In order to solve this we'll start by assigning variables to hamburgers and cheeseburgers, since these are what we're trying to find. Lets say x = hamburgers and y = cheeseburgers. So we know two things, we know that x+y= 763 (hamburgers plus cheeseburgers sold equals 763, and we know that y= x+63 (cheeseburgers sold equals 63 more than hamburgers sold). Now we have a system of equations. This can be solved most easily by rearranging each equation to each y, and then set them equal to each other:
x+y=763 -> y=763-x, and we already have y=x+63. Set them equal to each other:
x+63 = 763-x (add x to both sides) -> 2x+63 = 763 (subtract 63 from both sides) -> 2x = 700 (divide both sides by 2) x = 350. So we solved for x, which is hamburgers sold, which is what the question asks for, so your answer is 350 hamburgers were sold on Saturday
Answer: Lydia’s new balance would be $12.26.
Explanation:
Deposit means add so,
-18.24+30.50=12.26
Now Lydia will have $12.26 in the account.
(4,-1). 4x+3y=13. You do 4(4)+3(-1)=13. hope that helps.
The statement that is true is f(-2)=g(-2), if i did the math correctly :)
Answer:
2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)
Step-by-step explanation:
Given the expression 6 + 12x.
The following functions are equivalent;
Factoring out common number;
For 2;
2(3) + 2(6x)
2 (3 + 6x)
Factoring out 3;
3(2) + 3(4x)
3 (2 + 4x)
Factoring out 6;
6(1) + 6(2x)
6 (1 + 2x)
Hence the possible equivalent expressions are 2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)
