Answer:
False
Step-by-step explanation:
Multiply 8 by 2 to create the common denominator (which is 16).
Now multiply 4 by 2 to keep the fraction even.
This gives you the fraction 8/16 which is not equivalent to 10/16.
Another way you could write this inequality:
8/16 < 10/16
Answer:
the third one
Step-by-step explanation:
search up 30 - 60 - 90 triangle rule for references
x is the number of adults and y is the number of children.
x + y = 12
<span>14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
</span>14x + 10y = <span>140
</span>-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = <span>12
</span>5 + y = <span>12
</span>y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
5.25 / .85 you would get 6.17~ but you cant sell 1/4th a cup, so you have to round up, making it 7 cups.
The sum in sigma notation for the sequence will be as follows:
From
<span>5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)</span>∑(5(n-1)+5)
