Model of Statue of Liberty is 30.6 feet tall.
<u>Step-by-step explanation:</u>
Given the Statue of Liberty is 306 feet tall. If the model is 1/10 the actual size of the Statue of Liberty.
Actual size of the statue = 306
Model is 
of the actual size of the Statue of Liberty
Height of model = of the actual size
= * 306
= 30.6 feet
Model of Statue of Liberty is 30.6 feet tall.
Answer:
x = -2
x = -9
Step-by-step explanation:
The linear system is:
8x - 4y = 20 ⇒ (1)
5x - 8y = 62 ⇒ (2)
To solve the system multiply equation (1) by -2 to make the coefficients of y equal in values and different in signs, then add the resulting equation with equation (2)
∵ -2(8x) + -2(-4y) = -2(20)
∴ -16x + 8y = -40 ⇒ (3)
- Add equation (2) and (3)
∴ -11x = 22
- Divide both sides by -11
∴ x = -2
Substitute the value of x in equation (1) or (2)
∵ 8(-2) - 4y = 20
∴ -16 - 4y = 20
- Add 16 to both sides
∴ - 4y = 36
- Divide both sides by -4
∴ y = -9
27x + 9
------------
3
Break down the fraction. 3 is the common denominator, so it is the denominator of both numerators.
27x/3 + 9/3 = 0
9x + 3 = 0
9x = -3
x = -3/9 simplified to x = -1/3
Or simply multiply the fraction with 3/1 to remove the denominator, which is 3.
27x + 9 3 27x + 9
----------- x ------- = ----------------- or 27x + 9 = 0 ; look for x.
3 1 1
To check: Substitute x by its value:
(27x + 9) / 3 = 0 ⇒ ((27 * -1/3) + 9) / 3 = 0
⇒ (-9 + 9)/3 = 0 ⇒ 0/3 = 0 ⇒ 0 = 0
