Answer:
7
Step-by-step explanation:
Subtract cost of stationary from total in account
98 - 10.85 = 87.15
Subtract cost of skateboard from new total
87.15 - 64 = 23.15
Set up an algebraic expression
23.15 = 1.65x
Divide each side by 1.65 to isolate x
x = 14.0303 or 14
Answer:GCF of 45 and 63 is 9.
Step-by-step explanation:
factors of 45 are 1,3,5,9,15,45
factors of 63 are 1,3,7,9,21,63
so the greatest common factor or GCF of 45 and 63 is 9
Hello from MrBillDoesMath!
Answer:
The equation is x + ( x+ 2) + (x+4 ) = 72
(while not asked, x = 22 is the solution)
Discussion:
We are given that
x + ( x+ 2) + (x+4 ) = 72 => (combine like terms)
3x + 6 = 72 => (subtract 6 from each side)
3x = 72 -6 = 66 =>
x = 66/3 = 22
Thank you,
