Question 9: 35 Question 10: 10
Step-by-step explanation:
Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).
Question 9:
Start with the brackets.
10 x 4 - (7 - 2)
= 10 x 4 - (5)
Then, multiply 10 and 4.
= 40 - 5
Solve the subtraction.
= 35
Question 10:
Start with the brackets.
1 - (2 - 3) + 8
= 1 - (-1) + 8
= 1 - - 1 + 8
(Two negatives = a positive)
= 1 + 1 + 8
Add the numbers.
= 10
Answer:
1 7/8 (1, 2)
Step-by-step explanation:
60/5=12 so dwayne reads 3/8 chapter per 12 minutes
12/3=4 so dwayne reads 1/8 chapter per 4 minutes
4x8=32 dwayne reads a chapter per 32 minutes.
2x32=64 and got 4 minute extra which is the time for dwayne to read 1/8 chapter
So Dwayne can read 1 7/8 chapter in 1 hour, if rounding off then 2 chapters, if only an entire chapter counts then 1
