Answer: GCF = 14
Step-by-step explanation:
The factors of all numbers:
14 - 2, 7, 14
28 - 2, 4, 7, 14, 28
42 - 2, 7, 14
As you can see, 14 is our GCF.
Answer:
3/8
Step-by-step explanation:
Rewrite the equation with the parts separated
= 1 + 1/8 - 3/4
Solving the fraction part
1/8 - 3/4
Find the LCD of 1/8 and 3/4 and rewrite to solve with the equivalent fractions.
LCD = 8
1/8 - 6/8 = - 5/8
Combining the whole and fraction parts
1 - 5/8 = <u><em>3/8</em></u>
Answer:
8=w, -8=w (±8=w)
Step-by-step explanation:
192=
First, divide by 3
64=w²
now take the square roots of 64 and w² ( we're thinking about which numbers/variables will be multiplied to get 64 and w². They are 8 and w. But wait! -8 can also work, since when you square it a negative number, it will turn positive. )
8=w, -8=w
You can also write it as ±8=w
Hope this helps!
