Answer:

4.5 inches

Step-by-step explanation:

The scale factor is 1:20 which is 1/20, and the actual height is 90 inches.

First, write down the proportion:

1/20 = x/90

Multiply both sides by 90.

=> x = 90/20

=> x = 4.5in

Therefore, the height of the model is 4.5 inches.

Hope this helps :)

X-5(x-1)=2x-(2x-3) answer the question
levacccp [35]

Answer: x= 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x−5(x−1)=2x−(2x−3)

x−5(x−1)=2x+−1(2x−3)(Distribute the Negative Sign)

x−5(x−1)=2x+−1(2x)+(−1)(−3)

x−5(x−1)=2x+−2x+3

x+(−5)(x)+(−5)(−1)=2x+−2x+3(Distribute)

x+−5x+5=2x+−2x+3

(x+−5x)+(5)=(2x+−2x)+(3)(Combine Like Terms)

−4x+5=3

−4x+5=3

Step 2: Subtract 5 from both sides.

−4x+5−5=3−5

−4x=−2

Step 3: Divide both sides by -4.

−4x /−4 = −2 /−4

x = 1/2

To make a square for x²+bx=c, add( \frac{1}{2} b)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
