Answer:
x = 15
y = 2
Step-by-step explanation:
X-4y=7 | ×6 |
-6x-3y=12 | ×1 |
6x - 24y = 42
-6x - 3y = 12
___________+
27y = 54
y = 54/27
y = 2
x - 4y = 7
x - 4(2) = 7
x - 8 = 7
x = 7 + 8
x = 15
Answer:
3. 26 problems left
4. $69.20
Step-by-step explanation:
1. First I divided 5 into 2 to get a decimal, 0.4, and then I multiplied 0.4 to 65.
0.4 x 65 = 26
2. It said that Luke paid 2.75 for himself and 6 other friends, which is 7 people. I then multiplied 2.75 x 7 and got 19.25. I then added 19.25 to the other amount of money, and got 69.20.
49.95 + 19.25 = 69.20

Answer:
a = 729/3^-1
Step-by-step explanation:
Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.
Hope this helps
