good luck
<span>Simplifying
4.5 = 2a
Solving
4.5 = 2a
Solving for variable 'a'.
</span>
<span>Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
4.5 + -2a = 2a + -2a
</span>
<span>Combine like terms: 2a + -2a = 0
4.5 + -2a = 0
</span>
<span>Add '-4.5' to each side of the equation.
4.5 + -4.5 + -2a = 0 + -4.5
</span>
<span>Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -2a = 0 + -4.5
-2a = 0 + -4.5
</span>
<span>Combine like terms: 0 + -4.5 = -4.5
-2a = -4.5
Divide each side by '-2'.
a = 2.25
Simplifying
a = 2.25
Let's check: 2 x 2.25 = 4.5
Next time, follow these steps and you will pass
Hope I helped :)

The answer is 5 because 5 is a factor of 15 but not a multiple of 5
Because 21 is more than 1
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.
