Answer:
7.69% increase
Step-by-step explanation:
Let our initial number be 100
11% decrease will be;
100- 0.11(100) = 100-11 = 89
A 21% increase will be;
89 + 21% of 89
89 + 0.21(89)
= 107.69
difference from the starting is 107.69 - 100 = 7.69
The percentage is 7.69% increase
I agree because he calculated it the right way and that is the same answer I got.
Hope I helped :)
Answer:
t = 2
Step-by-step explanation:
5(6t-3)=5t+35
Step 1 distribute the 5 by multiplying 5 to what is inside of the parenthesis
5(6t) - 5(3) = 5t + 35
Outcome: 30t - 15 = 5t + 35
Step 2 add 15 to both sides
30t - 15 + 15 = 5t + 35 + 15
Outcome: 30t = 5t + 50
Step 3 subtract 5t from both sides
30t - 5t = 5t - 5t + 50
Outcome: 25t = 50
Step 4 divide both sides by 25
25t/25 = 50 we're left with t = 2
2.62 is the answer but there’s actually way more numbers than that
