Answer:

a=7

Step-by-step explanation:

1) Add 15 to both sides

3a=6+15

2) Simplify 6+156+15 to 21

a=21/3

3) Simplify the fraction 21/3 to 7.

Suppose that x and y vary inversely, and x = 7 and y=11. Which function models the inverse variation?Answers:Y=1.57xY=77/xY=4/xY

sdas [7]

Answer:

Y=77/x

Explanation:

Y varies inversely with x meaning

$y\propto\frac{1}{x}$

adding a proportionality constant gives

$y\propto\frac{k}{x}$

Now, we are told that y = 11 and x = 7; therefore, the above gives

$11=\frac{k}{7}$

Solving for k gives

$k=77$

Therefore, the function that models the inverse variation is

$y=\frac{77}{x}$

which is our answer!

Find the area and the circumference of a circle with diameter 3 ft.

Zigmanuir [339]

Step-by-step explanation:

circumference of a circle

2×pi×r

area of a circle

pi×r²

r (radius) = diameter/2 = 1.5ft

we shall assume pi to be 3.14

circumference is

2×3.14×1.5 = 3.14×3 = 9.42 ft

area is

3.14 × 1.5² = 3.14×2.25 = 7.065 ft²

konstantin123 [22]

Each hot dog is x, and costs $4. Each soda is y, and costs $3.

4x + 3y = 33

4x + 3y = 33

4 * 3 + 3y = 33

12 + 3y = 33

3y = 21

y = 7

7 bottles of soda.
