To simplify this all you need to do is distribute the 4x across each term in the parenthesis
The ratio of suitcases to screened suitcases is 36:8. The second ratio is 180:?.
--
180 is 5 times 36 which can be proven by dividing 180 by 36.
180 ÷ 36 = 5
Multiply 5 by 8 to find the amount of suitcases that would be screened if there were 180 total suitcases.
5 × 8 = 40
The first ratio is 36:8, and with a scale factor of 5 we get the second equivalent ratio 180:40.
<h2>Answer:</h2>
<u>Forty suitcases</u><u> will be screened.</u>
I hope this helps :)
Here are the original equations:
2x + 2y = 14
x + 2y = 11
We immediately note that these two equations form a system. So, we can use substitution to solve the second equation for x. To do this, all that needs to be done is to subtract 2y from both sides, to get x = 11 - 2y. Next, we substitute the derived expression for x into the first equation to get 2(11-2y) + 2y = 14. We can use the distribute property to get 22 - 4y + 2y = 14. Then, we can combine like terms to get 22 - 2y = 14. After that, we subtract 22 from both sides to get -2y = -8. Finally, we divide -2 from both sides to get y = 4.
Now that we have the value for y, we can substitute our derived value into the second equation, since it will be much faster. After doing this, we get x + 2(4) = 11. We can simplify the left side of the equation and subtract the product from both sides, which gives us x = 4. Therefore, the answer to your query is x = 4, y = 4. Hope this helps and happy Halloween!
Answer:
2
Step-by-step explanation:
2 squared is 4. 3 x 2 = 6. 6+4=10
The inequality has to be pointing at 250 since that’s the maximum of money they can spend so B and D are out. If you did the math and solved it, the answer would be 7.5 and rounded up which is 8 hours.
