Answer: x ≥ -4 (in words: x is greater than or equal to -4)
Step-by-step explanation:
The number line shows all values greater than -4 being shaded in, meaning that x can be any of them. In addition, the point at -4 itself is shaded in, showing that it is also a possible value for x.
The Middle school won 17 games so the senior school won 51 games
Let x be quarters, and y be nickels.
0.25x + 0.05y = 11.50
x + y = 66
x= 66 - y
0.25(66-y)+0.05y=11.50
16.5 -0.25y+0.05y = 11.50
16.5-0.2y=11.50
-0.2y=11.50-16.5
-0.2y=-5
-0.2y/-0.22=-5/-0.2
y=25
x+y=66
x+(25)=66
x=66-25
x=41
So there are 41 quarters, and 25 nickels.
This is a really easy problem.
All you have to do is do 12 divided by 75%.
If you don't have a calculator, turn 75% into 3/4
3/4 times 12 which is
16
I hope i helped!:)
Answer:
d So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered
Step-by-step explanation:
When we have an equation of the form
y = ab^x
a is the initial value at time x=0
b is the growth (or decay ) factor
and x is the time
So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered
