Answer:
C
Step-by-step explanation:
swap y and x in the function. that is

we get x=4y+5
<em>S</em><em>o</em><em>l</em><em>v</em><em>e </em><em>for </em><em>y</em>
(x-5)/4=y

a = 56
given 28 =
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True
Answer:
134/300 or 67/150
Step-by-step explanation:
the LCM of 15 and 100 is 300. 15 *20 is 300 so we multiply both the numerator and denominator of 1/15 by 20 to get 20/300, with 38/100 we multiply by 3 to get 114/300. Now we add 20/300 and 114/300 to get 134/300 which has a common factor of 2 so we can simply it to 67/150
Answer:




Step-by-step explanation:
<u>Given information</u>



<u>Derived expression from the given information</u>
<em>Presumably, I think this is a combination of segments</em>

<u>Substitute values into the given expression</u>

<u>Combine like terms</u>
<em>The following is the expression</em>
