y = 6 - 3x
x + y = 62
Since we already know the value of y, we can use substitution to find the value of x.
x + 6 - 3x = 62
<em><u>Subtract 6 from both sides.</u></em>
x - 3x = 56
<em><u>Combine like terms.</u></em>
-2x = 56
<em><u>Divide both sides by -2</u></em>
x = -28
Now that we know the value of x, we can solve for the value of y.
x + y = 62
-28 + y = 62
<em><u>Add 28 to both sides</u></em>
y = 90
The value of y is 90, and the value of x is -28 (this is your answer)
To make sure that these values are correct, we can plug them into the original equations.
y = 6 - 3x
x + y = 62
90 = 6 - 3(-28)
90 = 90 √ this is correct
-28 + 90 = 62
62 = 62 √ this is also correct

Do u need help with all of them
The answer would be 18+54 because when you distribute the 6 to the numbers that are inside the parenthesis (6*3=18 6*9=54) When you add 18 and 54 together I would get 72. 18+54 is 72. 18+9 is 27. 9+15 is 24. 6+54 is 60. Pick the one that gives you an answer of 72 which was 18+54. I hope this helped you!
You first multiply 7 by itself 4 times which is 2401. Then you divide by 25 because 5 to the power of 2 is 25. Then you multiply by itself 3 times which gives you 885,842.381
Answer:
Lana has 6 more candy bars than Markus.
Step-by-step explanation:
Lana has 6 bags, each with 3 candy bars. To find the total amount you multiply 6 by 3 which is 18. Markus has 3 bags, each with 4 candy bars, to find the total amount you also multiply 3 by 4 which is 12. Now you subtract: 18-12=6. So Lana has 6 more candy bars than Markus.
