-12-x&gt;-12+4x<br> put the steps too pls thanks
andrey2020 [161]

Answer:

x < 0

Step-by-step explanation:

Firstly put the values with variable x to one side,

; -12 - x > -12 + 4x

; -12 + 12 > 4x + x

; 0 > 5x

then divide both sides by 5,

; (0 ÷ 5) > (5x ÷ 5)

; 0 > x

; Hence the solution to the inequality above,

; x < 0...always remember to reverse the sign when you change the side to which you put the variable of x,

Therefore...( x < 0 )

How can u tell when a rate is a unit rate
r-ruslan [8.4K]
<span>When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>

two similar triangles have a scale factor of 3:5. the altitude of the larger trangle is 24 inches. what is the altitude of the s
Andreyy89
The altitude of the smaller triangle will be given as follows:
let the altitude of the smaller triangle be x
scale factor of small to large triangle is 3:5
but
scale factor=(length of small Δ)/(length of large Δ)
plugging in our values we get:
3/5=x/24
solving for x we get:
x=3/5×24
x=14.4 inches

Answer: 14.4 inches

Someone help me out please
Rufina [12.5K]

Answer:

\displaystyle x=\frac{5}{4},\;\;1\frac{1}{4},  \;\; or \;\; 1.25

Step-by-step explanation:

    To solve for x, we need to isolate the x variable.

    Given:

\displaystyle x+\frac{1}{2} =\frac{7}{4}

    Subtract \frac{1}{2} from both sides of the equation:

\displaystyle (x+\frac{1}{2})-\frac{1}{2} =(\frac{7}{4})-\frac{1}{2}

\displaystyle x=\frac{7}{4}-\frac{1}{2}

    Now, we will create common denominators to simplify.

\displaystyle x=\frac{7}{4}-\frac{2}{4}

\displaystyle x=\frac{5}{4}
