Answer:
9 minutes
Step-by-step explanation:
First, you will want to add up all the time spent per problem.
3(9.5)+2(8.25)=45
Then, divide 9 from 45. 45÷5=9.
Therefore, she would have spent 9 minutes per problem.
Answer:
x = 8.5
Step-by-step explanation:
4x-5=9+20 (evaluate right side)
4x - 5 = 29 (add 5 to both sides)
4x = 29 + 5
4x = 34 (divide both sides by 4)
x = 34/4
x = 8.5
Answer:
See attachment.
Step-by-step explanation:
The given inequality is -2 < x - 3 < 5.
We add 3 to each part of -2 +3< x - 3+3 < 5+3
We now simplify to get: 1 < x < 8.
To represent this on the number line, we have to draw open circles at 1 and 8 and connect them as shown in the attachment.
