Describe using words how to solve the equation 3-5n=-22

1 answer:

5 0

3 - 5n = -22

You're essentially just trying to get "n" isolated, or by itself.

So, in order to do that, we must move anything that doesn't have a variable in it onto the other side of the equal sign.

To do that, we must subtract 3 from both sides.

-5n = -22 - 3

Then, we simplify our equation.

-5n = -25

Then, we have to divide both sides by -5, so that we get the answer for "n."

-5n ÷ -5 = -25 ÷ -5

Simplify this.

n = -5

Answer:

$\Large \boxed{\mathrm{\bold{C}}}$

Step-by-step explanation:

$\sf \displaystyle sin(\theta) =\frac{opposite}{hypotenuse }$

$\sf \displaystyle sin(L) =\frac{x}{y}$

$\sf \displaystyle sin(H) =\frac{x}{z}$

$\displaystyle \sf \frac{sinL}{z} =\frac{sinH }{y}$

$\displaystyle \sf \frac{\frac{x}{y} }{z} =\frac{\frac{x}{z} }{y}$

Simplifying the expression.

$\sf \displaystyle \frac{x}{yz } = \frac{x}{yz} \ (true)$

$\displaystyle \sf \frac{z}{sinL} =\frac{y}{sinH}$

$\displaystyle \sf \frac{z}{\frac{x}{y}} =\frac{y}{\frac{x}{z}}$

Multiplying both sides by x.

$\sf yz=yz \ (true)$

A glass is 4/7 full. Then 70 cm³ orange juice is poured in. The glass is now 3/4 full.

Nataly_w [17]

Answer:

The volume of the glass is 217.8 cm³

Step-by-step explanation:

If the glass were initially 4/7 full, that means 3/7 of the volume is still available to hold more juice.

Let v represent the volume of the glass.

Then (3/7)v + 70 cm³ = (3/4)v.

We need to solve this for v.

Here the LCD is 28. Thus,

(3/7)v + 70 cm³ = (3/4)v → (12/28)v + 70 cm³ = (21/28)v.

Subtracting (12/28)v from both sides, we get:

70 cm³ = (9/28)v.

We can isolate v by mult. both sides by the inverse of 9/28, which is 28/9:

(28/9)(70 cm³) = v

The volume of the glass is 217.8 cm³

Answer:

Step-by-step explanation:

All the degrees of a triangle should add up to 180 degrees.

D = F

D and F are not equal to 90.

If E = 30, D and F both equal 75.

75(2) + 30 = 180.

professor190 [17]

Answer:

23.1%

Step-by-step explanation:

Given data

monthly taxable income was $3276.54

Tax= $757.24

Percentage of tax paid= tax paid/monthly income* 100

Percentage of tax paid=757.24/3276.54* 100

Percentage of tax paid=0.231* 100

Percentage of tax paid=23.1%
