Step-by-step explanation:
When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).
=> Last digit = 0 or 5.
Since 0 is not an option here, the answer must be 5. (C)
(leave the 15 alone for the duration of the sum)
= 5*675 - 5*3*210 - 210 ------------------------------ time's out bracket
=5*675 -210(5*3 +1) ---------------------------- took out common "-210" out of last
two terms'
= 5*675 -210(15+1)
= 5*675 -210(16)
=5*675 -210*16
Answer:
-1 x 2 = -2
Step-by-step explanation:
f(-1)=-1 x 2+1 = -1
-1 x 2 = -2
-2 + 1 = -1
g(-1) = 3 x -1 +5 = 2
3 x -1 + -3
-3 + 5 = 2

Answer:
8.4 (42/5)
well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.
