What is the variable "x" in the equation, 7/2=x/2, and why?

1 answer:

7 0

X is equal to 7. Since you are trying to make them equal to each other, the denominator is already the same, so you just need to make the numerator the same too.

The graph shows the increase of the temperature over time in an oven what is the change in the y value and x value on the graph

Hatshy [7]

Let

x-------> the time in minutes

y-------> the temperature in Fahrenheit degrees

$A(2,150)\\B(3,190)$

we know that

the change in the y-values between two points is equal to

$(y2-y1)$

Substitute the y-values of the point A and B in the formula

$y2=190\\y1=150$

$(190-150)=40$

the change in the x-values between two points is equal to

$(x2-x1)$

Substitute the x-values of the point A and B in the formula

$x2=3\\x1=2$

$(3-2)=1$

therefore

the answer is

The change in the y-value is $40$ and the change in the x-value is $1$

Answer:

$\frac{-117}{10}$

Step-by-step explanation:

1) Change the mixed fractions into improper fractions:

$-3\frac{1}{5} + (-8\frac{1}{2} )\\= \frac{-16}{5} - \frac{17}{2}$

2) Multiply the first fraction by 2/2 and the second fraction by 5/5 in order to create common factors on the denominator (You can do this because you are essentially multiplying by one, for example 2/2 = 1):

$\frac{-16}{5} *\frac{2}{2} - \frac{-17}{2} * \frac{5}{5} \\ =\frac{-32}{10} - \frac{85}{10}$

3) Simplify the numerator(top part) while keeping the denominator(bottom part) the same:

$\frac{-32}{10} -\frac{85}{10} \\\\=\frac{-32 - 85}{10}\\ \\= \frac{-117}{10}$

Sylvia took three times in a video game she scored -120 points during her first turn 320 points in her second time and -80 point

sp2606 [1]

Her average score for the 3 turns is 40 because you have to add all of the scores so -80 and -120 is -200 so add that to 320 and you get 120 divide that by 3 because she took 3 turns and you get 40
