The equation is:
12.99 + 2.10b = 21.39
Subtract 12.99 from each side to get:
2.10b = 8.4
Then divide to find the amount of bottles:
b = 4 bottles

Hope this helps!! :)

-6a÷[3(1-1/2a)-(2/3-3a)-a] a=-1

e-lub [12.9K]

Step-by-step explanation:

$\frac{ - 6a}{(3(1 - \frac{1}{2} a) - ( \frac{2}{3} - 3a) - a)a } = - 1 \\ \frac{ - 6a}{( \frac{3}{2} a + \frac{7}{3}a - a)a } = - 1 \\ \frac{6a}{ \frac{17}{6} a {}^{2} } = 1 \\ 6 = \frac{17}{6} a \\ a = \frac{(6 \times 6)}{17} \\ a = \frac{36}{17}$

-3(-5)-3y=-6 find the value of y

julia-pushkina [17]

-3 (-5) - 3y = -6

15 - 3y = -6

-3y = -6 + (-15)

-3y = -21

y = -21 / -3

y = 7

The value of y is 7.

Solve for x in a right triangle (show work)

AnnZ [28]

Answer:

35.09°

Step-by-step explanation:

You can use cos theta to find the value of x.

Let us solve now.

They have already given the lengths of the hypotenuse and adjacent.

Hypotenuse = 33

Adjacent = 27

Let us solve now.

Cos x = Adjacent ÷ Hypotenuse

Cos x = 27 ÷ 33

Cos x = 0.8181

x = Cos⁻¹ 0.8181

x = 35.09°

Hope this helps you :-)

Let me know if you have any other questions :)
