6,378.1 - 2,981.1

= 6,000 + 300 + 70 + 8 + 1/10 - 2,000 - 900 - 80 - 1 - 1/10

= (6,000 - 2,000) + (300 - 900) + (70 - 80) + (8-1) + (1/10-1/10)

= 4,000 - 600 - 10 + 7 + 0

= 3,400 - 3 

= 3,397

I’m the triangle shown below what is the approximate value of x
Dafna1 [17]

Answer:

The answer is choice B: 22.52 units.

Step-by-step explanation:

We use the Pythagoras's theorem which says for a right triangle with sides x,y and hypotenuse z:

x^2+y^2=z^2.

In our case

z=26

y=13

So we solve for x:

x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2}  =\boxed{22.52\: units.}

Which is choice B.

Find y when x = 12, if y = 2 when x = 5
AleksAgata [21]
Y = kx
k = y/x
k = 2/12
k = 1/6

so when x = 12
y = kx
y = 1/6(5)
y = 5/6

answer
when x = 5  y = 5/6

How do I solve the inequality for this: 10 < 9 + x
Firlakuza [10]
Subtract 9 from each side of the equation. so you would get 1<x. meaning that any number larger then 1 would correctly solve the equation.

Please help guys need help
dmitriy555 [2]

Answer:

A) slope = 20.

B)  The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Step-by-step explanation:

Recall that slope is y2 - y1 / x2 - x1.

Excellent. We are provided with two points: (1, 60) and (3, 100). Let’s enter this into our formula.

Slope = (100 - 60) / (3 - 1) = 40 / 2 = 20.

Now, to determine what the slope means, we can look at the axis titles on the graph. The x axis title is hours, or time in hours. The y axis title is price of the service call in dollars. Therefore, the slope is price (in dollars) per time (in hours).

This can be restated as: The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Hope this helps!
