You should be able to answer this by glancing at it. But if you can't,
then you have to set up an equation.
Call the unknown number ' Z '.
You said that 0.4 = 10 Z
Divide each side of the equation by 10 : Z = 0.4 / 10 = <em>0.04</em>
Answer:
The slope is -3/4 or -0.75
Step-by-step explanation:
You can solve this using the slope of a line formula:
m = slope
= coordinates of first point in the line
= coordinates of second point in the line
Now all you have to do is plug your numbers in and solve!
Answer:
Quadrilateral ABCD does not map onto itself using a reflection because it has 0 lines of symmetry.
Step-by-step explanation:
Remember that a trapezoid has no lines of symmetry.
<span>Let x be the speed of the first car, then (x + 10) is the speed of the second car.
We can write the equation by the condition of the problem:
</span>
mph s<span>peed of the first car
</span>
Then 30+10=40 mph speed of the second car
Answer: 30mph and 40 mph.

The errors are that she is just multiplying incorrectly.
10* 1.75 = 17.5
100* 1.75= 175
1000* 1.75 = 1750
When you are multiplying by tens (hundreds and thousands are also considered tens since they are just 10*10 and 10*10*10), you should just be moving the decimal place forward one place.
This goes back to very basic math when you are learning place values.
