Answer:
-0.258620689
Step-by-step explanation:
Answer:
it has one solution
Step-by-step explanation:
1.y=x-3
2. 3y-3x sub x-3 in place of y therefore
it can also be written as 3x-3x-9=9
if you add 9 to both sides 3x-3x-9+9=-9+9
0+0=0
This is equivalent to:
(2.2533/2.59)(10^8/10^4)
(0.87)(10^4) which is:
0.87X10^4 which is equal to:
0.87X10000 which is equal to:
8.7X1000 and since 1000=10^3 we can say:
8.7X10^3
Answer:
Step-by-step explanation:
Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.
Given ratio= elementary schools: middle schools:: 28:16
The ratio can be written as 
Now to write into simplest form, we need to divide both numerator and denominator by 4.
∴ elementary schools: middle schools= 
Hence, we get simplest ratio of elementary schools to middle schools=
Answer:
160 children
Step-by-step explanation:
We can get this solution by working backwards in the equation.
First, we can treat the total number of strudents who play tennis as 't'. Giving us the equation: 8 = .25(t) . Solving this we get that there are 32 tennis players.
Next, we have to derive the total number of children in the sports club. Setting up 'x' as the total number of children, I get the equation 32 = .2(x) . Which leads us to the solution of 160 children in the sports club.
