9x-84=4x-18
5x=66
x=13.2
your number is 13.2
Given that the image was dilated by scale factor 3 then:
a] Length of the dilated side will be:
length/width=(original length/width)*(scale factor)
length=3*10=30 in
Width=3*6=18 in
thus the dimensions of the new image will be:
30 in by 18 in
b. The diagram below represent s the rectangle. 1 cm represent 10 inches
Answer:
Answers A and B
Step-by-step explanation:
To divide fractions, you keep, change, flip. Keep the first fraction the same, 4/11. Change the division sign into a multiplication sign. Finally, find the reciprocal or "flip" the last fraction into 15/9. This makes the equation 4/11 x 15/9. Multiply across the top to get 60, and the bottom to get 99. This makes 60/99. Therefore, answer A is correct. Find some more equivelent fractions by multiplying or dividing the top and bottom by the same amount. In this proccess, you can find that answer B is also correct.
Assuming both Mario and Todd just walked today.
Mario is every 8 days
Todd is every 14 days.
The days that will coincide is the Least Common Multiple (LCM) of 8 and 14
2 / 8 14
2 / 4 7
2 / 2 7
7 / 1 7
/ 1 1
The LCM = 2 * 2* 2* 7 = 56
The will both walk together in the next 56 days.
