Answer:

x=5

Step-by-step explanation:

x+2=2x-3

-x on both sides=

2= x-3

then -2 on both sides

0= x-5

this means that x must be 5 so that positive 5- negative 5 equals 0 :)

Answer:

5

Step-by-step explanation:

since the sides are the same size, then the equation should be combined into x+2=2x-3

then subtract an x from both sides: 2=x-3

then add 3 to both sides: 5=x

and you have your answer

hope this works

The function f(t) =16t 2 + 248 models the height f(t) in feet of a stone t seconds after it is dropped from the edge of a vertic
Hatshy [7]

Answer:

The time it takes for the stone to reach the ground is 3.94 s. This answer is correct.

Step-by-step explanation:

I believe there's a mistake in the equation shown, the acceleration (number that multiplies t²) should be negative, since the stone is falling, therefore I'll answer assuming it's -16 instead of 16, otherwise there would be no real solution to the equation.

In order to calculate how long it'll take for the stone to hit the ground we must make f(t) = 0 and find the time "t" that makes the equation valid, so we have:

f(t) = -16t² + 248 = 0

-16t² = -248

t² = -248/(-16) = 15.5

t = sqrt(15.5) = 3.94

Usimov [2.4K]

Point of intersection is the solution of the system of equations.

Both of them intersect at point (-3,5)

So, (-3,5) is the solution of the system of equations.

The length of a rectangle is 5 cm less than 3 times its width. If the perimeter is 70 cm, find the dimensions.
zvonat [6]

Answer:

l = 25

w = 10

Step-by-step explanation:

w = width

3w-5 = length

w+w+3w-5+3w-5 = 70

8w - 10 = 70

8w = 80

w = 10

l = 3(10)-5, or 25
