Answer:
x(x-5)=176
Step-by-step explanation:
If x is meant to be the greater integer, then it only makes sense to subtract five from it in order to find the value of the second integer, then multiplying them together
Equation of the table is given by
y - 210 = (280 - 210)/(4 - 3) (x - 3)
y - 210 = 70(x - 3)
y - 210 = 70x - 210
y = 70x
When x = 11, y = 70(11) = 770
Equation of the graph is given by
y = 110/2 x = 55x
When x = 11, y = 55(11) = 605
Therefore the value of y in the table is grater than the value of y in the graph by 770 - 605 = 165
Answer:
Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
Answer:
736x-89
Step-by-step explanation:
i think all you can do here is add the numbers that have an X in them so adding 689x+47x=736x and you leave the 89 so it becomes 736x-89
