7+3=10
60/10=6
6x7=42
6x3=18
there is 18 trucks in the parking lot
Answer:
B. 7(6x – 1) and 42x – 7 is equivalent
Step-by-step explanation:
A. –3(3x + 5) and –9x + 5
=–3(3x + 5)=-9x-15 not equivalent
B. 7(6x – 1) and 42x – 7
7(6x – 1)=42x-7 equivalent
C. –6(4x – 3) and –6x
=–6(4x – 3)=-24+18 not equivalent
D. 5(2x + 3y) and 25xy
=5(2x + 3y)=10x+15y not equivalent.
Factors of 26 are 1, 2, 13, 26 all you have to do is figure out which numbers can go until a number and in this case the number is 26.
Total rental cost = $390 = 2($30/day) + ($0.25/mile)x (x=number of miles)
330
Then 390 = 60 + 0.25x => 330 = 0.25 x => x = ------------
0.25
x comes out to 1320 miles.
