Answer:
3a. yes
3b. y= 75x
3c. 600 mi
3d. 10 inches
Step-by-step explanation:
3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.
3b: y would equal the amount of inches multiplied by 75, so y=75x
3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles
3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches
Answer:
x = 6
Step-by-step explanation:
3 - 2x + 6 = 2x - 9 - 6
- 2x - 2x = - 9 - 6 - 3 - 6
- 4x = - 24
- x = - 24/4
- x = - 6
x = 6
Answer:
x=0
Step-by-step explanation:
2(3x-1)=6x-2
6x-2=6x-2
then plus two on both sides
6x=6x
x=0
Answer:
The two figures are similar and hey are not solid.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leah claims that these figures are not similar. When she compared the heights, she wrote 2/7. Then she compared the bases and 21/6. Why is Leah having trouble? Explain completely</em>
(Please have a look at the attached photo)
My answer:
In the first ratio, she compared the small figure's height to the large figure's height that is: 2/7
In the second ratio, she compared the large figure's base to the small figure's base that is: 21/6
=> She is wrong in this step, the ratio must be 6/21
Hence she needs to compare bases and heights thorugh division because the ratio between heights and the ratio between bases must be equal
The scales are equal
=> Therefore, those rectangles are congruent.
Looks like an angle bisector to me
