The second one, 2.75 is to left of 3 on the numberline and it is less than 3
Answer: x=y+5
Step-by-step explanation:
Add 5 to both sides:
y+5=x-5+5
y+5=x
Answer:
a=9 , b=14
Step-by-step explanation:
Just do the operation (x+7)(x+2)
x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14
Answer:
1836 bacteria
Step-by-step explanation:
Now the data is a progression; 38,000, 33,820, 30,100 .........
We can find out what type of progression it is, in this case, we can see that it is a geometric progression because;
r= 33,820/38,000 = 30,100/33,820 = 0.89
So, for a geometric progression;
Un = ar^n-1
Where;
a = 38,000
r = 0.89
n = 27 days
Un = ???
Un = 38,000 * (0.89)^27 - 1
Un = 1836 bacteria
