–4 times a number plus 16 is –116. Find the number. Answer:
Mathematics
1 answer:
SpyIntel [72]3 years ago
4 0
Equation
-4x + 16 = -116

solve for x
-4x + 16 = -116

subtract 16 to both sides
-4x + 16 - 16 = -116 - 16

simplify
-4x = -132

divide -4 to both sides
-4x/-4 = -132/-4

simplify
x = 33

answer: the number is 33

What is 8,792 as a fraction?
Wittaler [7]

We have a number 8.792.

To write it as a fraction first count the number of decimals and call it n (which, in our case, has a value of 3). Multiply the number with 10^n to get 8792. Then divide this number by 10^n to get \frac{8792}{10^n} from here you can either simplify (if the assignment says so, then the simplified fraction is \frac{1099}{125}) or not.

Hope this helps.

Un edificio proyecta una sombra de 7.5m.mientras que un arbol que mide 1.6 m de altura proyecta una sombra 1.85 M¿Cual es la alt
sattari [20]

Answer: The height of the building is 6.49 meters.

Step-by-step explanation:

This can be translated to:

"A building projects a 7.5 m shadow, while a tree with a height of 1.6 m projects a shadow of 1.85 m.

Which is the height of the building?"

We can conclude that the ratio between the projected shadow is and the actual height is constant for both objects, this means that if H is the height of the building, we need to have:

(height of the building)/(shadow of the building) = (height of the tree)/(shadow of the tree)

H/7.5m = 1.6m/1.85m

H = (1.6m/1.85m)*7.5m = 6.49m

The height of the building is 6.49 meters.
