Does 2x-7=1/3(6x-12) + (-3) have one solution, infinitely many solutions, or no solutions? Please show how you got the answer and explain ty!!

Answer:

Step-by-step explanation:

lets take 2[tex]\frac{2}{5}[/tex] - 1[tex]\frac{3}{10}[/tex]

you have to convert 2 into [tex]\frac{10}{5}[/tex] so it would be [tex]\frac{12}{5}[/tex]

you also have to convert 1 into [tex]\frac{10}{10}[/tex] so it would be [tex]\frac{13}{10}[/tex]

since the denominators and different were ganna have to make them the same by mutiplying

you can easily do 5x2 to get 10

since you multiplied by 2 on the bottom do it on the top and you will get [tex]\frac{24}{10}[/tex]

now subtract them [tex]\frac{24}{10}[/tex]-[tex]\frac{13}{10}[/tex]=[tex]\frac{11}{10}[/tex]

24-13=11 but you need to simplify it and make it [tex]1\frac{1}{10}[/tex]

Answer:

Step-by-step explanation:

There are only two even numbers greater than 4, 6 and 8 specifically and there are a total of 8 numbers on the spinner so

P(E>4)=2/8=1/4

The answer is option C.

because, there are 8 parts in the spinning wheel. which mean the bottom part is gonna be 8. its not 7 because, the closer number is 1. so that means the answer is option D. but if you simply it you'll get 1/4.

sorry if wrong.

Answer:

Answer:

C. and E.

Step-by-step explanation:

Those options are the only ones that have 7th grade STUDENTS in them. In other words, the other options have other grades and teachers which are not what is necessary for this problem.

Have a good day and good luck!

Answer:

7

Step-by-step explanation:

x * x = 7x

7 x 7 = 7 x 7

49 = 49

so if x is 7, the equation is true...

Answer:

i would think false- sorry if it's not correct :/

Step-by-step explanation:

We should divide x^2-2 from the equation.

I will spare you from the boring steps of equation dividing.

Now getting 5x+4

Just do this like you are doing long division but instead using variables, be careful there is no x term in the second expression so you have to give it an empty space :)

Answer:

11m^2

Step-by-step explanation:

So first it would probably help to split it into different shapes. then you find the area of those shapes and add them.  

36 + 45 + 30 = 111 m^2

0.116+7.810=7.926

7+1=8

0.116 -------> 0

+ 7.81 --------> 8

7.926 -------> 8

Answer:

6 + 29t - 16t^2 = 18

16t^2 - 29t + 12 = 0

t = (29 +- √(29^2 - 4*12*16))/32

t = (29 +- √73)/32

t  = 0.639249882958827, 1.1732501170411

Step-by-step explanation:

The values of t for which the ball's height is 10 feet are approximately 0.71 seconds or 0.35 seconds

The given equation for the height of the ball is a quadratic equation, which is solved using the quadratic formula to find the values of t.

The quadrature formula for ax² + bx + c = 0 is:

[tex]x = \frac{-b \pm \sqrt{(b^2- 4ac)}}{2a}[/tex]

Given that,

The initial height of the ball: 6 feet

The initial upward velocity of the ball: 17 ft/s

The equation for the ball's height after t seconds: h = 6 + 17t - 16t²

The goal is to find the values of t for which the ball's height is 10 feet.

To find the values of t when the ball's height is 10 feet,

Set the equation h = 10 and solve for t.

Plugging in the given equation h = 6 + 17t - 16t²

And substituting h with 10, we get:

10 = 6 + 17t - 16t²

Rearrange the equation to solve for t.

16t² - 17t + 4 = 0

To find the values of t, we can use the quadratic formula:

In this case,

a = 16,

b = -17, and

c = 4.

Plugging these values into the quadratic formula, we get:

[tex]t = \frac{17 \pm \sqrt{((-17)^2- 4 \times 16 \times 4)}}{2 \times 16}[/tex]

Simplifying this equation, we have:

[tex]t = \frac{(17 \pm \sqrt{(289 - 256)}}{32}[/tex]

[tex]t = \frac{(17 \pm \sqrt{33})}{32}[/tex]

t ≈ 0.710 or 0.351

Hence,

Rounding to the nearest hundredth, we get two possible values for t:

t ≈ 0.71 seconds or 0.35 seconds
