Answer:
x = 3
y = 1
Step-by-step explanation:
(2x + 4y = 10) * 2 = (4x + 8y =20)
4x = 20 - 8y
Plug that into the other equation
(20 - 8y) - y = 11
-9y = -9
y = 1
Plug this value into one of the original equations
2x + 4(1) = 10
2x = 6
x = 3
Answer:
Alex is right so the problem is solved
subtract 1/3x
so that you can get qui equatio
Answer: It should be 270 ml
Step-by-step explanation:
To find 3/8 of 720, we need to know 1/8
Divide 720 by 8, this gives you 90
Now multiply 90 by 3 to get 3/8
Answer is 270 ml
I'm not sure how to write the rule, but every time you add one more to the sum of the last two. First, you add 1, then 2, then 3. 1+1=2 2+2=4 4+3=7 7+4=11 and so on. I hope this helps!
