Answer:
1.5 hours
Step-by-step explanation:
1/2 + 1/2 + 1/2 =1.5
Answer:
1.2
Step-by-step explanation:
142.
You can get this by seeing what number you have to multiply 7 by to get as close to 1000 as you can. 7*142 = 994. Thus each one of the multiplications up to that point will give you a positive integer than can be divided by 7. <span />
For this case, the first thing we must do is define variables:
x: Jane's age
y: Helen's age
By writing the system of equations we have:
y = x + 8
y-20 = 3 (x-20)
Solving the system we have:
x = 24
y = 32
Answer:
Jane is 24 years old
Helen is 32 years old
the equation for Jane would look like:
x + 8 = 3 (x-20) + 20
Answer:
1.50x < 12 (the inequality would just be "less than")
