Answer:
b= -5
Step-by-step explanation:
-10(10+b)=5(3b+5)
Distribute
-100 -10b = 15b +25
Add 10b to each side
-100-10b+10b = 15b+10b +25
-100 = 25b+25
Subtract 25 from each side
-100-25 = 25b+25-25
-125 = 25b
Divide by 25
-125/25 =25b/25
-5 =b

Answer:
6 work out sessions
Step-by-step explanation:
From the above question, we know that:
Jasmine has a goal to workout a total of at least 6 hours this week.
Her workout sessions are always 3/4 an hour long.
Hence: Her total workout sessions
3/4 hour = 1 workout session
6 hours = x
Cross Multiply
3/4 × x = 6 × 1
x = 6/3/4
x = 6 ÷ 3/4
x = 6 × 4/3
x = 8 work out sessions
We are told that:
She already worked out for 1 1/2 hours.
Hence: if :
3/4 hour = 1 workout session
1 1/2 hours = x
Cross Multiply
3/4 × x = 1 1/2
x = 1 1/2 ÷ 3/4
x = 3/2 ÷ 3/4
x = 3/2 × 4/3
x = 2 work out sessions
Therefore:
the minimum number of workout sessions she would need to complete in order to achieve her weekly goal is calculated as:
8 work out sessions - 2 work out sessions
= 6 work out sessions
Converting this to workout sessions
