A music school charges a registration fee in addition to a fee per lesson. Write an equation if each lesson costs $40 and a regi

Jobisdone [24]

T = total cost for music school
L = # of lessons

T = $1,190 + ($40 × L)
T = $1,190 + ($40 × 12)
T. = $1,190 + $480
T = $ 1,670 for 12 lessons

Answer:

y = - 2x + 1

Step-by-step explanation:

Substitute an x value from the table into the equation

x = 1 : y = - 2(1) = - 2 ← require to add 1 to obtain y = - 1

x = 4 : y = - 2(4) = - 8 ← require to add 1 yo obtain y = - 7

Then equation describing the relationship is

y = - 2x + 1

A square pyramid has a height of 6 units and a volume of 70 units3. if a square prism has the same base area and volume as the s

goldfiish [28.3K]

The height of the square pyramid exists 2 units.

<h3>How to estimate the area of the base of the square pyramid?</h3>

Volume of the square pyramid

$$V = \frac{1}{3}BH$

where B exists in the area of the base H lives at the height of the pyramid

we have H = 6 $$$unit^3$

V = 70 $$$unit^3$

substitute in the formula and solve for B, we get

$$70 = \frac{1}{3}B(6)$

B = $$\frac{70}{2}$

= 35 $$$unit^3$

To estimate the height of the square prism

Volume of the square prism = Bh

Where B exists the area of the base

h exists the height of the prism

we have B = 35 and V = 70

substitute in the formula and solve for h

70 = (35)h

h = 2 units.

If the expression 2x/a plus b = c is solved for x in terms of a, b, and c, then x = what?

Doss [256]

Answer:

The value of x in terms of a, b ans c is $x=\frac{ac-ab}{2}$

Step-by-step explanation:

We have given the expression $\frac{2x}{a}+b=c$

We have to find the value of x in terms of a, b and c

So $\frac{2x}{a}+b=c$

$\frac{2x}{a}=c-b$

$2x=a(c-b)$

$2x=ac-ab$

$x=\frac{ac-ab}{2}$

So the value of x in terms a ,b and c is $x=\frac{ac-ab}{2}$
