Answer:
a = 3 7/18 or 3.388889
Step-by-step explanation:
First, you want to get the a by itself, so you would subtract 4 from the left side of the equals sign.
6a + 4 = 61 / 3 + 4
-4 -4
6a = 61 / 3
By doing that, they cancel each other out, so you are left with
6a = 61 / 3
Then you want to get a by itself, so you divide 6 from both sides.
6a / 6 = 61 / 3 / 6
Remember that 6 can also be written as 6/1
Remember that dividing a fraction is multiplying the reciprocal.
6a / 6 = 61 / 3 / 6 / 1
When dividing fractions remember to Skip the first fraction, Flip the second fraction, and Multiply the two fractions together.
61 / 3 x 1 / 6
skip multiply flip
Multiply across the top, and across the bottom.
61(1) and 3(6)
Then you get
61 / 18
So a = 61 / 18
If you want to convert that to a mixed number, it would be 3 7 / 18
If you want that in a decimal, it would be 3.388889
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
X/ 6.9 = 5/6
x = 6.9(5) / 6
x = 5.75
x = 5.8
or
x/ 6.9 =6/5
x = 6.9(6) / 5
x = 8.28
x = 8.3
answer is D.
8.3 cm , 5.8 cm
The answer is 0.023.
Hope this helps
<u>Step-by-step explanation:</u>
When you plug in 3 directly to the equation, you get 0/0
Since it is indeterminate, you have to use L'Hopital's Rule.
That means that you find the limit of the DERIVATIVE of the numerator and the DERIVATIVE of the denominator.
