Answer:
-31
Step-by-step explanation:
a - 8x will change to (-7) - 8(3) = -31
Answer:
-2 and 21/50
Step-by-step explanation:
PEMDAS says that paranthases go first, so we solve 2 and 1/5 minus 33/12. 2 and 1/5 simplifies to the improper fraction, 11/5. Then we find a common denominater between 11/5 and 33/12 to get 60. 11/5=132/60, and 33/12=165/60. (132/60)-(165/60)=-33/60. Then we multipl that by 4 and 2/5, which can simplify to the improper fraction, 22/5. (22/5)*(-33/60) is -726/300, and simplifies to -2 and 21/50. Hope this helps!

Sure! I'll look you up!
Step-by-step explanation:
Chris and Jim must replace a <em>total</em> quantity of 17 tyres.
<h3>What is the minimum number of tyres to be replaced?</h3>
In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:
(25/20) · x - x ≥ 3
(5/20) · x ≥ 3
x ≥ 12
Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.
