B + 4b = 8
You have to combine the like terms and then divide both sides by the coefficient to isolate the variable b.
<em>b + 4b = 8
</em>5b = 8
(5b / 5) = 8 / 5
b = 1.6
Since it says to round to the nearest hundredth, I would just put a zero right after the tenths place.
b = 1.60
x 3
Step-by-step explanation:
Answer:
Least common denominator of 2 and 8: 8
5 x 1 = 5
8 x 1 = 8
1 x 4 = 4
2 x 4 = 8
Step-by-step explanation:
5/8 and 1/2 are not equivalent; the wording is weird on this question, it almost makes it sound as if it wants you to make 5/8 and 1/2 equivalent fractions.
I assume it only wants you to set it up so that in part 2 you will be able to easily figure out how much wire Mr. Barber has used total. Which will be 9/8 yards, by the way. Alternatively, 1 1/8 yards.
The area of a circle by definition is given by:
A = pi * r ^ 2
Where,
r: radius
Substituting the values we have:
A = (3.14) * (15) ^ 2
A = 706.5 mm ^ 2
Answer:
The approximate area of the compass is:
A = 706.5 mm ^ 2
Around 35-45 minutes, but it depends on the size of the container.
