​

Answers

Answer:

Equation: 2x + 3x + 10 = 180

x = 34

Top angle = 68 degrees

Bottom angle = 112 degrees

Step-by-step explanation:

The two angles add to 180, so set them equal to 180.

2x + 3x + 10 = 180

5x + 10 = 180

     - 10    - 10

5x = 170

/ 5    / 5

x = 34

Plug x into angles,

2(34) = 68

3(34) + 10 = 112

John wanted to save money to buy a new outfit. John saved $28.80 in April, $21.90 in May and $21.00 June. However, he also had to spend $28.60 on school supplies and $43.50 on his dog. if the outfit costs $182.60, how much money does John still need to save?

Answers

To solve this question you would need to calculate the amount of money he saved:
28.80+21.90+21=$71.70
Now you would need to subtract everything he spent his money on:
71.70-28.60-43.50=$4.60
Now you would need to do
182.60-4.60=$178

So John would have to save $178 to buy his new outfit. :-)
$175.40 ( 2 decimal place if its in dollars )

working:

Total save before spending: $79.3
After spending $79.3 - $ 28.60 - $43.50= $7.2
How much josh need to save: $182.60-$7.2 = $175.4
