Answer: Choice B (If you need to do questions like this in the future i recommend using the desmos graphing calculator online, inputting the equations and comparing them)
Answer:
The first step to simplify any expression is by removing the brackets if there is anyone and in the other hand by removing the parenthesis like in this case
Step-by-step explanation:
First one must apply the distributive property multiplying the variable -x by all the subjects in the parenthesis like 2 and -3x in this case to get -2x and 6x^2, remember to apply the property of signs multiplication in all the cases.
6. 2 h 14 min= 134 min
134min/26.2 mi = 5.114 min/mi
7. 9834.9-8546.3=1348.6 mi
1348.6 mi/65.4 gal=20.6 mi/gal
8. 5 miles = .4x
x=5/.4
x=12.5 laps
9. 8 x 3600=28800 sec
28800/8001=3.6 sec/kiss
Answer:
3
Step-by-step explanation:
maria's number is x.
6x+7=25
-7 -7
6x=18
/6 /6
x=3
21 and 2/3 all divided by 1 and 2/3 = answer
answer = 13
