4+8+(5X7)+5(7-9)=6+B
USE PEMDAS
5X7=35
4+8+35+5(7-9)=6+B
(7-9)=-2
4+8+35+5(-2)=6+B
5X-2=-10
4+8+35+-10=6+B
4+8+35+-10=37
minus both sides by 6
37-6=31
6+B-6=B
31=B or B=31
I think it takes her brother 30 minutes to complete his homework.
Because 3/5 of an hour is 36/60
5/6 = 30/36
Hope this helps! :)
Answer:
x-intercept= (5,0)
y-intercept= (0,-2)
Slope= 2/5
Step-by-step explanation:
its C the only one that makes a angle
Since it's 0.6 kg for 5 gallons, we'd want to find the unit rate aka the amount of kg's per gallon. To find that, we have to see how many times 5 goes into 0.6, which is 0.6/5=0.12 for 1 gallon. Multiply that by 7 to get 0.84 for 7 gallons!
