Lisa has a certain amount of money. She spent $39 and has 3/4 of the original amount left. How much money did she have originall
antiseptic1488 [7]
We know that she spent $39, and has 3/4 of the original amount left. Our goal is to find the original amount. We can use the equation. x - 39 = 3/4x. Once we subtract x on the left hand side, we get -39 = -1/4x. Once we multiply -39 by -4, we get 146. She originally had $156.

Given f(x) = -3x + 5, find the value for f (7).
Lorico [155]

Answer:

-16.

Step-by-step explanation:

Given that f(x) = -3 times x + 5.

We need to find the value of f(7).

Hence we need to put x = 7 in the given function.

Hence f(7) = -3 times 7 + 5 = -16.

Inside a square with side length 10, two congruent equilateral triangles are drawn such that they share one side and each has on
Sphinxa [80]

Answer:

5 length

Step-by-step explanation:

The diagram attached shows two equilateral triangles ABC & CDE. Since both squares share  one side of the square  BDFH of length 10, then their lengths will be 5 each. To obtain the largest square inscribed inside the original square BDFH, it makes sense to draw two other equilateral triangles AGH & EFG at the upper part of BDFH with length equal to 5.

So, the largest square that can be inscribe in the space outside the two equilateral triangles ABC & CDE and within BDFH is the square ACEG.
