Order of operations rules are important here: n/4-13
We must do the division first. Thus, n/4-13 translates to "the quotient of n and 4, less 13."
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:
£6,000
Step-by-step explanation:
<u>Use the simple interest formula:</u>
I = Prt
I = (Principal Value)*(Annual Interest Rate)*(Time in Years)
I = (120000)(0.12)(5/12)
I = 6000
Therefore, the simple interest is £6,000
