Answer:
For the first image, the answer should be C) 11 ft.
For the second image, the answer should be C) 6 mi.
For the third image, the answer should be C) 6.9 m^2
Step-by-step explanation:
First image explaination: To get the area of a rectangle you would multiply length times width. 7 times 11 is the area given: 77- so the answer should be 11 ft.
Second image explaination: Divide 11.4 by 1.9.
Third image explaination: Divide 41.4 by 6.
All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
