what is:  x + 3 -    2x -1  = 4

                 5            3

               

Answers

Answer 1
Answer: (x + 3)/5 - (2x - 1)/3 = 4 / * 15

3(x + 3) - 5(2x - 1) = 15 * 4

3x + 9 - 10x + 5 = 60

7x = 60 - 9 - 5

7x = 46 / : 7

x = 6 4/7

Answer 2
Answer:

Answer:

X= -46/7

Step-by-step explanation:

step1:  left part times 15 is   3(X+3)-5(2X-1)

step2: right part times 15 is 60

step3:   3(X+3)-5(2X-1)=60

step4:   3X+9-10X+5=60

step5:   -7X+14=60

step6:   -7X=46

step7:      X= -46/7

What is the perimeter of a triangle having side lengths of 8 cm, 10 cm and 6 cm?

Answers

perimeter is all of the sides added up. 
Soooo
8 + 10 + 6 = 24 
So the perimeter of this triangle is 24cm 

love, the Pineapple. 
We just need to add up all of the side lengths, 

8 + 10 + 6 = 24 cm 

Choose the equation of the vertical line passing through the point (−4, 2).y = −4

x = −4

y = 2

x = 2

Answers

Answer:

Equation would be  x = - 4 .

Step-by-step explanation:

Given :  vertical line passing through the point (−4, 2).

To find : Choose the equation of the vertical line .

Solution : We have given that  point (−4, 2).

We know that vertical line always passes through the x axis .

Here, line passes through at x = -4  which has no slope .

Therefore , equation would be  x = - 4 .
Vertical line has no slope. so only look at the x value. x=-4.

The total of a triangle must be 180 degrees, so since c = z, then z is 35 degrees, add that to the 65 degrees of angle x to get 100, so the angle must be an 80 degrees, so angle y is 80 degrees

Sam is observing the velocity of a car at different times. After three hours, the velocity of the car is 51 km/h. After five hours, the velocity of the car is 59 km/h. Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5 points) Part B: How can you graph the equation obtained in Part A for the first six hours?

Answers

Assuming that the car is travelling at constant acceleration, follows the equation: v = (v_in) + at where v = velocity v_in = initial velocity, (at t = 0) a = acceleration t = time Given the conditions, v = 51 at t = 3, and v = 59 at t = 5 Eqn 1: 51 = (v_in) + a(3) Eqn 2: 59 = (v_in) + a(5) Solving for v_in and a (using a calculator) v_in = 39 a = 4 therefore the equation for the motion of the car is: v = 39 + 4t This equation can be plotted using excel or wolframalpha.
