Answer: D. None of the above
midpoint formula : (x2-x1) , (y2-y1)
(8-11)/2 , (7-9)/2
-1.5 , -1
Answer:
The solution to the equation is:
- <u>x = 2.5</u> or <u>x = 5/2</u>
Step-by-step explanation:
To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:
And we solve:
- 4x + 28 = 38 (we multiply 4 by x and 7)
- 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
- x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
- <u>x = 2.5</u> (we divide)
As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>
Answer:189
Step-by-step explanation:
Alright, so all we have to do here is solve the equation!
5 5/8 + m = 9
m = 9 - 5 5/8
Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).
m = 8 8/8 - 5 5/8
Then we can subtract fairly easily!
m = (8 - 5) + (8/8 - 5/8)
m = 3 3/8 miles
Hope this helps!! :)
Answer:
24 blue cars
Step-by-step explanation:
In this problem, one is given the ratio of red to blue cars in the parking lot. One is given the actual number of red cars, and one is asked to find the number of blue cars. One can set up a proportion; ratio to actual, then solve to find the number of actual blue cars using the method of cross-products. One can set up the proportion using the ratios, but it is easier to express the proportion as the equality of two fractions. Thus, the following equation can be formed, let the parameter (x) represent the actual amount of blue cars;
Cross products,
Inverse operations,
