sergiy2304 [10]

Answer:

Required equation $\frac{1}{6.2}=\frac{15}{x}$

The height of statue of liberty is 93 meters.

Step-by-step explanation:

Given : Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1 inch : 6.2 meters.

To find : Which equation can Howard use to determine x, the height in meters, of the Statue of Liberty?

Solution :

The model is 15 inches tall.

The scale of the model to the actual statue is 1 inch : 6.2 meters.

Let x be the height in meters of the Statue of Liberty.

According to question, required equation is

$\frac{1}{6.2}=\frac{15}{x}$

Cross multiply,

$x=15\times 6.2$

$x=93$

Therefore, the height of statue of liberty is 93 meters.

X+y=4 and 2x+3y=2 then find x and y

Sladkaya [172]

Answer:

x=10, y=-6

Step-by-step explanation:

1) express x from the first equation x+y=4 x=4-y

2) It is the system of equations, so both equations are simultaneous.

you can replace x to 4-y in the second one

2 *(4-y) +3y=2

8-2y+3y= 2

y=-6

x= 4-y=4-(-6)=10

The answer is x=10, y=-6
