Answer:
Let the distance from home to the park be x
Going to the park
Distance=vt
x=14t¹ ——(1)
Going back home
x=10t² ——(2)
Total time=t¹+t²
2.5=t¹+t²
Solving equ. 1 and 2 simultaneously
10x=140t¹
14x=140t²
Adding
4x=140(t¹+t²)
24x=140(2.5)
x=14.58 miles
Total distance= 2x
= 29.16miles

Step-by-step explanation:
These problems where you are not told what basic shape you are working with and have to assume some properties, just should not be asked. You are to assume that this is a parallelepiped.
The answer that you want is B
The length of the rectangle is 8 in given along the bottom. The top is also 8 in. The width of that rectangle is 4. The rectangle is the top of the drawing.
Answer: {y,x} = {4,2} ) ) ) )4
Step-by-step explanation: y
[2] y = -2x + 8
// Plug this in for variable y in equation [1]
[1] (-2x+8) - x = 2
[1] - 3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
y = -2x+8
x = 2
// Use the x value to solve for y
y = -2(2)+8 = 4
Solution :
{y,x} = {4,2}
Answer:
oh oh....I know...it's 4....I'm I right
To isolate the variable means to have it by itself on one side of the equation, where the variable equals an expression.
To isolate , we will need to remove the variables and other terms "connected" to the variable:
By dividing terms "connected" to our variable, we have isolated it one side of the equation.
