The 1st stage: x, the 2nd stage: y.
x + y = 152
x = y + 28
y + 28 + y = 152
2 y = 152 - 28
2 y = 124
y = 124 : 2 = 62
x = 62 + 28 = 90
Answer: the first stage burns 90 seconds and the second burns 62 seconds.
Answer:
Step-by-step explanation:
4
If you put 4 with another 4 the total is 8. The two lines must be greater than the third. Equal is not good enough.
The other lengths will produce triangles with 4 and 8. Any 2 will be greater than the third.
Answer:
8/12
Step-by-step explanation:
First
12 divided by 3 = 4
Second
since 12/3=4 you multiply 3x4 to get 12 so what you do to the denominator you do to the numerator so 2x4=8
Last
so that would give you
2/3 = 8/12
