A pole that is 3.2 m tall casts a shadow that is 1.45 m long. At the same time, a nearby building casts a shadow that is 36.5 m

Usimov [2.4K]

To solve this, use proportions. The height of the pole corresponds to the height of the building; the shadows are corresponding: 3.1/x =1/45.5
3.1 times 45.5=1x
141.05=x
The building is 141 meters tall

(1 + 7x) - 6 * (-7 - x) = 36<br> step pls

AlladinOne [14]

Answer:

-7/13

Step-by-step explanation:

(1 + 7x) - 6 * (-7 - x) = 36 Distribute the 6 into (-7 - x)

1 + 7x + 42 + 6x = 36 Combine like terms (1 + 42) & (7x + 6x)

43 + 13x = 36 Subtract 43 from both sides

13x = -7 Divide by 13

x = -7/13

If (72)x = 1, what is the value of x? explain your answer

Eva8 [605]

(7^2)x = 1
x = 1/(7^2) = 7^(-2).

You obtain the value of x by dividing both sides by 7^2 and the inverse of 7^2 is 7^(-2).
