Answer:
Greater than
Step-by-step explanation:
you are adding exponent with the same denominator if its easier for you in this example you can set the denominator equal to 10.
Sum= adding
2/5 +4/5 =6/5 or 1 1/5
if you want to do it with the denominator equal to 10 just multiply each side by 2.
(2/5 +4/5)x 2
4/10 + 8/10 = 12/10
Answer:
Step-by-step explanation:
can be said as " divided by 
", so the ? is .
Using the magic of algebra!:
The time each train goes in 1 hour will be represented as a / b.
b is 30 more than a, so if we add 30 to a it should equal b.
a + 30 = b
In three hours, the trains are 330 miles apart.
Esentially, we're adding up the distance each train goes from the starting point to find the distance between them.
3b + 3a = 330
Now we have a system of equations to solve.
a + 30 = b
3b + 3a = 330
We want to get the variables on seperate sides of the equation for easy solving.
a + 30 = b
3b = 330 - 3a
Then get the value of the one variable the same so we can use the transitive property.
a + 30 = b
b = 110 - a
a + 30 = 110 - a
2a + 30 = 110
2a = 80
a = 40 mph
(And thus b = 70 mph)
Your answer would be
12816
25 percent of people had pasta.
First add 450 and 150 (which equals 600)
Next divide 600 by 150 (which equals 4)
Which means 150 is a fourth of six hundred, and a fourth is 25 percent.
Which leads to my answer of 25 percent
