30 * 0.05 + 1 = X
1.5 + 1 = X
2.5 = X
The light remains yellow for 2.5 seconds on a street with a speed limit of 30.
Answer:
1.125 h = 1h 7.5 min = 1 h 7 min 30 sec
Step-by-step explanation:
John makes 1/1.5 work per h.
His partner makes 1/4.5 work per h.
Together they make (1/1.5 + 1/4.5) = (3/4.5 + 1/4.5) = 4/4.5 work per h.
They will work
1 : 4/4.5 = 4.5/4 = 1.125 h = 1 h + 0.125 h = 1h + 0.125h*60min/1h =
=1h 7.5 min = 1 h 7 min 30 sec
Yes, you are correct. Suppose the relationship is p=aq. Put p=10 and q=2 in, we can get p=5q. So when q=20, p=20*5=100. So the answer is D. Be confident with yourself~
Answer:
<h2>
The more complex answer:</h2>
x: number of days
y: number of total pounds.
For 12 elephants, we have the expression is:
Then, for the given number of days, we have x = 5.
Substituting the value of x we have:
an expression to represent the number of pounds of food a herd of 12 elephants eat in 5 days is:
<h2>
the easy answer:</h2>
The find the answer for this particular question you would you would multiply 12 by 300 which is 3600, and you would then multiply that by 5 which is 18000
Answers:
1. Switch sides
2. Subtract by 8 from both sides of equation.
3. Simplify.
4. Multiply by -1 from both sides of equation. (it's should be the reverse inequality).
5. Simplify.
6. Then you had to divide by 9 from both sides of equation.
7. Simplify.
8. Divide by the numbers.
9. Divide by the numbers.
