Answer:
30. $<u>25.42</u>
31. $<u>21.48 </u>
32. $<u>23.06</u>
Step-by-step explanation:
30. 8.54+7.50+9.38 = 25.42
31. 6.99+5.99+8.50 = 21.48
32. 8.50+5.33+9.23 = 23.06
Answer:
-171=y
Step-by-step explanation:
-the 1 from both sides; then divide by -1
Answer:
f x + 2f + 4.
Step-by-step explanation:
<h3>The constant of variation is

</h3><h3>The equation is

</h3>
<em><u>Solution:</u></em>
Given that,
The conversion of square feet to square yards can be represented by direct variation
Let y represent the number of square yards
Let x be the number of square feet

y = kx ------ eqn 1
Where, "k" is the constant of variation
Three square yards are equivalent to 27 square feet
Substitute, y = 3 and x = 27 in eqn 1

Thus the constant of variation is 
<em><u>What is the equation representing the direct variation?</u></em>
Substitute k = 1/9 in eqn 1

Thus the equation is found
